Amaranthaceae

Alternanthera tenella Colla

A Si(S): Italy, Sicily: Palermo city, Via Paolo Balsamo, 38°06′6″N, 13°22′06″E, 22 m, public flowerbed adjacent to new tram line, 21 Dec 2015, Scafidi (PAL 102712). — Alternanthera tenella is indigenous in large parts of the New World (Clemants 2003) and has invaded some tropical regions of the Old World (Robertson 1981; Eliasson 1987). In Europe, it has been recorded as a casual alien in Belgium (Verloove 2006). In Italy, a single specimen from the beginning of the 20th century, collected by A. Fiori in Florence, identified by Iamonico (2011) as A. sessilis (L.) DC. and later revised as A. tenella (Iamonico & Sánchez-del Pino 2014, 2015), indicates the historical occurrence of this species in Italy.

Amaranthus palmeri S. Watson

N Tu(A): Turkey: İzmir: İzmir-Çanakkale main road, between Menemen and Yeni Foça, Helvacı village, 16 m, margin of cornfields, populations with male and female plants, 20 Sep 2015, Doğan 23/2015 & al.

(obs.); Adana: Ceyhan, Mustafabeyli village, 25 m, 22 Jul 2014, Doğan 36/2014 & al. [pistillate specimen] (AYDN); ibid., 22 Jul 2014, Doğan 37/2014 & al. [staminate specimen] (AYDN); Osmaniye: Toprakkale, 120 m, roadside, 23 Jul 2014, Doğan & al. (obs.); Hatay: Erzin, 160 m, field margins, 19 Aug 2014, Doğan & al. (obs.). — In recent field surveys, we found Amaranthus palmeri for the first time in Turkey. This species is native to North America (Sauer 1955), but it has greatly expanded its range, becoming one of the most economically damaging glyphosate-resistant (Beckie 2011) invasive species in many parts of the world. Recently, it has also been recorded from N Italy (Iamonico & al. 2015). The species also occurs in most neighbouring countries, e.g. Greece (Raus & Raabe 2006; Strid 2016a, b), Cyprus (Hadjikyriakou & al. 2004) and Israel (Danin 2004). Amaranthus palmeri is the type species of A. sect. Saueranthus Mosyakin & K. R. Robertson, which includes three more dioecious species: A. arenicola I. M. Johnst., A. greggii S. Watson and A. watsonii Standl. The members of A. sect. Saueranthus are characterized by 5 (rarely 4) spathulate tepals (2–3.5 mm long, apex rounded, truncate or acuminate) and usually dehiscent fruits (Mosyakin & Robertson 1996). Amaranthus palmeri can easily be distinguished from other amaranths in Turkey by the sectional characters mentioned above. In addition, its dioecious habit, long petioles, which often exceed the length of leaf blade, long terminal spikes, and spiny tipped bracts (in female plants), which are much longer than the tepals, can be helpful for its recognition. For a full description of A. palmeri see Mosyakin & Robertson (2003).

In Turkey, Amaranthus palmeri was certainly introduced by humans, probably by contamination of imported seeds or animal manures. So far, this species is known only from İzmir, Adana, Osmaniye and Hatay provinces, where it has become naturalized, but it may have been overlooked in other parts of Turkey as well. The abundance and ecological impacts of some invasive plant species are much greater in their non-native ranges than in their native ranges (Hierro & al. 2006, 2013). Our preliminary field observations showed that this species is an extremely aggressive, fast-growing species that has the potential to occupy large areas in Turkey. Therefore, the spread of this species, its potential impacts on agriculture and natural vegetation and its resistance to herbicides should be explored in Turkey, too. Since hybridization among different species has been widely reported within Amaranthus (Sauer 1955), future investigations should also concentrate on detecting possible hybrids of A. palmeri with other species in Turkey. Amaranthus palmeri hybridizes more readily with A. spinosus L. than with other amaranth species (Gaines & al. 2012). Therefore, the hybrid of A. palmeri and A. spinosus should be looked for in Adana, where both species occur. The new record brings the total number of Amaranthus species known from Turkey to 15, including two hybrids (Aellen 1967; Tug 2012).

Asparagaceae (incl. Hyacinthaceae)

Drimia glaucophylla (Bacch., Brullo, D'Emerico, Pontec. & Salmeri) Raus, comb. nov.Charybdis glaucophylla Bacch., Brullo, D'Emerico, Pontec. & Salmeri in Phytotaxa 69: 18. 2012.

