Amaranthus viridis L.
A Cm: Crimea: Yalta vicinity, Nikita, Nikitsky Botanical Garden, Upper Park, 44°30′45.14″N, 34°13′52.61″E, 155 m, well-lit and heated flower bed under regular watering with planting of Iris cultivars, together with Amaranthus blitum L. and A. retroflexus L., 27 Aug 2018, Ryff (YALT). – Weed of American origin, which is now widespread in tropical and subtropical regions. It is also known in most countries of W and C Europe as an alien (Iamonico 2015+). In E Europe, A. viridis was not known until the end of the 20th century, although S. L. Mosyakin suggested the possibility of its detection there (Mosyakin 1995, 1996). Subsequently this species was indicated from Belarus (Parfenov 1999). It was also recorded in the N Caucasus and Transcaucasia (Zernov 2006; Menitsky 2012). This is the first report of A. viridis for the Crimean peninsula, where only one locality with a few specimens was found. Further monitoring is necessary to establish the status of this alien species in the region.
Campanulaceae (incl. Lobeliaceae)
Lobelia erinus L.
A Tn: Tunisia: Bizerte, Bizerte north, bordering the cor-niche, 37°19′51″N, 09°51′52″E, 5 m, coastal rock vegetation, few flowering individuals, 22 Jun 2018, El Mokni (herb. Univ. Monastir). – Lobelia erinus is native to southern Africa (cf. Thulin & al. 1986). It is a prostrate or scrambling herbaceous annual to perennial plant; stems ascendant, 10–20 cm tall, glabrous, caespitose with blue to violet, 5-lobed corolla (cf. Bojňanský & Fargašová 2007). Often planted as an ornamental in gardens, it has been reported as naturalized in some countries of Europe, viz. Portugal (Almeida & Freitas 2006) and the United Kingdom (cf. Bojňanský & Fargašová 2007) and as adventitious in France, Germany and the Canary Islands (Castroviejo & al. 2010). For N Africa, the species is listed as cultivated or sometimes subspontaneous only from Morocco (Dobignard & Chatelain 2011; APD 2018). It is here reported for the first time from Tunisia with the status of a casual alien.

Cerastium bulgaricum R. Uechtr.
+ Gr: Greece: Thraki, Nomos of Rodopi, Eparchia of Sapes, 4 km NW of village of Ourania near Bulgarian border, 41°18′N, 25°54′E, 1000 m, ridge in opening of Fagus forest, acid rocks, 9 May 2018, Strid & Hartvig 59300 (UPA, herb. Strid); ibid., Eparchia of Komotini, 14 km from Organi along road to Chloi, 41°17′N, 25°48′E, 600 m, rocky serpentine slopes with open Juniperus scrub, 10 May 2018, Strid & Hartvig 59362 (UPA). – The cited specimens are fruiting, with ripe seeds. Cerastium bulgaricum is a member of the C. gracile group, which has been treated very differently in recent Floras and is in need of modern, critical revision. Flora europaea (Whitehead 1993: 175) and Atlas florae europaeae (Jalas & Suominen 1983: 119) recognized only C. gracile Dufour, with a disjunct distribution in the Iberian Peninsula and NW Africa, and then again in SE Europe and Anatolia. This clearly represents excessive lumping, and it seems reasonable to follow the monographer Möschl (1943) in recognizing three species in SE Europe, viz. C. bulgaricum, C. ramosissimum Boiss. and C. schmalhausenii Pacz., whereas C. gracile s.str. is confined to the W Mediterranean area. Cerastium schmalhausenii is restricted to Crimea and adjacent areas, and C. bulgaricum occurs in Bulgaria and Banat, whereas C. ramosissimum is more widespread. In Flora hellenica (Strid 1997: 213–214), C. bulgaricum was reluctantly merged into C. ramosissimum. With more material now available, I believe the two species are rather distinct morphologically, geographically as well as ecologically. The main differences are as follows:
Cerastium ramosissimum: Whole plant often purplish, laxly branched, 10–20 cm tall, appearing slender; fruiting pedicels spreading or deflexed, longer than calyx; capsule c. 2.5 × as long as calyx; seeds 0.6–0.9 mm, medium brown to reddish brown, with subacute tubercles. Usually on serpentine (ophiolithic substrate).
Cerastium bulgaricum: Plant pale green, erect, 5–10 cm tall, sparingly branched above and sometimes from the base, appearing robust; fruiting pedicels suberect, shorter than calyx; capsule not more than 2 × as long as calyx; seeds 0.6–0.7 mm, pale to medium brown, with rounded tubercles. On various substrates.
The cited collections from NE Greece match the type of Cerastium bulgaricum (Sintenis 636, LD!) from Dobrudscha in NE Bulgaria as well as plants illustrated as C. bulgaricum by Möschl (1943: 167) and Velev (1966: 381). This taxon presumably occurs from NE Greece through Bulgaria to S and E Romania. All other Greek material in the C. gracile group is referable to C. ramosissimum. The latter is scattered in the C and SE mainland, Evvia and the East Aegean islands, whereas a record from Mt Tzena in NC Greece (Voliotis 1983: 163) is dubious. A somewhat similar species, C. dominici Favarger, occurs locally on serpentine substrate in SW Anatolia and the island of Rodos.
Spinacia tetrandra M. Bieb. – Fig. 1.
+ Rf(CS): Russia: Dagestan, Derbent district, 4 km W of Muzaim, valley of Kamyshchay river, 41°54′26″N, 48°14′03″E, c. 110 m, desert clayey slope, 13 Jun 2018, Fateryga (photo). – Spinacia tetrandra was described from the valley of the Kura river in Transcaucasia. Within the territory covered by the Euro+Med PlantBase, S. tetrandra was previously known from Armenia, Azerbaijan, Georgia, Jordan and Syria; the record from Turkey requires confirmation (Uotila 2011+). We hereby add Russia to the known distribution of this species. Since S. tetrandra was already known from Azerbaijan, its record in the bordering Republic of Dagestan of the Russian Federation is not surprising. Because the plants were recorded in a plant community of Suaeda microphylla Pall. (Chenopodiaceae) with low anthropogenic influence (Fig. 1A), the species seems to be native for Dagestan.

