Kadereit, G., Hohmann, S. & Kadereit, J. W.: A synopsis of Chenopodiaceae subfam. Betoideae and notes on the taxonomy of Beta. – Willdenowia 36 (Special Issue): 9-19. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: A synopsis of the phylogeny and systematics of subfamily Betoideae of the Chenopodiaceae is provided and a modified subfamilial classification proposed. Betoideae contain five or six genera, i.e. Beta, Patellifolia, Aphanisma, Oreobliton and Hablitzia. The inclusion of Acroglochin in Betoideae is not clearly resolved by molecular evidence. The five genera (excl. Acroglochin) fall into two clades. These are Beteae with Beta only, and Hablitzieae with the remaining four genera. Of these four genera, Patellifolia formerly has been regarded as a section of Beta (B. sect. Procumbentes). The closer relationship of Patellifolia to Hablitzieae rather than to Beta is supported not only by molecular but also by flower morphological characters. Molecular evidence, in part newly generated, suggests that Beta can be divided into two well-supported groups. These are B. sect. Corollinae and B. sect. Beta. The often recognized unispecific B. sect. Nanae should be included in B. sect. Corollinae. In B. sect. Beta, probably only two species, B. macrocarpa and B. vulgaris, should be recognized.; Key words: angiosperms, beets, Patellifolia, phylogenetic systematics, ITS, morphology.

Freitag, H. & Lomonosova, M.: Typification and identity of Suaeda crassifolia, S. prostrata and S. salsa, three often confused species of Suaeda sect. Brezia (Chenopodiaceae, Suaedoideae). – Willdenowia 36 (Special Issue): 21-36. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: The nomenclatural history of the three common and often confused species Suaeda crassifolia, S. salsa and S. prostrata, distributed from Europe to S Siberia and Middle Asia, is outlined, their identity is critically discussed and the three names are typified. The differential characters of the three species are presented in a table.; Key words: Peter Simon Pallas, halophytes, Eurasia, taxonomy, lectotypification.

Bigazzi, M., Nardi, E. & Selvi, F.: Palynological contribution to the systematics of Rindera and the allied genera Paracaryum and Solenanthus (Boraginaceae-Cynoglosseae). – Willdenowia 36 (Special Issue): 37-46. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: The pollen of thirteen species of Rindera, ten of Solenanthus and eight of Paracaryum was examined by light and scanning electron microscopy. Two main pollen types are recognised, one typical of most Rindera species (Rindera tetraspis type) and one occurring in all but one species examined of Paracaryum and Solenanthus (Cynoglossum officinale type). Deviations from the Rindera tetraspis type in Rindera were observed in R. tianschanica, which is characterised by the Cynoglossum officinale pollen type, and R. gymnandra, which shows the Pardoglossum atlanticum type as already published. Within Paracaryum and Solenanthus the only remarkable deviation from the Cynoglossum officinale type was found in Solenanthus hupehensis from China. In the constricted shape and the lack of an ectocingulus, the pollen of this species approaches the Myosotis arvensis type, which is rarely found in the tribe Cynoglosseae. Combined with other morphological peculiarities, pollen characters support the placement of S. hupehensis in a subgenus of its own, S. subg. Silvestria, named after the discoverer of this species.; Key words: angiosperms, micromorphology, pollen, scanning electron microscopy, Solenanthus subg. Silvestria, taxonomy.

Vogt, R. & Oberprieler, C.: The genus Plagius (Compositae, Anthemideae). – Willdenowia 36 (Special Issue): 47-68. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: A comprehensive treatment of the small western Mediterranean genus Plagius, including morphological, anatomical and cytological details and distribution maps, is presented and the results of a phylogenetic analysis based on nrDNA internal transcribed spacer (ITS) sequence variation discussed. The three species of Plagius are found to form a monophyletic group with 88 % bootstrap support within the Leucanthemum group of genera, which is characterised by a specialised achene anatomy. The chromosome numbers of P. maghrebinus (2n = 18) and P. grandis (2n = 36) are reported for the first time. The basionym of P. grandis is lectotypified.; Key words: Mediterranean, taxonomy, chromosome number, lectotypification.