For this SW Sardinian endemic squill recently named under Charybdis Speta (Bacchetta & al. 2012), a name in Drimia Jacq. is required, because, according to Euro+Med (2006+), the inclusion of the former into the latter applies — a taxonomic concept followed by, e.g., Dimopoulos & al. (2013) and Hand & al. (2015+).

Callitrichaceae (Plantaginaceae s.l.)

Callitriche hermaphroditica L. subsp. hermaphroditica

+ Fe: Finland: South Häme, Hattula, Lake Lehijärvi, E shore, eutrophic clear-watered lake, shallow water, sand bottom, grid 27°E 6773:356, 9 Sep 1985, Uotila 34697a (H 717326); Sodankylä Lapland, Sodankylä, Sattanen, Kitinen River, 17 Aug 1927, Cajander (H 396654).

Schotsman (1958) paid attention to the considerable variability of the fruits of Callitriche hermaphroditica and to its large, broad-winged fruits in the N part of its area. Martinsson (1991) pointed out that the fruit size variation in C. hermaphroditica has a clear geographical pattern in Nordic countries: plants with large fruits are found in the northernmost parts as well as in brackish waters of the gulfs of Bothnia and Finland, and plants with small fruits are found in S Denmark, Sweden, Norway, Finland and adjacent Russia. As to the plants with large fruits, both Schotsman and Martinsson referred to Hegelmaier's (1867) C. autumnalis L. ß [var.] macrocarpa, but they did not draw taxonomic conclusions from their observations. Lansdown (2006, 2008) studied this variation mainly in the British Isles and recognized plants with large fruits and broad wings as C. hermaphroditica subsp. macrocarpa, which he found to have a more northern distribution than C. hermaphroditica subsp. hermaphroditica. Karlsson & Agestam (2013) accepted both subspecies for Sweden. Tzvelev (1997) also realized the existence of two taxa with different wings of fruits and some differences in ecology and distribution in NW Russia, but named the narrow-winged one C. hermaphroditica subsp. exalata Tzvelev and the broad-winged one C. hermaphroditica subsp. hermaphroditica. The subspecific treatment following Lansdown is accepted in Euro+Med PlantBase. Based on herbarium specimens in H, the presence of both subspecies is confirmed for some Nordic and Russian territories.

Caryophyllaceae

Sagina apetala Ard.

N Cm: Crimea: Simferopol, Kuybysheva Square, 7 Aug 2007, Yena (CSAU); Sevastopol, 11 Apr 2014, Svirin (CSAU); Balaklava, Naberezhnaya Str., 21 Apr 2014, Ryff (YALT); Yalta, Chekhova Str., 26 May 2010, Ryff (YALT); Nikitsky Botanical Garden, 4 Jun 2013, Bagrikova (YALT); Gurzuf, 2 Jul 2011, Ryff (YALT); Alushta, bus station, 11 May 2014, Ryff (YALT); Feodosiya, Naberezhnaya Str., 8 Jun 1996, Yena (CSAU); all between concrete slabs. — Adventive for Crimea in cities and towns of the Crimean foothills and the S coast. This species is restricted to places paved with slabs, where it often grows together with Sagina procumbens L. Sagina apetala may have arrived at those localities together with the sand that is put as a base layer under slabs. Altogether, three species of Sagina are now known in Crimea, only S. maritima Don being indigenous (Yena 2012).

Telephium orientale Boiss. (= Telephium imperati subsp. orientale (Boiss.) Nyman)

+ Rf(CS): Russia: Dagestan, Akhtynsky District, near village of Midzhakh, left bank of river Akhtytchai, 1600 m, dry stony slopes, 16 Aug 2013, Murtazaliev (DAG, LE). — New to Russia. Only a few specimens of Telephium orientale were found in this locality, which is at the N border of its geographical range. The nearest occurrences of this species are in the NE part of Azerbaijan.

Chenopodiaceae

Patellifolia procumbens (C. Sm.) A. J. Scott & al. (=Beta patellaris Moq. = Tetragonia pentandra Balf. f.)