Hieracium sylvularum Jord. ex Boreau (≡ H. murorum subsp. sylvularum (Jord. ex Boreau) Zahn; = H. grandidens Dahlst.)
N No: Norway: Bergen City, Kalfaret, Kalvedalsveien, at Høyskolen Kristiania, 60.386514°N, 05.3489635°E, school yard, margins of managed lawns along pavement, also on steep street wall opposite to school, 17 Nov 2018, Sennikov & Feulner (H837885).
N Es, Rf(C, N, NW): Fennoscandia and Russia were misleadingly included in the native distribution of this species in Sell & West (1976) and Schljakov (1989), whereas the NE limit of its native distribution embraces C and S Lithuania, S Latvia and almost the whole of Belarus, excluding Scandinavia, Finland, Estonia and Russia (Sennikov 1999, 2002, 2003). Hylander (1943, 1948) demonstrated that this species was among the most common herbaceous plants introduced for ornamental purposes in historical parks of Denmark, Finland and Sweden, as part of the philosophical concept of the English garden style. This species is still the most abundant among nearly 100 alien species of Hieracium sect. Hieracium recognized in the latest revision in Sweden (Tyler 2004). Its local abundance even led Tyler & al. (2015) to include this species into the list of plants invasive in Sweden.
In Norway, this species was recorded (as Hieracium grandidens) for the first and only time in the park of the old manor “Kjørbo” in Bærum, Norway (Nordhagen 1954b). The species was found in association with Luzula luzuloides (Lam.) Dandy & Wilmott, typical of the historical ornamental introductions in old parks (Hylander 1943; Nordhagen 1954a). This locality was taken into account in Sell & West (1976) and included in the secondary distribution area of H. grandidens in the latest treatment of the Fennoscandian flora (Mossberg & Stenberg 2018).
In 2018, a small but apparently established population of this species was observed in secondary flower in Kalfaret, an eastern neighborhood of Bergen, the district east of the old city gates that had been traditionally populated with villas and residences of well-to-do citizens. Many of those houses with surrounding green territories, built mostly in the beginning of the 20th century, still survived and harbour the traces of historical park cultivation. This locality of Hieracium sylvularum is the second one in Norway, and more are expected to emerge when historical parks are closely inspected.
The status of Hieracium sylvularum in Norway should be changed to established alien, as well as its status in Estonia and Russia.

