Oberprieler, C.: On the taxonomic status and the phylogenetic relationships of some unispecific Mediterranean genera of Compositae-Anthemideae II. Daveaua, Leucocyclus and Nananthea. — Willde nowia 34: 341–350. — ISSN 0511-9618; © 2004 BGBM Berlin-Dahlem.

Sequences of the nrDNA internal transcribed spacer (ITS) region were analysed for 113 representative species of 59 genera of Compositae-Anthemideae to ascertain the systematic position of the three unispecific Mediterranean genera Daveaua, Leucocyclus and Nananthea. Daveaua anthemoides is found to be a member of a well supported clade of genera around the closely-knit Leucanthemum group, being a candidate (together with Heteromera and Otospermum) for a sister-group of this assemblage. For Leucocyclus formosus, which was considered to be closely related to Anacyclus due to its dorsiventrally flattened achenes, a position close to or even among representatives of Achillea is demonstrated, corroborating alleged relationships suggested by the flavonoid complements of these genera. Nananthea perpusilla, hitherto considered to be close to Anthemis due to its tetrasporic embryo sac development, is found to be more closely related to Tripleurospermum, which also shares the tetrasporic embryo sac and the indumentum of basifixed hairs.

Chromosome numbers of nine taxa from nine families of Calabrian angiosperms are reported: Aizoonhispanicum 2n = 32, Aristida adscensionis subsp. coerulescens 2n = 22, Galium palaeoitalicum 2n = 20, Lavandula multifida 2n = 22, Ludwigia palustris 2n = 16, Menyanthes trifoliata 2n = 54, Ranunculus fontanus 2n = 48, Salsola oppositifolia 2n = 72, Soldanella calabrella 2n = 40. The reports for Aizoon hispanicum, Aristida adscensionis subsp. coerulescens, Lavandula multifida and Salsola oppositifolia are the first from Italian populations. Mitotic metaphase microphotographs and drawings are presented for all taxa studied. Brief comments are given on karyotype morphology, cytogeography and relationships of selected taxa.

Danin, A.: Arundo (Gramineae) in the Mediterranean reconsidered. — Willdenowia 34: 361–369. — ISSN 0511-9618; © 2004 BGBM Berlin-Dahlem.

Finding the recently described Arundo hellenica in Italy initiated a study on the identity of taxa related to A. plinii, in the field, in the literature and in several herbaria. According to the somewhat preliminary results, besides A. donax with nodding leaves, three species with upright leaves are proposed for recognition in the Mediterranean. Their distribution and ecology are still incompletely known. A. plinii in its original sense is shown to be a 1–2 m high riparian plant, so far confirmed to occur in N Italy, S France and, perhaps, NE Spain. A. mediterranea is described as a new species for the illegitimately named A. mauritanica of Desfontaines, which has hitherto been erroneously recorded as “A. plinii” and is a caespitose reed with 1–5 m long obliquely erect culms that branch already in the first year; it grows on alluvial clayey soils or high river terraces along temporary water courses of N Africa, Israel, Cyprus, Greece, Crete, Lebanon and possibly other East Mediterranean countries. A. collina, including the recently described A. hellenica, is the lowest (0.5-2 [-3] m) and most drought resistant Arundo of the Mediterranean and forms monotypic grasslands on clay in badlands, on hill slopes up to 300 m, on sides of newly constructed roads, etc. and is currently known to occur in S Italy, mainland Greece and Crete.

Silene rothmaleri, described in 1956 by Pinto da Silva based on a single herbarium specimen collected in 1945, has been considered as extinct following unsuccessful searches at its locus classicus, the Ponta de Sagres. At nearby Cabo de São Vicente, a small population of at least 10 individuals exists, discovered in spring 2000 and more leisurely studied in 2004. The macro- and micromorphology of the revenant species are described and illustrated.

The goal of this research project was to carry out a thorough floristic survey of weeds in the traditional agriculture of the South Aegean island of Crete, Greece. Fieldwork was carried out by the authors from 2.4.-7.5.2003. Fifty cultivated localities were surveyed, at which 2455 plant records and 483 herbarium gatherings were made. Living material was collected for cytological investigation at UPA. A relational database of the results (localities, taxa observed, herbarium specimens, living material) was created and is placed online as an  electronic supplement (wi.34.34206_supplemental_content.pdf). The collections and observations were critically evaluated, and a catalogue of the taxa recorded at each locality is provided here. Distributional notes are provided on significant records and selected weed species that are indicators of (obligate to) traditional agriculture.