+ Tn: Tunisia: Monastir, 35°46′3″N, 10°46′8″E, 4 m, ruderal, roadsides, gardens, 16 Jan 2016, El Mokni (HFLA); ibid., 35°46′40″N, 10°48′68″E, 26 m, El Mokni (HFLA). — As part of the ongoing revision of the family Amaranthaceae s.l. in Tunisia (see, e.g., Sukhorukov & al. 2016), a population identified as Patellifolia procumbens was found in anthropogenic habitats of the Monastir area. Patellifolia procumbens is a W Mediterranean species recorded in Sicily, the Iberian peninsula, the Balearic and Canary islands, the Madeira and Selvagens archipelagos, Morocco, Algeria and Libya (Thulin & al. 2010; Uotila 2011). The recent Catalogue synonymique commenté de la Flore de Tunisie (Le Floc'h & al. 2010), the Index synonymique de la flore d'Afrique du Nord (Dobignard & Chatelain 2011) and the online African Plant Database (African Plant Database 2012) also do not record this species in Tunisia. Our discovery is the first for the flora of Tunisia and is represented by two populations, the first one located on roadsides (town of Monastir) and below some olive trees, while the second one is c. 8 km distant, also in ruderal habitat and on roadsides within halophytic vegetation. Each population occupies an area of about 1 km2 and both are threatened by human activities, mainly the construction of buildings, and biological invasions by exotic species such as Cortaderia selloana (Schult. & Schult, f.) Asch. & Graebn., Gazania rigens (L.) Gaertn., Lantana camara L. and Myoporum insulare R. Br.

Ambrosia psilostachya DC. (= A. coronopifolia Torr. & A. Gray)

A Gr: Greece: Central Makedonia, Nomos of Thessaloniki, Periurban Forest of Thessaloniki “Kedrinos Lofos”, S of village of Exochi, 40°37′35.8″N, 23°01′77″E, 455 m, roadside, 16 Sep 2015, Giannakis (TAUF); ibid., 21 Oct 2015, Giannakis & al. (TAUF); ibid., 17 Nov 2015, Eleftheriadou (TAUF). — A xenophyte originating from North America, introduced to and sometimes naturalized in many countries in Europe (Hansen 1976), Asia (Kazakhstan), Africa (Mauritius) and Australia (Bassett & Crompton 1975; Valkenburg & al. 2015+). It has not been recorded previously from Greece (Dimopoulos & al. 2013) nor from adjacent countries, viz. Albania, the former Yugoslav Republic of Macedonia, Bulgaria and Turkey (Greuter 2006+). Approximately 300 stems were found, which may be produced from one or a few branched rhizomes and therefore can hardly be counted as individuals. According to Fernald (1950: 1470), Greek specimens belong to Ambrosia psilostachya var. coronopifolia (Torr. & A. Gray) Farw. ex Fernald. However, infraspecific variability in A. psilostachya hardly deserves taxonomic recognition (Flora of North America Editorial Committee 2006: 18).

Centaurea kotschyana Heuff.

+ Gr: NC Greece: Central Makedonia, Nomos of Pella, Mt Tzena, 41.151956°N, 22.171624°E, 1930 m, grassy subalpine ledge, parent rock andesite, 31 Jul 2012, Chasapis 2226 (TAUF). — Centaurea kotschyana occurs in Albania, Bosnia and Herzegovina, Bulgaria, Montenegro, Poland, Romania, Serbia and Ukraine (Dostál 1976; Greuter 2006+). It has not been recorded from Greece previously (Dimopoulos & al. 2013). A small population of approximately 50 individuals was found just S of the N border of the country on a steep slope, at an altitude between 1900 m and 2000 m on volcanic substratum. On Mt Tzena, C. kotschyana coexists with the similar C. grbavacensis (Rohlena) Stoj. & Acht. Both species share the dark brownish purple colour of the florets, but are easily distinguished by a combination of stem and leaf characters. Centaurea kotschyana exhibits leafy stems and undivided basal leaves. By contrast, C. grbavacensis has the stem always leafless above and the basally crowded leaves pinnatisect to bipinnatisect, with numerous 3-dimensionally arranged linear or linearlanceolate ultimate segments, so that the habit of the plant is quite similar to a species of Jurinea Cass.

Rhaponticoides razdorskyi (Karjagin) M. V. Agab. & Greuter (≡ Centaurea razdorskyi Karjagin)

+ Rf(CS): Russia: Dagestan, near village of Talgi, on top of left crest of Talginskoe gorge, 450 m, rocky slopes of S exposure, 3 Jun 2010, Murtazaliev (DAG, LE). — New to Russia. It has been considered a local endemic (Aghababyan 2008), growing on the low foothills of the Caucasus in Azerbaijan (near the city of Sumgait, stantsiy Nasosnaja, Mt Ag-Burun). In Dagestan, it was discovered in the suburbs of the village of Talgi, SW of the city of Makhachkala. The population there is quite large, of some 600–700 individuals, and occupies an area of 2–3 km2.