Symphyotrichum graminifolium (Spreng.) G. L. Nesom (≡ Aster squamatus var. graminifolius (Spreng.) Hieron. ≡ Conyza graminifolia Spreng. ≡ Conyzanthus graminifolius (Spreng.) Tamamsch.)
– Cm: In Crimea, this plant was identified as Conyzanthus graminifolius by S. K. Kozhevnikova in 1974 (Kozhevnikova & Makhaeva 1976; YALT). It has been included under this name in all subsequent floristic reports. Supposedly the species was brought to the Crimean peninsula from Yugoslavia with building materials during the construction of the hotel complex “Yalta-Intourist”. However, for the territory of the former Yugoslavia, as for other European and Mediterranean countries, only Symphyotrichum squamatum (Spreng.) G. L. Nesom is indicated, not S. graminifolium (Greuter 2006+). The morphological peculiarities of Kozhevnikova's specimens contradict the protologue of S. graminifolium, but correspond to the one of S. squamatum (Sprengel 1826). In particular, its stems are scabrous due to small, white glands and due to larger semitransparent vesicles that look like whitish or brownish scales on dry herbarium specimens. Such structures are also present in all other Crimean herbarium specimens and living plants that I have seen. The plant habit, size and shape of leaves vary greatly even in the same population depending on the habitat conditions and the growth phase of the individual, but it seems that the specimens of S. squamatum from Crimea are no different from plants growing in other regions. The error in the determination can be explained by the use of an imperfect diagnostic key in the Flora SSSR (Tamamschjan 1959). S. graminifolium does not qualify as a weed or alien species in any other country of the world, except the countries of the former USSR (Greuter 2006+; Randall 2017). Therefore, it is necessary to exclude S. graminifolium from the Crimean flora, since all known records are referable in fact to S. squa matum. See the following entry.
Symphyotrichum squamatum (Spreng.) G. L. Nesom (≡ Aster squamatus (Spreng.) Hieron. ≡ Conyza squamata Spreng. ≡ Conyzanthus squamatus (Spreng.) Tamamsch.) N Cm: Crimea: Yalta vicinity, Lower Massandra, near hotel complex “Yalta-Intourist”, 11 Nov 1974, Kozhevnikova (YALT); Yalta, Kotelnikova Str., 44°29′29″N, 34°08′56″E, 40 m, 7 Oct 2011, Ryff (YALT); ibid., 44°29′20.47″N, 34°09′44.85″E, 5 m, embankment, 18 Sep 2014, Svirin (YALT); ibid., Rudanskogo Str., in the square, 44°29′51″N, 34°10′21″E, 14 m, 15 Sep 2018, Ryff (YALT); Gurzuf vicinity, 17 Oct 2010, Ryff (YALT); Gurzuf, 44°31′55″N, 34°16′22″E, 5 m, recreation complex “Zhemchuzhina Kryma”, embankment, 16 Sep 2018, Ryff (YALT); Alushta, 44°40′40″N, 34°25′15″E, 5 m, embankment, 24 Oct 2014, Ryff (YALT); Sevastopol, upper Kamyshovaya bay, 44°34′40″N, 33°26′05″E, 0–2 m, shipyard, 29 Jul 2014, Svirin, Seregin & Yevseenkov (MW); ibid., Kamyshovaya bay, 44°34′33.68″N, 33°26′10.10″E, shipyard, 17 Sep 2014, Svirin (YALT) (all as Conyzanthus graminifolius). – Growing in and along streets, pavements, embankments, roadsides, industrial sites, asphalt and concrete areas, flowerbeds and watersides. Symphyotrichum squamatum sometimes grows together with Erigeron canadensis L. and E. sumatrensis Retz. This is the first record of this alien for E Europe. Over the past decades, S. squamatum has been notably spreading in SW Crimea. Actually it is registered in anthropogenic habitats only, but potentially it can become invasive along the Black Sea coast and in salt marshes of the Sevastopol bays.
Kalanchoe marmorata Baker
A Tn: Tunisia: Monastir, Monastir city, growing on both sides of the Monastir-Sousse tourist route, 35°46′17″N, 10°42′31″E, 2–3 m, some apparently established subpopulations of few individuals, 30 Nov 2016, El Mokni (herb. El Mokni); ibid., 35°46′08″N, 10°50′22″E, 11 m, escaped individuals from public gardens, 13 Jan 2018, El Mokni (herb. El Mokni); Monastir, Jemmal, 35°37′32″N, 10°45′50″E, 30 m, escaped individuals from cultivated plants, 3 Jan 2018, El Mokni (herb. El Mokni). – Kalanchoe marmorata is native to C and E Africa, where it usually occurs on rocky places at 1200–2400 m. (Darbyshire & al. 2015; APD 2018). It is a very decorative plant due to the marbled leaves and especially its large white flowers, often cultivated both as an ornamental and as a medicinal plant (Descoings 2003). No previous data about the occurrence of this taxon in Europe are available. The present report as a casual alien is therefore the first for the flora of N Africa and the Mediterranean region (according to Marhold 2011a; APD 2018; IPNI 2012+; WCSP 2019).

Kalanchoe sexangularis N. E. Br. var. sexangularis
A Tn: Tunisia: Bizerte, Bizerte city, 37°16′26″N, 09°52′27″E, 5 m, escaped individuals originating from cultivated plants, 26 Jul 2017, El Mokni (herb. El Mokni); Mahdia, Baghdadi, growing on both sides of the Monastir-Sousse tourist route, 35°34′32″N, 11°01′00″E, 8 m, apparently established subpopulation of c. 17 individuals, 30 Dec 2018, El Mokni (herb. El Mokni). – Kalanchoe sexangularis is an evergreen, robust shrub native to S and S tropical Africa: Mozambique, South Africa, Swaziland, Zambia and Zimbabwe (Figueiredo & al. 2016; APD 2018). The species can be propa- gated both sexually by seeds and asexually by simple cuttings (Descoings 2003; Figueiredo & al. 2016). Two varieties, differing in some vegetative and flower characters, are currently recognized within this species according to Figueiredo & al. (2016). The Tunisian specimens are referable to K. sexangularis var. sexangularis in having leaf margins consistently crenate and flowers relatively short, up to 14 mm long. In Europe, K. sexangularis was reported as alien only from NE Spain (Catalonia) by Aymerich & Gustamante (2016). The present report as a casual alien is therefore the first for the flora of N Africa (see Marhold 2011a; APD 2018; IPNI 2012+; WCSP 2019).