Ehrendorfer, F. & Guo, Y.-P.: Multidisciplinary studies on Achillea sensu lato (Compositae-Anthemideae): new data on systematics and phylogeography. – Willdenowia 36 (Special Issue): 69-87. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: On the basis of extended DNA sequences (nrITS, cptrnL-F) and other new evidence present know– ledge on the differentiation of the northern hemisphere Compositae-Anthemideae genus Achillea in time and space is surveyed. Evidence is presented for a wide circumscription of the genus with 110-140 species. This includes the former unispecific genera Otanthus and Leucocyclus, which have originated from ancestors of the basalmost clade of Achillea, the xerophytic A. sect. Babounya s.l. (incl. sect. Arthrolepis and Santolinoideae). Maps show the predominantly SW Asian distribution of the section and its derivative, A. (sect. Otanthus) maritima, a psammophyte of the Mediterranean and Atlantic coasts. Through taxa from the Caucasus differentiation has proceeded from A. sect. Babounya-like ancestors to the Eurasian and more meso– and hygrophytic 2x members of A. sect. Ptarmica s.s. They are linked with 2x A. asiatica (A. millefolium agg.) by the hybrid 4x A. alpina agg., which has expanded across northern North America. A. sect. Anthemoideae s.l. consists of several distinct clades distributed in the mountain systems of NW Anatolia, the Balkans, Carpathians, Alps, Apennines and E Pyrenees. This section was formerly combined with A. sect. Ptarmica but is closer to the following section and may be polyphyletic. A. sect. Achillea includes closely related taxa with white and yellow(ish) ligulate flowers (the latter formerly separated as A. sect. Filipendulinae). Members of the section have differentiated from a centre of diversity in dry habitats of SE Europe, partly into uniform 2x species, partly into polymorphic and polyploid species groups. "Crown group" of the genus and section is A. millefolium agg., a strongly diversified polyploid complex. Its basal 2x species exhibit a vicarious and sometimes relic differentiation pattern. They are connected in a complex way to several parallel and reticulate lines of 4x, 6x and 8x taxa, which are partly very expansive. From 4x A. asiatica-like ancestors in E Siberia the 4x and 6x A. borealis has successfully radiated into many ecological niches in North America and 6x A. millefolium s.s. has become a cosmopolitan weed.; Key words: nr + cpDNA, polyploidy, ecological radiation, Asteraceae, Leucocyclus, Otanthus.

Dathe, S. & Dietrich, H.: Comparative molecular and morphological studies in selected Maxillariinae orchids. – Willdenowia 36 (Special Issue): 89-102. – ISSN 0511-9618; ©2006 BGBM Berlin-Dahlem.: The phylogenetic relationships within Orchidaceae subtribe Maxillariinae s.str.were investigated by Maximum Parsimony and Bayesian analyses of nuclear ribosomal ITS1 and ITS2 DNA sequences in 27 species. While the monophyly of Maxillariinae is supported, Maxillaria in its current, narrower circumscription is clearly paraphyletic, since all presently accepted genera examined (Chrysocycnis, Cryptocentrum, Mormolyca, Trigonidium) and the former segregates Camaridium, Heterotaxis, Marsupiaria, Neourbania, Ornithidium and Pseudomaxillaria are nested within it. Camaridium, Heterotaxis and Ornithidium are, moreover, polyphyletic. The resulting molecular trees show six more or less well supported clades but are not very well resolved in their basal parts. To study character evolution, the molecular data were compared with pollinarium morphology, using scanning electron microscopy in 22 taxa, and further morphological data. The comparison indicates that most features have evolved several times independently. In growth habit a trend from caespitose to rhizomatous is found. Palynologically three morphological lines are indicated: (1) from four greater pollinia in two pairs to four smaller, equal, separate pollinia; (2) from spherical to clavate pollinia; (3) from pollinia with rugulate (sometimes gemmate, granulate, fossulate, microfoveolate) to psilate surface. A more extensive taxon sampling is needed to decide if and how Maxillaria s.l. has to be divided in smaller monophyletic genera.; Key words: phylogeny, systematics, ITS, pollinarium, Maxillaria, Orchidaceae.