Convolvulus erinaceus Ledeb.

+ Rf(CS): Russia: Dagestan, Chechen Island, 1.5 km NE of village of Chechen, sands, 10 Jun 2011, Teimurov (DAG, LE). — New to Russia. About ten individuals in total were observed in a small area. This is the second locality of Convolvulus erinaceus, a predominantly C Asian species, in the Caucasus region. This species has been recorded earlier from the E Transcaucasian region, the suburbs of the village of Sangachaly in Azerbaijan (Grossgejm 1967). Another species of this genus, new for the Caucasian flora, has been recently detected in Azerbaijan: C. fruticosus Pall. (Karimov & al. 2016).

Crassulaceae

Crassula multicava Lem. subsp. multicava Fig. 1.

N Lu: Portugal: District of Lisboa, Sintra, Parco de Palácio Nacional de Pena, 450 m, widely naturalized under forest along path to Palácio, 26 Jul 2016, Gallo GL-8578 (FI). — A South African species, new for continental Portugal (not given in Castroviejo 1997; Euro+Med 2006+; Menezes de Sequeira & al. 2011; Dominguez de Almeida & Freitas 2012; Sociedade Portuguesa de Botânica 2012–2016), naturalized in the same habitat with Aichryson laxum (Haw.) Bramwell. Its spread is favoured by the breaking-off of branches, which root very easily, and by the adventitious buds that develop in the axils of the bracts (Toelken 1977: 208). Crassula multicava is widely naturalized in California, U.S.A. (Kartesz 2015), New Zealand (Breitwieser & al. 2016), Australia (Atlas of Living Australia 2016+), the Azores (Universidad dos Açores 2008+), Madeira (Euro+Med 2006+), the Canary Islands (Sanz Elorza & al. 2004; Gil González 2015), Spain (Laguna Lumbreras & al. 2014) and Britain, on the Isles of Scilly (Botanical Cornwall Group 2012: photo at  http://www.botanicalcomwall.co.uk/isles-of-scilly/), where it has not been previously reported (cf. Clement & al. 2005; DAISIE 2008+; Stace 2010; BSBI & BRC 2016).

Cruciferae (Brassicaceae)

Cochlearia danica L.

+ Hu: Hungary: Biharkeresztes, roadside verge of E60 (only 7 km from Romanian border), 47.13529°N, 21.69858°E, abundant, 29 Mar 2016, Molnár V. & Löki (DE). — No previous records are known from Hungary. The spread of this salt-tolerant, coastal species along motorways and trunk roads in Europe has been widely observed during the last decades, e.g. in Germany (Dunkel 1987), Belgium and the Netherlands (Mennema 1986; Koch 1996), Scotland (Welch 2001) and Austria (Hohla & Raabe 2012). The discovery of more populations both in Hungary and Romania is to be expected.

Elatinaceae

Elatine hexandra (Lapierre) DC.

— Hu: The first record of Elatine hexandra in Hungary, from the surroundings of Tokaj (NE Hungary), was given by Hazslinszky (1866). After that, national floras (e.g. Jávorka 1925; Simon 1992) as well as European works (Cook 1968; Uotila 2009) have indicated this taxon as present in Hungary. Duplicates of the voucher specimen collected by Hazslinszky in Tokaj are stored in B, BP and PRC. There is one more specimen in BP (“com. Szatmár, in Oryzetis ad Kölcse”, 9 Oct 1959, Boros) determined as E. hexandra. All these sheets represent shoots with 3-merous flowers, with 3 stamens and short (<3 mm) pedicels. Hazslinszky's specimen in BP was revised by G. Moesz in 1908 as E. ambigua Wight; on the other hand, the duplicate in PRC was erroneously confirmed as E. hexandra by J. Prančl in 2014. The specimen collected by Boros was revised as E. cf. ambigua by P. Uotila in 2010. However, the above-mentioned characters suggest that all those specimens belong to the terrestrial form of E. triandra Schkuhr, as defined by Molnár Veszprém (2009). Despite intensive field surveys (Molnár Veszprém & Pfeiffer 1999) and revision of herbarium material (B, BP, BPU, BRA, DE, PR, PRC, SAV and W), no findings of E. hexandra from Hungary have been revealed; we therefore suggest to exclude E. hexandra from the flora of Hungary.