Rorippa austriaca (Crantz) Besser
+ Gr: Greece: Nomos of Evros, Eparchia of Orestiada, W outskirts of village of Pentalofos, 41°39′N, 26°11′E, 280 m, locally gregarious on damp roadside, 11 May 2018, Strid & Hartvig 59437 (UPA, herb. Strid). – Not previously reported from Greece (Dimopoulos & al. 2013, 2016). This species is fairly widespread in Bulgaria (Assyov & al. 2006: 327) and is also known to occur in adjacent European Turkey (Davis 1965: 431). Hence the collection simply represents an expected regional extension of the distribution range.
Carex canariensis Kük. – Fig. 2.
+ Md(M): Portugal: Madeira, Encumeada, Caminho Real da Encumeada, near water station, 32°44′50.1″N, 17°00′55.5″W, c. 800 m, laurisilva patch with some planted Eucalyptus trees, 2 Jun 2018, BenítezBenítez 69CBB18, Míguez & Sequeira (UPOS 10728). – Since its description, Carex canariensis has been considered endemic to the Canary Islands (Kükenthal 1900; Jiménez-Mejías & Luceño 2011; Govaerts & al. 2018+), and has remained unreported from other Macaronesian archipelagos (Azores: Silva & al. 2005; Cabo Verde: Govaerts & al. 2018+; Madeira: Jardim & Menezes de Sequeira 2008). Its native status in Madeira still has to be elucidated, although the habitat of the single population we have found (a patch of laurisilva forest) suggests that it is presumably native. Carex canariensis could have been confused with C. divulsa Stokes or C. pairae F. W. Schultz (= C. muricata subsp. lamprocarpa auct.) in Madeiran floras (Menezes 1914; Press 1994) although these two species can be easily distinguished from C. canariensis by several morphological characters (see Luceño 2008; Molina & al. 2008): leaf size (usually more than 4 mm wide in C. canariensis vs up to 3.5(–4.3) mm wide in C. divulsa and C. pairae), inflorescence morphology (longer, paniculate and conspicuously branched in C. canariensis vs shorter, spicate, unbranched, or branched only at base in C. divulsa and C. pairae), and utricle appearance (ovoid to ovoid-lanceolate, conspicuously nerved on proximal half in C. canariensis vs ovoid-elliptic to elliptic and nerveless to faintly nerved at base in C. divulsa and C. pairae). Therefore, a thorough revision of herbarium specimens (in local Madeiran herbaria or in other herbaria known to include important Madeiran collections such as BM and K) could result in a wider distribution of C. canariensis in Madeira, with historical collections possibly supporting a native status. This would be the 12th native Carex species reported for the Madeiran archipelago (Jardim & Menezes de Sequeira 2008; Govaerts & al. 2018+). Although the collected specimens were rather immature, the morphology of the Madeiran plants agrees fairly well with its identification as C. canariensis after comparison with representative collections and high-resolution pictures of the type material. Moreover, we have preliminarily assessed its identity and phylogenetic relationships with the Canarian populations based on molecular data (in prep.). This finding involves a remarkable extension of the range of C. canariensis, because it was believed to be entirely confined to the Canary Islands archipelago (reported from all main islands except for the arid, easternmost Lanzarote and Fuerteventura; Jiménez-Mejías & Luceño 2011), found at a distance of c. 500 km to the south of Madeira. A considerable colonization capacity by long-distance dispersal in Carex has been suggested to explain its presence in oceanic archipelagos, including Macaronesia, where the genus is represented by a number of native species, several of them island endemics (Escudero & al. 2009; Jiménez-Mejías & Luceño 2011; Govaerts & al. 2018+). According to IUCN criteria, C. canariensis has been considered Vulnerable (VU) in the Red List of Spanish vascular flora (Moreno 2010), due to a reduced area of occupancy, severely fragmented populations, and extreme fluctuations in the number of mature individuals. The conservation status of the Madeiran population of C. canariensis reported here should be evaluated because it is the only occurrence of the species there so far.