During the fieldwork for a monograph of the genus Eryngium, a new species was found. It is described as E. trisectum and illustrated. Only one locality, a serpentine habitat in the Central Taurus region of Turkey, is known thus far. The new species belongs to E. sect. Palmito and is closest related to the calcicolous E. palmito. For this section, a key to its now five species and a table of the most important features are presented.

Hand, R. (ed.): Supplementary notes to the flora of Cyprus IV. — Willdenowia 34: 427–456. — ISSN 0511-9618; © 2004 BGBM Berlin-Dahlem.

Focussing again on the chorology of vascular plants in Cyprus, the present notes summarize contributions by various authors. This instalment includes data on 164 taxa. Chenopodium striatiforme and C. strictum are new for the island. Taxonomic considerations result in the validation of the new combination Hedera pastuchovii subsp. cypria. Lactuca triquetra, a remarkable but much neglected endemic of Cyprus and Lebanon, is discussed as regards its taxonomy, distribution and ecology; its chromosome number (2n = 18) is given for the first time.

Eren, Ö., Gökçeoğlu, M. & Parolly, G.: The flora and vegetation of Bakırlı Dağı (Western Taurus Mts, Turkey), including annotations on critical taxa of the Taurus range. — Willdenowia 34: 463–503. — ISSN 0511-9618; © 2004 BGBM Berlin-Dahlem.

A monograph of Bakırlı Dağı, the northern summit range of the eastern Beydağları in the Western Taurus Mts, Turkey, is given. It includes an annotated floristic catalogue of 539 taxa and a survey of the high mountain vegetation. For eight taxa considerable distribution range extensions are reported. Seventeen taxa are new records for the Flora of Turkey grid C3. Distribution maps are presented for Helichrysum plicatum subsp. isauricum and Poa akmanii. Minuartia dianthifolia s.l. is revised; its subsp. cataonica and subsp. kurdica are sunk in synonymy of the ‘type’ subspecies. Two taxa, M. dianthifolia var. longipetala and M. xantalyensis are described as new to science. The diagnosis of the recently described Arab is lycia is amended for carpological characters. The flora in general is characterised as rich in endemics (28.2 %) of chiefly E Mediterranean (montane) origin and enhanced proportions of E Mediterranean and Irano-Anatolian chorotypes as mono- or virginals, reflecting the position of the study area at the coastal face of the Taurus, which is situated at the intersection of Mediterranean and Irano-Turania territories. In spite of increasing human impact by skiing and cattle-breeding, the conation of the sublime vegetation belts remained chiefly intact, whereas the boreal forests have been largely replaced by xerophytes secondary dwarf shrub communities. A total of 13 selvática plant communities (in psychosociologie terms) are distinguished in altitudes between 1800–2547 m, each briefly treated in site-ecological and embryological respects and classified uneconomically. Due to a taxonomically necessary correction, the combination Atinemos lycia-Laserpicio pedophilia subas's. arbeidsethos lycia is made. A vegetation profile of Bakırlı Dağı has been established, showing additionally the distribution of the different chorotypes within the communities along an altitudinal transect.

Of these, 97 species are new for Iran while some species not confirmed by recent collections are doubtful. Pertinent literature references and, for the newly reported species, locality and collection data are presented.

Jahn, R. & Kusber, W.-H.: Algae of the Ehrenberg collection — 1. Typification of 32 names of diatom taxa described by C. G. Ehrenberg. — Willdenowia 34: 577–595. — ISSN 0511-9618; © 2004 BGBM Berlin-Dahlem.

The present paper is the first in a series of papers typifying names of algae taxa, which Ehrenberg described as new, and illustrating the type specimens. In this paper, 32 diatom names from 18 genera in current use are typified, 58 infrageneric diatom names are evaluated. Diploneis atmosphaerica and Odontella rhomboides are validated as new names. Seven specimens are designated as the types for names of the genera Brebissonia, Gomphonema, Microtabella, Petrodictyon, Raphoneis, Rhopalodia, Zygoceros. Four names are attached to specimens that are either not available or not identifiable because of girdle band view or unrecognizable drawings. Three names are heterotypic synonyms of taxa described earlier. In addition, this paper presents an update on the organization of the Ehrenberg collection after it has been modernized through funds of the AlgaTerra project.