It is a new species for the flora of the Volga basin, where it reaches its W limit of distribution. Iris glaucescens is sometimes erroneously included as a synonym in the NW Caspian lowland endemic species I. scariosa Willd. ex Link (Shevchenko & Rodionenko 2008).

The genus Brachychiton Schott & Endl. (bottle-tree) is cultivated for ornament outside Australia for its habit, bark, foliage, and showy trusses of brilliantly coloured flowers (Huxley & al. 1992). Brachychiton discolor and B. diversifolius are two Australian (Queensland and New South Wales) trees (Huxley & al. 1992) widely used as ornamentals in Sicily. No previous records of naturalization for Italy or Sicily have been found in relevant standard sources (from Bertoloni 1854 to Celesti-Grapow & al. 2010). The newly discovered juvenile individuals (at least two years old) in the city of Palermo, where different species of Brachychiton are commonly used for ornament, have originated by dissemination of cultivated plants along Archirafi street.

Proboscidea louisianica (Mill.) Thell.

A Gr: Greece: Peloponnisos, Nomos of Argolis, Eparchia of Nafplio, SSW of Arachneo alongside road to Gatzia, 37°40′19″N, 22°56′54″E, 570 m, scattered individuals in cereal fields, 24 Oct 2015, Raabe (MSTR 163398). — This is the first confirmed record for Greece of this xenophyte of North American origin. A previous report from the East Aegean island of Lesvos (Hecht-Markou 1999) turned out to refer to misidentified plants of Ibicella lutea (Lindl.) Van Eselt. (Yannitsaros & Bazos 2001). When the infraspecific taxonomy of Bretting (1983) is adopted, the Greek population can be allocated to Proboscidea louisianica subsp. louisianica. By the end of October the plants were in flower, some of them already exhibiting young fruits, but it is not known whether the fruits mature under the prevailing agricultural impact. The dry, hooked fruits of P. louisianica attach to animals and may disperse by means of zoochory. The above-cited locality previously harboured a rich flora of cereal weeds including rare species such as Silene longipetala Vent, (see Strid & Tan 1997: 260 & map 495). The plant diversity there is now rapidly declining due to intensive application of commercially supplied fertilizer and grazing by sheep and goats. The original source of the seeds of the Greek population of P. louisianica may be imported forage from the United States, where it is also found in pastures and as a weed of fields, in particular of cotton. It is resistant to many herbicides used in cotton, and control options include hoeing by hand (Riffle & al. 1988). The latter method is also reported for the control of Ibicella by local farmers on Les vos island (Hecht-Markou 1999: 76). Proboscidea louisianica is introduced elsewhere in the Euro+Med area and is for the most part established in Portugal, Spain, S France, Italy, S Russia and Caucasia (Czerepanov 1995: 315; Greuter & al. 1989: 240; Paiva & al. 2001: 24).

(Munz 1965: 187), have been recorded in Greece. Oenothera lindheimeri, in horticulture better known under its synonym Gaura lindheimeri, is now placed within Oenothera sect. Gaura (L.) W. L. Wagner & Hoch based on recent molecular findings (Hoggard & al. 2004; Wagner & al. 2007). It is nowadays frequently cultivated as an ornamental in many European countries, and there are several records of escapes from cultivation. It was recently reported from Portugal (Verloove & Sánchez Gullón 2012), Spain (Sánchez Gullón & Verloove 2015) and Belgium (Rostański & Verloove 2015) and seems to be locally on the verge of naturalization. In the Greek locality of Lagonisi, there are actually no cultivated plants of O. lindheimeri in the vicinity. However, the observed population of several individuals may have originated from the local seedbank, since there was a small nursery nearby, which was closed several years ago.

A2-33, p. 247). The host plant there was Cicerbita cf. petiolata (K. Koch) Gagnidze. Tzvelev (2015: 210) elevated O. flava subsp. cicerbitae to specific rank, without further explanation. We do not agree with this opinion, because there is no elementary new knowledge about the relationship between the two taxa, even after comparing material from Azerbaijan with the type collection of O. flava subsp. cicerbitae and Caucasian and European collections of O. flava subsp. flava. The matter needs further study.