Carex reuteriana subsp. mauritanica (Boiss. & Reut.) Jim. Mejías & Luceño – Fig. 3.
+ Lu: Portugal: Alentejo, Baixo Alentejo, Beja district, between Paymogo (Huelva, Spain) and Vales Mortos, international bridge over Chanza river, 37°45′37.44″N, 7°24′45.67″W, 90 m, river shore, on quartzites, with dispersed Fraxinus angustifolia Vahl, Alnus glutinosa (L.) Gaertn., Flueggea tinctoria (L.) G. L. Webster and Nerium oleander L., surrounding landscape of Cistus ladanifer L. scrubland derived from deterioration of Quercus rotundifolia Lam. forest, 21 May 2018, BenítezBenítez 36CBB18 & MartínBravo (UPOS 10727). – Carex reuteriana is an Ibero-N African endemic belonging to Carex sect. Phacocystis Dumort. It is distributed in the W Iberian peninsula and NW Africa (Luceño & Jiménez-Mejías 2008; Jiménez-Mejías & al. 2011). It includes two allopatric subspecies, the type subspecies from the C-NW Iberian peninsula (Spain and Portugal), and C. reuteriana subsp. mauritanica from the SW Iberian peninsula and a few isolated populations in NW Africa (N Morocco and NW Algeria; see maps in Jiménez-Mejías & al. 2011; Benítez-Benítez & al. 2018a). Both grow in creeks and river shores at low and medium altitudes; the type subspecies is acidophilous, while C. reuteriana subsp. mauritanica is indifferent to the substrate. This is the first record of C. reuteriana subsp. mauritanica for Portugal; it was found on the Portuguese shore of a river which serves as natural border between Spain (Huelva province) and Portugal (Beja district). The taxon apparently reaches Portugal very marginally, and it appears to be substituted by the close C. elata All. subsp. elata in most of S Portugal (Jiménez-Mejías & al. 2007; Rodríguez-González & al. 2010; Benítez-Benítez & al. 2018b).

Hypopitys monotropa subsp. hypophegea (Wallr.) Tzvelev (≡ Monotropa hypophegea Wallr. ≡ Hypopitys hypophegea (Wallr.) G. Don)
+ AE(G): Greece: East Aegean Islands, Nomos of Lesvos, Eparchia of Mitilini, Island of Lesvos, SE of Agiasos near Sanatorion, 39°03′50″N, 26°23′36″E, c. 660 m, Castanea sativa forest on schist, 12 Jun 2017, Chiotelis (ATHU). – The genus Hypopitys is represented in Greece with two subspecies, H. monotropa subsp. monotropa and H. monotropa subsp. hypophegea, the latter recorded so far only from the N Greek mainland (Dimopoulos & al. 2013: 91). This seems to be the first record of Hypopitys from Lesvos, the floristic region of the East Aegean Islands, and the Aegean Archipelago as a whole (the taxon was not mapped in Strid 2016). The cited material belongs to H. monotropa subsp. hypophegea. The parasitic species seems to be very local on Lesvos, restricted to a small area above Agiasos. However, its presence in more localities on the island with suitable habitat conditions is not unlikely.

Euphorbia esula subsp. tommasiniana (Bertol.) Kuzmanov
+ Gr: Greece: Thraki, Nomos of Evros, Eparchia of Orestiada, 6 km NNE of Orestiada, 41°33′N, 26°34′E, 30 m, wet roadsides in agricultural area, 7 May 2018, Strid & Hartvig 59221 (UPA); ibid., Eparchia of Didimotichon, by Erythropotamos river SSE of village of Ellinochorio (W of Didimoticho), 41°22′N, 26°27′E, 50 m, 11 May 2018, Strid & Hartvig 59397 (herb. Strid). – Not previously reported from Greece (Dimopoulos & al. 2013, 2016). A regional extension of the range for this taxon, which is known from adjacent former Yugoslavia, Bulgaria and Turkey (Govaerts & Radcliffe-Smith 2000: 723). Taxonomy and nomenclature as currently adopted in Euro+Med (2006+) is followed here only with reservation. According to recent typification works and evaluations of morphological characters in the E. esula group (Reichert & al. 2018), E. saratoi Ard. has been identified as the correct name at species level for the taxon under discussion here (≡ E. esula subsp. saratoi (Ard.) P. Fourn.), while E. tommasiniana Bertol. in the original sense (Bertoloni 1842: 78–79) is supposed to be endemic to the karstic area around Trieste in NE Italy and W Slovenia. Flora of Turkey (Radcliffe-Smith 1982: 623) used the name E. virgata Waldst. & Kit., which is equally inapplicable.
Euphorbia glyptosperma Engelm. (≡ Chamaesyce glyptosperma (Engelm.) Small) – Fig. 4.
A Cm: Crimea: Dzhankoyskiy district, railway station Solenoe Ozero, 45°53′00″N, 34°26′57″E, 12 m, on railway tracks, 2 Oct 2011, Svirin (photo). – Euphorbia glyptosperma is native to North America, where it is widely distributed. As an alien species, it is indicated for some regions of South America (Peru) and W Asia (Caucasus, Russia) (Govaerts & al. 2019; Geltman & Medvedeva 2017). However, the main area of its introduction is Europe, where E. glyptosperma has been known since the beginning of the 20th century. This species is currently listed for at least 11 countries of Europe: N (Sweden), C (Austria, Belgium, Hungary, Netherlands, Switzerland), SW (France, Spain) and SE (Italy, Romania, Republic of North Macedonia) (DAISIE 2008+; Somlyay 2009; Geltman & Medvedeva 2017; Randall 2017; Sîrbu & Şuşnia 2018). In E Europe, E. glyptosperma was introduced in the 1980s, but was correctly identified only recently. Now it is recorded in a number of regions in SE European Russia (Geltman & Medvedeva 2017). For Crimea, this species was not previously cited (Yena 2012; Bagrikova 2013). There are no herbarium vouchers of this species in YALT and MW.
A small population of Euphorbia glyptosperma was found by S. Svirin in 2011 in the north of the Crimean peninsula in the Prisivashe area in an anthropogenic habitat. Initially, the plant was incorrectly identified as E. maculata L. or E. chamaesyce L. Unfortunately, no herbarium specimens were prepared, but the photos allow us to diagnose this record as E. glyptosperma. The species is characterized by morphological features as follows: plant somewhat ascending, completely glabrous; leaves elongate, 2–4 × as long as wide, asymmetric at base, often slightly curved; stipules linear-subulate, fringed or lobed; glands red to purple, with small, white or pinkish appendages; styles very short; seeds oblong-ovoid, apiculate, sharply angular, 1–1.4 mm long, with 3 or 4(–6) prominent, transverse ridges. It differs from E. chamaesyce in ascending shoots, shape of leaves and stipules, smaller, reddish glands and appendages, shorter styles, and seed surface structure; and from E. maculata in complete lack of pubescence, and seeds with more prominent surface sculpturing. Euphorbia glyptosperma has arrived to N Crimea probably by rail and might possibly be found in other parts of the region.