Marhold, K., Duchácek, M. & Hroudová, Z.: Typification of three names in the Bolboschoenus maritimus group (Cyperaceae). – Willdenowia 36 (Special Issue): 103-113. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: In the absence of original herbarium specimens, illustrations are selected as lectotype for two names in the Bolboschoenus maritimus group, Scirpus compactus and Scirpus maritimus var. cymosus. To the ambiguous lectotype for Scirpus compactus an epitype is added, which fixes the name as a synonym of Bolboschoenus maritimus. The lectotype for Scirpus maritimus var. cymosus belongs to Bolboschoenus laticarpus. The holotype of Scirpus macrostachys is ambiguous and an epitype is chosen which supports its synonymy with Bolboschoenus glaucus. The taxonomic significance of the macrostachyate morphotype is discussed.; Key words: taxonomy, lectotype, epitype, Scirpus, macrostachyate morphotype.

Sukopp, H.: Botanische Gärten und die Berliner Flora [Botanic gardens and the flora of Berlin]. – Willdenowia 36 (Special Issue): 115-125. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: In the botanical gardens and arboreta of Berlin many vascular plant taxa have been cultivated since 1573. The influence on the composition of the flora of Berlin by the dispersal of plants escaping from its botanical gardens is assessed. Some spectacular examples are known: Galinsoga parviflora, Matricaria discoidea, Parietaria pensylvanica, but no systematic survey exists. Arboreta are of importance for some trees and shrubs because of a deliberate release in great quantities.; Key words: botanical garden, arboretum, neophytes, plants introduction, Germany, Berlin.

M. & Domina, G.: Ptilostemon greuteri (Compositae), a new species from Sicily. – Willdenowia 36 (Special Issue): 169-175. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: The rare Ptilostemon greuteri from NE Sicily is described as a species new to science and illustrated. It belongs to P. sect. Ptilostemon due to its non-spiny leaves and the corymbose synflorescence. From the two other species of this section, P. chamaepeuce and P. gnaphaloides, it differs strikingly by the larger size of the whole plant, the flat, lanceolate leaves and the absence of peripheral male flowers. The species, of which about 250 individuals are known, is restricted to a single locality and must be classified as endangered.; Key words: Asteraceae, Cardueae, taxonomy, endemism, Mediterranean region.

Ancev, M. & Goranova, V.: Trichome morphology of eleven genera of the tribe Alysseae (Brassicaceae) occurring in Bulgaria. – Willdenowia 36 (Special Issue): 193-204. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: The leaf and silicule trichomes of 18 species of Alysseae were studied by scanning electron and light microscopy. Four trichome types are distinguished: (1) simple, (2) stalked 2– to 5-armed, (3) stellate and (4) dendritic trichomes. (1) Simple trichomes cover the leaves of Lunaria rediviva and, mixed with stalked 2– to 3-armed ones, compose the leaf indumentum of Camelina sativa. The simple trichomes on the silicules of Clypeola jonthlaspi subsp. microcarpa are columnar with transverse furrows. (2) Stalked 2-5-armed trichomes are present on the leaves of Draba korabensis, D. muralis, D. siliquosa and Erophila verna subsp. spathulata. Peculiar stalked trichomes with swollen globular base occur on the lower leaf surface of D. muralis. (3) Stellate trichomes cover the leaves of Alyssoides utriculata subsp. bulgarica, Aurinia saxatilis subsp. orientalis, A. uechtritziana and Clypeola jonthlaspi and the leaves and silicules of Alyssum cuneifolium s. str., A. orbelicum, A. pirinicum and Fibigia clypeata. (4) Dendritic trichomes co-occur with stellate ones on the silicules (but rarely on the leaves) of Berteroa species and Fibigia clypeata. The trichomes may be smooth (some stellate trichomes), minutely warty (simple and dendritic trichomes) or tuberculate (most of the stellate trichomes). The trichomes of the morphologically related species Alyssum pirinicum, a new combination validated here, and A. cuneifolium provide additional reliable features to distinguish them.; Key words: angiosperms, Cruciferae, indumentum, micromorphology, scanning electron microscopy.

Raus, Th.: Found and lost – Staphyleaceae in Greece. – Willdenowia 36 (Special Issue): 311-315. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: The angiosperm family Staphyleaceae, represented in the Flora Hellenica area by just one genus and species, Staphylea pinnata, was not known to occur in Greece until recently. Alas, its single known Greek population is definitely destroyed. As a consequence, the status of extinction in Greece has to be attributed to the family, genus and species as long as a reconfirming collection is wanting.; Key words: floristics, Red List, endangered plants, extinct plants.