DiagnosisOrobanche reticulata subsp. agigensis differs from O. reticulata Wallr. subsp. reticulata in the following characters: stigma always yellow, even in otherwise darker reddish-purple-coloured plants [O. reticulata subsp. reticulata: usually reddish purple, very rarely yellow in otherwise aberrant yellow-coloured plants, e.g. O. reticulata f. kirantha Beck]; filaments mostly inserted (1-) 1.5–2 mm above base of corolla tube, adaxial pair inserted only slightly higher than abaxial one [O. reticulata subsp. reticulata: insertion of abaxial filaments 2–2.5 mm and adaxial filaments 3–4 mm above base of corolla tube] ; filaments and corolla basally ± hairy, filaments in lower ⅓ or ½ distally scattered, below anthers often densely shortly glandular hairy [O. reticulata subsp. reticulata: filaments and corolla glabrous or very sparsely hairy at base and below anthers] ; apical mucro of anthers mostly yellowish-white-coloured to a length of 0.25–0.4 mm, mucro therefore seeming enlarged [O. reticulata subsp. reticulata: apical mucro only partly yellowish-white-coloured to a length of 0.15–0.25 mm, mucro therefore not seeming enlarged] ; ovary in distal part (especially ventrally) and style along whole length scattered to densely glandular hairy [O. reticulata subsp. reticulata: ovary usually glabrous, style glabrous or (especially below stigma) scattered shortly glandular hairy].

Distribution — Russia, NW Caucasus: known only from the broader Thač region on Trias sic limestone, but scattered there; a small distribution area without any known transitions to the nominate subspecies.

Ecology and hostsOrobanche reticulata subsp. agigensis grows in perennial mesic to moist tall forb vegetation at an altitude of 1700–2100 m. The main host is Carduus acanthoides L. s.l. and in one case very probably Cirsium pugnax Sommier & Levier. Orobanche reticulata subsp. agigensis is a late-blooming plant, flowering from the beginning of July to the beginning of September. The plant is mostly associated with O. grossheimii Novopokr.

Etymology — The subspecific epithet is derived from Mt Agige, a rock massif in the NW part of the Greater Caucasus, the type locality of the plant, and its surroundings.

RemarksOrobanche reticulata Wallr. is a rare species in Russia. During field work from 2001–2015, we found remarkable plants belonging to this species, but differing in several characters, which we here describe as O. reticulata subsp. agigensis. The new subspecies should be seen as an example of convergent evolution with O. alba subsp. xanthostigma Rätzel & Uhlich (Rätzel & Uhlich 2004; Piwowarczyk 2015b: 107; Uhlich & al. 2015). In both cases, taxa with obligate yellow stigma, additional quantitative differences and their own distribution areas have presumably evolved from species with red or purple stigmas. As in O. alba, forms of O. reticulata with yellow stigmas have been described in the literature, but they do not match entirely with the subspecies described here. In our opinion, all those cases merely represent anomalous colour forms within populations of otherwise typically developed and normally coloured plants. Concerning the infraspecific classification of O. reticulata, we follow the argumentation of Pusch (2009: 45) and propose two subspecies: subsp. reticulata and subsp. agigensis, with the former containing two varieties: var. reticulata and var. pallidiflora (Wimm. & Grab.) Beck (the latter variety including in synonymy O. procera W. D. J. Koch ≡ O. reticulata var. procera (W. D. J. Koch) Beck).

Rätzel). — Orobanche zajaciorum was previously known only from the type locality in the Lesser Caucasus, Georgia (Piwowarczyk 2015a), and from a second location in Armenia (Piwowarczyk 2016). The information in Piwowarczyk (2015: 215) about the ecology and the associated vegetation corresponds fairly well to the situation at the new location near Sachrai. The host plants, Scutellaria sosnowskyi Takht. reported by Piwowarczyk (2015: 215), and S. polyodon, both belong to the S. orientalis L. aggregate. The location near Sachrai is very rich in plant species, including different Orobanche taxa, three of which were described by Rätzel & Uhlich (2004). The type collection of O. zajaciorum is distinguished by a distinctive flower morphology with almost geniculate corolla (see Piwowarczyk 2015a: fig. 1, 2), a character that may only occasionally be observed in supposedly closely related species, such as O. caryophyllacea Sm. and O. teucrii Holandre. By contrast, this feature seems always to be present in O. zajaciorum; the material from Armenia (see Piwowarczyk 2016) and our plants from the Greater Caucasus also have such arcuate corollas. S.