Euphorbia prostrata Aiton (≡ Chamaesyce prostrata (Aiton) Small ≡ Tithymalus prostratus (Aiton) Samp.)
A Cm: Crimea: Yalta vicinity, Nikita, Nikitsky Botanical Garden, Nizhniy Park, Palm Alley, 44°30′32.00″N, 34°14′02.60″E, 105 m, shaded flower bed under regular watering, 19 Jul 2018, Ryff (YALT). – Euphorbia prostrata is native for North and South America. It is widely distributed as an alien plant in many tropical, subtropical and temperate regions of the world (Randall 2017; Govaerts & al. 2019+). The first occurrence of E. prostrata in Europe was observed in the early 19th century in France, then in Italy, Portugal and Spain. Currently, it has spread to C, SW and SE Europe (Bátori & al. 2012; Randall 2017; Govaerts & al. 2019+). Recently, E. prostrata has been recorded in several countries of SE Europe (Bulgaria, Hungary, Romania, Serbia) (Anastasiu & Negrean 2008; Bátori & al. 2012; Vladimirov & al. 2014; Veljić & al. 2017). However, this species was not known for E Europe (Geltman 2012b) until it was found in Moldavia in 2014 (Izverscaia & Ghendov 2017). According to the herbarium material at YALT and to recent publications (Yena 2012; Bagrikova 2013), E. prostrata has not been collected previously in the Nikitsky Botanical Garden and in Crimea at all. Therefore, it is the first record of this alien species for the Crimean peninsula and the second one for E Europe. This floristic finding confirms an actual expansion of E. prostrata to the east. It has not yet been cited for the Caucasus (Geltman 2012a), so Crimea can be considered the current eastern border of its distribution area in Europe and the N Black Sea region.
Euphorbia prostrata is characterized by capsules hairy on the keels only and seeds usually less than 1 mm long, sharply angled, with 5–8 narrow, sharp, slightly irregular, transverse ridges (Pahlevani & Akhani 2011; Pahlevani & Riina 2011; Berry & al. 2016). It differs from the closely related E. chamaesyce L. in capsule indumentum and seed surface structure; and from E. glyptosperma Engelm. in leaf shape, pubescent capsules and somewhat smaller seeds with narrower, sharper ridges. So far, only one population of E. prostrata with no more than 50 individuals has been recorded in the Nikitsky Botanical Garden. However, it can be assumed that this species is more widely distributed in Crimea.

Not mentioned for Greece by Dimopoulos & al. (2013, 2016) or from adjacent Balkan countries (Valdés & Scholz 2009; Barina & al. 2018). In N Greece obviously preferring acidic soil of open places in Erica manipuliflora heathland on granite and gneiss. Numerous individuals were found in any mentioned locality. Our collections corroborate a phytosociological record of the species from E. manipuliflora heathlands further east between Mikro Tympano and Semeli (Nomos of Xanthi, W Thraki) which, however, was not substantiated by herbarium specimens (Theodoropoulos & al. 2011: 10, Table III). A 19th century report from Peloponnisos by Gittard (in herb. Fauché) was definitely considered erroneous by Boissier (1884: 527–528, under Aira globosa Thore; see also Halácsy 1904: 365–366; Hayek 1932: 328).

Desf. and P. viridis (Gouan) Breistr. (Tzvelev 1976; Valdés & al. 2009+; Yena 2012). This is the first report of P. maritimus for the region. In E Europe it was earlier reported for the Lower Volga area (Tzvelev 1976). This species is widespread as native in the Mediterranean, extending to the E and S Caucasus (Tzvelev 2006; Valdés & al. 2009+). Polypogon maritimus is known as an alien and a weed in many countries of several continents (Randall 2017). The only locality in Crimea with a small population of P. maritimus was found near Balaklava. Further searches and monitoring are necessary to establish native or alien status of this species in the region.

Soc. 64: 381. 1971 ≡ Clinopodium bulgaricum (Velen.) Melnikov in Turczaninowia 19(2): 90. 2016.
Micromeria dalmatica Benth. was described from Kotor in S Dalmatia (for lectotypification, see Melnikov 2015: 106), based on a collection published by Visiani (1830: 51) under Thymus origanifolius Vis. nom. illeg. (antedated by T. origanifolius D. Don 1825 from W Himalaya). Similar plants from S Bulgaria, first described as M. origanifolia subsp. bulgarica Velen. (Velenovský 1899), were subsequently recombined as M. dalmatica subsp. bulgarica (Velen.) Guinea (Heywood 1971: 381). This subspecies occurs also in NE Greece (see, e.g., Rechinger 1939; Kitanov 1943; Quézel & Contandriopoulos 1968; Eleftheriadou & Raus 1996) including the island of Thasos (Chilton 1997, 2003). Tutin & al. (1972: 168) recognized M. dalmatica with subsp. dalmatica in “C Jugoslavia” (more precisely what is now SW Croatia and Montenegro, see map in Silić 1979: 190) and subsp. bulgarica in S Bulgaria and NE Greece (additionally extending to the Republic of North Macedonia, see Silić l.c.). Chorological separation, combined with differences mainly confined to indumentum characters of the two taxa, makes subspecific rank appropriate. It has recently been demonstrated that M. dalmatica and related species are better placed in Clinopodium than in Micromeria (Bräuchler & al. 2006, 2008; Melnikov 2015, 2016). However, the southeastern subspecies of M. dalmatica has not been recombined under Clinopodium as yet. Vandas (1905, 1909, under M. bulgarica) raised C. dalmaticum subsp. bulgaricum to species rank (followed by Silić 1979 and Greuter & al. 1986: 330) which, however, has not been adopted in any subsequent Bulgarian basic flora (Stojanov & Stefanov 1925: 958; Stojanov & al. 1967: 924; Jordanov 1989: 359; Andreev & al. 1992: 482; Assyov & al. 2006: 257). On the other hand, treating C. dalmaticum subsp. bulgaricum as a mere synonym of C. dalmaticum (Euro+Med 2006+, based on Bräuchler 2009 and followed by Dimopoulos & al. 2013) does essentially hide extant chorological and morphological information and seems therefore not recommendable.

Native to southern Africa (Angola to Mozambique, Barnes & al. 1996: 6–10), armed with distinctive, in Algeria usually c. 7 cm long, white, paired stipular thorns, which means that the shrub to medium-sized tree must be approached carefully. Seedlings and saplings are found in urban areas and suburbs of Algiers, where the species is locally naturalized, generated by seeds produced by certainly not deliberately planted individuals. It has recently been demonstrated that the recognition of at least five genera in the polyphyletic Acacia Mill. s.l. is inevitable, and the African taxa are better placed in the two reinstated genera Senegalia Raf. and Vachellia Wight & Arn. Accordingly, the name Vachellia karroo applies for the xenophytic species under discussion here (Kyalangalilwa & al. 2013: 513–514).

It has tiny seeds, which are easily spread by birds, bats and rodents and are capable of germinating almost anywhere they land (GISD 2015). It is a widely planted and popular ornamental tree that has been introduced to many tropical, subtropical and warm-temperate regions around the world (Dehgan 1998; Rauch & Weissich 2000; Burrows & Burrows 2003; Van Noort & Rasplus 2018). In the Mediterranean area, the taxon is cited for few countries, as naturalized in Sicily, the Canary Islands including Gran Canaria and as adventitious in Malta and Tenerife (Uotila 2011; Verloove & Reyes-Betancort 2011). For N Africa, the species is listed only as cultivated for Morocco, Libya and Egypt (APD 2018). For Tunisia, this is the first record as a casual (probably ornithochorous) alien.

For status assessment of Bougainvillea glabra in Algeria we share the opinion of Barina & al. (2013: 177), who reported the species in Albania as a remnant of earlier plantings in natural habitats, thereby stating that there are no reports on its naturalization with spreading populations in Mediterranean countries so far. In Macaronesia, however, the species is given as established in the Canary Islands of La Gomera and Gran Canaria (Euro+Med 2006+; Arechavaleta & al. 2010: 127).