It has been introduced to littoral areas of Algeria probably by the Spanish before the French colonization, as testified by engravings of old Algiers dating back to c. 1830, where adult trees of P. canariensis are documented together with Agave americana L. and Opuntia ficus-indica (L.) Mill. (Zeddam & Raus 2010). In Algeria, P. canariensis did not produce viable seeds before this last decade, and the recent occurrence of seedlings in locations where conditions appear rather unfavourable could highlight a new behaviour in population dynamics of the species, perhaps linked to changing climatic conditions. Deep and moist soils in gardens, cemeteries or green spaces seem to promote the germination of seeds and the relatively fast growth of seedlings to adult individuals producing fruits and constituting a danger for walls and graves. The fruits seem to be spread mainly by birds, the seeds perhaps also by ants, which could explain the occurrence of seedlings in wall cracks. Different sources classify the species as a weed, being invasive in areas of winter-rain climates in Australia, Chile (Institute of Pacific Islands Forestry 2013), California, U.S.A. (California Invasive Plant Council 2016+) and Tunisia (Brandes 2001: 11; Le Floc'h & al. 2010). Phoenix canariensis has also been documented as displacing native species and altering habitats” (Global Invasive Species Database 2005+). In Algeria, we consider the species as naturalized on the basis of the definitions by Pyšek & al. (2004).

Zeddam. — Native to NW Mexico, planted in Algiers decades ago as an ornamental tree along avenues, seaside promenades and in parks, the offspring nowadays easily establishing, particularly in the neighbourhood of adults. In Algeria, Washingtonia robusta seems to propagate only by seeds, as seedlings and saplings are generally located under or close to adult individuals except when seeds are taken and transported by birds. The species is naturalized in California and Arizona, U.S.A. (Flora of North America Editorial Committee 2000: 106) and is invasive in certain oceanic island groups (Hawaii and La Réunion; Institute of Pacific Islands Forestry 2013). On the basis of the actual locations of young individuals of W. robusta in Algeria, the species prefers habitats with sufficient available water, such as irrigated beds or moist cracks in sidewalks, where the seedlings survive regular weeding without any difficulty. Also Danin (2000: 313) noted that in Israel W. robusta is “established in disturbed ground with low competition and sufficiently wet ground” and “is expected to grow at a wide range of elevations in Israel as well”. Euro+Med (2006+) gives only continental Spain as an area of introduction of the species, without specified status. On the basis of the observation of non-planted advanced saplings and fertile adults, we consider W. robusta as naturalized in Algeria.

Polygonaceae

Polygonum excelsius (Karlsson) Uotila, comb. & stat. nov.Polygonum aviculare subsp. excelsius Karlsson in Nordic J. Bot. 19: 386. 1999.

Polygonum excelsius is probably an endemic taxon of the Scandinavian coast of the North Sea (Karlsson 2000: 267). It has a strictly erect habit with few branches, and all flowers in branchless axils of reduced leaves in spike-like inflorescences. In these characters it resembles P. bellardii All. and P. patulum M. Bieb., but the nuts are similar to those of P. aviculare L. A good illustration is available in Karlsson (2000: fig. 95). I here propose a new combination, needed for the treatment of the P. aviculare group at species level in Euro+Med PlantBase.

The Polygonum aviculare group is the most intricate complex in the genus, and it has been dealt with in various ways in Floras and checklists and in different parts of the Euro+Med area. Most treatments cover only a single country or group of countries, and a proper comparison between the taxa in, for instance, E Europe and in other parts of Europe has never been made. Original distribution patterns in the area have been obscured by extensive anthropogenic spreading of many taxa. Karlsson (2000), in his thorough treatment of the group in N Europe, accepted the members of the group at subspecific level, discussed their variability and synonymized several taxa that were traditionally treated as separate entities. This has been followed in several recent W European Floras and checklists, with the exception that P. aviculare and P. arenastrum are often still both accepted as species. The narrow species concept was used for the group in E European and Caucasian Floras and checklists, which include fairly little discussion of the relationships between the taxa. For Euro+Med PlantBase purposes, it is appropriate to accept species level for most of the taxa in the P. aviculare group, except for the most challenging P. neglectum Besser, which has often been included in P. aviculare s.str. but seldom in other taxa. In Euro+Med PlantBase it is treated as a subspecies of P. aviculare s.str.

In Dagestan, it grows in oak and hornbeam-oak forests on N-exposed hill slopes with an inclination of 40–60° and at altitudes between 540 m and 625 m. The population consists of 89 individuals, 41 of which were in the vegetative and 48 in the generative state. They occur in two adjacent plots within an area of 200 m2. The discovery of D. nervosa here is further evidence of the penetration of Hyrkan floristic elements through the foothills of the Caspian part of the Caucasus to the north, up to the city of Makhachkala.