This taxon was described from La Graciosa, Canary Islands (Webb in Webb & Berthelot 1845), and the lectotype was designated by A. Santos (FI000239! without date). Phelipanche gratiosa differs from P. ramosa (L.) Pomel s.str. and P. mutelii (F. W. Schultz) Pomel s.l. [incl. var. nana (Noë ex Reut.) Uhlich & Rätzel] at first sight by the taller and more robust habit, to 40 cm tall (vs to c. 20 cm tall, rarely taller), the larger corolla, (15–)19–27 mm long (vs 8–18[–20] mm long), the richly flowered spike, very dense and compact in the distal two thirds (vs spike typically lax in full flower and rather few-flowered). The most common host is the dwarf shrub Launaea arborescens; rarely have other Asteraceae been observed as hosts as well (Reichardia tingitana (L.) Roth and Urospermum picroides (L.) Scop.). By contrast, L. arborescens is not known as a host for P. ramosa or P. mutelii. For more diagnostic characters of those and other Phelipanche species, see the table in Rätzel & al. (2017: 660ff).

Wildpret trees, 1 Nov 2017, El Mokni (photo). – Native to Japan and China, Pittosporum tobira is an evergreen shrub easily recognizable by its clusters of extremely fragrant, creamy white flowers during late spring. This taxon was listed as highly invasive in Italy, Sicily and Spain (cf. Dana & al. 2001; Sanz-Elorza & al. 2001; Celesti-Grapow & al. 2016), whereas for France, Portugal and Sardinia it is reported as alien with unknown status (Marhold 2011b). For N Africa, the taxon was only reported from Libya as cultivated on a large scale (Marhold 2011b; APD 2018). This is the first record from Tunisia as a local, possibly ornithochorous, casual escape from cultivation.

(Verloove 2008). In Europe, the taxon has been reported as casual or naturalized alien in Italy (see, e.g., Ardenghi & al. 2011; Galasso & al. 2018), Spain (Verloove 2008) and Corsica (Valdés 2012+). For N Africa, the species is listed only from Tunisia as a casual alien (Valdés 2012+; Ardenghi 2017; APD 2018). Many populations, sometimes with hundreds of individuals, have been observed since 2015, and they have been occupying more and more space mainly in C and N Tunisia due to the plentiful production of fruits and seeds from July to January. Therefore, the actual status of this taxon in Tunisia is re-defined here as fully naturalized.

A Tn: Tunisia: Sousse, Mohamed V, near railroad track leading to Sousse Bab-Jdid station, only three individuals very close to walls of old buildings, 26 Jan 2019, El Mokni (photo). – Citharexylum spinosum is native to the Caribbean (Turner & Wasson 1997). It is cultivated in warm regions of the world as an ornamental for its fragrant, white flowers and attractive foliage. The wood is sometimes used in cabinetry (Turner & Wasson 1997). This taxon was documented as naturalized on O‘ahu, Hawaiian Islands (Herbarium Pacificum Staff 1998), where it has a proven ability to invade native ecosystems in the Ko‘olau Range. In the same Islands, on Maui, C. spinosum has spread from plantings and is naturalized in Haiku, Kihei and Lahaina (Starr & al. 2002). Within the Mediterranean area, it was until now known only from Tunisia as cultivated (APD 2018). Therefore, this citation as a casual alien, almost certainly dispersed by fruit eating birds, constitutes the first report of the species for the Tunisian flora, N Africa and the Mediterranean area outside cultivation.

Parthenocissus quinquefolia (L.) Planch.
A Tn: Tunisia: Bizerte, Bizerte city, epiphytic individuals on planted Melia azedarach L. trees on roadsides, 11 Jun 2014, El Mokni (photo). – Native to C and E North America south to Mexico, Parthenocissus quinquefolia is a woody, deciduous, vigorous, tendril-climbing vine that grows rapidly with no need of support as it clings to all types of surfaces due to its adhesive holdfasts located at the tendril ends. Its greenish white flowers give way to a high number of blue-black berries that are searched for and eaten by birds in autumn. Introduced as an ornamental, it has escaped from gardens to become naturalized and listed as invasive in several European countries (Ardenghi & al. 2017; DAISIE 2017; GRIIS 2017), China (Chen & Wen 2007) and Cuba (Oviedo Prieto & al. 2006: 49; Oviedo Prieto & González-Oliva 2015: 32) and regarded as an environmental weed in Australia (Weeds of Australia 2017). In N Africa, the taxon is reported as a naturalized alien only in Algeria (Zeddam & Raus 2010). Therefore, this citation as a casual alien constitutes the first report for the Tunisian flora as a local escape from cultivation, probably disseminated by birds.