Verbascum flavidum (Boiss.) Freyn & Bomm.

+ Rf(CS): Russia: Dagestan, near the city of Makhachkala, village of Talgi, Talginskoe gorge, E slope, 300 m, 13 May 2010, Murtazaliev (DAG). — New to Russia. There is verbal information that it grows also S of Makhachkala, in the foothills of the Kaytagskiy and Tabasaranskiy districts. There are also collections by E. V. Yarovenko in 2010 from the suburbs of the village of Arakul, Rutulskiy district, present in the herbarium of the Dagestan State University (LENUD). Verbascum flavidum also occurs in C, SW and S Transcaucasia (Budantsev 1998: 137). In S Dagestan it grows in grassy situations in the foothills.

Veronica amoena M. Bieb.

+ Rf(CS): Russia: Dagestan, Tabasaranskiy district, near the village of Maragha, 300 m, on dry clay slopes, E-exposed, 11 Apr 2010, Murtazaliev (DAG, LE). — New to Russia. Veronica amoena occurs in Azerbaijan, where the nearest locations to our finding are the foothills on the Absheron peninsula (Karjagin 1957: 488). At the time of discovery, the population in Dagestan consisted of a large number of plants, creating a dominant aspect in the spring vegetation there.

Veronica kaiseri Täckh.

+ Jo: Jordan: Upper Wadi Ghuweir, 30°36′N, 35°34′E, 4 Oct 2015, Gregor 14208 (FR) — New to Jordan. This species was so far known only from Sinai, Egypt (Laurent-Täckholm & Drar 1943; El Hadidi & al. 1999; Boulos 2002). The determination was confirmed by D. Albach by ITS sequence (GenBank accession number KX768117).

Tamaricaceae

Tamarix mascatensis Bunge

—Bl(M), Hs(S), Lu: Tamarix mascatensis was originally described from Oman (Bunge 1852: 60), and its distribution was later extended to nearby countries such as Yemen, Somalia, Ethiopia, Saudi Arabia, Iran and Pakistan (Schiman-Czeika 1964; Baum 1978; Qaiser 1981). The first record for the Iberian Peninsula (De Martis & al. 1985) was based on a specimen collected near Elvas, Portugal, which, according to the morphological description given by the authors, may well be a specimen of T. africana Poir. The range of T. mascatensis was later extended to other parts of the Iberian Peninsula and the Balearic Islands (Cirujano 1991, 1993), with a modified morphological description that placed it close to T. gallica L., which is very common in the Iberian Peninsula and Balearic Islands. As a result, T. mascatensis has been reported in different articles and regional Floras (Gil & al. 1996; Salazar & Quesada 2009). The main morphological feature given as differential by De Martis & al. (1985) and Cirujano (1991, 1993) was the insertion of the staminal filaments on the lobes of the nectariferous disc: reported to be paralophic in T. mascatensis and synlophic in T. africana and T. gallica (see Baum 1978). However, we have found that both synlophic and paralophic disc configurations occur as phenotypic variations in T. africana and T. gallica, as has already been stated for different Tamarix species (Zohary 1972; Villar & al. 2012). The other morphological features mentioned by De Martis & al. (1985) and Cirujano (1991, 1993) more closely match the typical features of T. africana and T. gallica and include a larger size of sepals and petals than in T. mascatensis. In addition, T. mascatensis has very distinctive leaves with an amplexicaul base, almost clasping along one-third of their length, as is evident from the type collection (holotype at W; isotypes at G, K and P). This character was never mentioned in the publications that reported T. mascatensis for the Iberian Peninsula, nor has it been found in any studied specimen identified as T. mascatensis in the Iberian Peninsula and the Balearic Islands. All the Iberian and Balearic T. mascatensis we have examined (see below) were, in fact, misidentified specimens of T. gallica. Therefore, the presence of T. mascatensis in the Iberian Peninsula and the Balearic Islands should be discarded.

Specimens examinedTamarix gallica: Spain: Almería, Desierto de Tabernas, Rambla de Tabernas, 310 m, 25 May 1995, Cabello (HUAL 16066); Huesca, Vedad de Fraga bords de l' Elie près de lanage, 200 m, 13 J un 1985, Charpin & al.