Søndergaard, P. & Egli, B. R.: Zelkova abelicea (Ulmaceae) in Crete: floristics, ecology, propagation and threats. – Willdenowia 36 (Special Issue): 317-322. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: Field work during twenty years in the mountains of Crete has disclosed that the endemic deciduous tree Zelkova abelicea is more abundant than hitherto reported. The number of mature and old trees is estimated to reach several hundreds, while Z. abelicea scrub browsed by sheep and goats comprises thousands of individuals. The species is extremely resistant to browsing and regenerates by suckers after forest fires. Z. abelicea suckers freely and suckering is an efficient way of propagation in the wild, while natural regeneration by seed was very rarely seen. Root cuttings from all four mountain ranges of Crete were taken to Denmark and 50 % successfully rooted. Best results were obtained with root cuttings taken in late autumn. Branch cuttings of newly matured shoots from young plants were rooted with good results when taken after midsummer. Z. abelicea has been grown outdoors in milder areas of Scandinavia during five years with only insignificant frost damage after cold winters. Currently it is not threatened with extinction but remains vulnerable.; Key words: Greece, Kriti, flora, conservation, cultivation.

Oberprieler, C. & Vogt, R.: The taxonomic position of Matricaria macrotis (Compositae-Anthemideae). – Willdenowia 36 (Special Issue): 329-338. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: Sequences of the nrDNA internal transcribed spacer (ITS) region were analysed for 116 representative species of 59 genera of Compositae-Anthemideae to ascertain the taxonomic position of Matricaria macrotis, a rare and enigmatic species from the E Aegean. The phylogenetic reconstruction indicates that M. macrotis is nested within the genus Anthemis s.str. next to members of A. sect. Maruta. This result is supported by morphological features. The previous inclusion of this species in the genus Matricaria was mainly based on the absence of receptacular scales (pales), whereas several characters of indumentum, achene morphology and achene anatomy support its transfer to Anthemis. The new combination Anthemis macrotis is validated and a lectotype for the basionym designated.; Key words: Asteraceae, Anthemis, systematics, ITS, Aegean, Greece, Turkey.

Data for 1109 indigenous phanerogam species were used for the production of a similarity matrix and taxon richness maps for each island, showing the representation of its flora in Europe. Jaccard's similarity index values of each island and related mainland areas show a strong floristic similarity between the large W Mediterranean islands Corsica, Sardinia and Sicily, and parts of their adjacent mainland, which reflects a common geological history. The maps show that the Balearic Islands have many species in common with Malta, which depends on the prevailing pan-Mediterranean element. Many Sicilian taxa show up in the Balkans, while many species of (the mountains of) Corsica, Sicily and to a lesser extent of Sardinia appear in Central Europe. Such an element is absent in Crete, Malta and the Balearic Islands. Crete deviates widely from the other investigated areas as it has many species in common with the Cyclades and mainland Greece, but less so with the Balkans.; Key words: phanerogams, phytogeography, Balearic Islands, Corsica, Crete, Malta, Sardinia, Sicily.

Baumann, H.: Von Lilienblüten aus minoischer Sicht [Lily flowers in Minoan art]. – Willdenowia 36 (Special Issue): 389-395. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem.: The numerous Minoan wall paintings known from excavations in Crete and on Thera, Greece, display a remarkable freshness of approach in their detailed naturalistic portraying of plants. Among the most spectacular is the fresco displaying lily-like flowers in the excavated Room of the Ladies at Akrotiri on Thera (Santorini island), which can be identified as sea daffodils (Pancratium maritimum, Amaryllidaceae). However, the large, crescent-shaped anthers of the flower are represented as standing on the teeth of the corona instead of on slender filaments between the teeth. Seemingly the Aegean artist strived by this arrangement to achieve a better harmony of design, but he thus came to show seven anthers instead of six. The magic attached in the number seven may have played a part. In contrast, in a motive of the sea daffodil on a bronze Mycenaean sword, the number of anthers is six.; Key words: archaeology, Minoan art, botany, Pancratium, Santorini.

This contribution summarizes and expands the knowledge of distribution, ecology and phytosociology for P. leptophyllus. The species is endemic to the Central and Eastern Rif Mts, with an outpost in the Tazzeka Mts of the N Middle Atlas. It is strictly acidophilous and colonizes fissures of schist bedrock and moderately moving micaschists, mostly in the meso-Mediterranean bioclimate at 1000-1300 m altitude. P. leptophyllus occurs in three different communities: (1) P. leptophyllus-Antirrhinum tortuosum community in the semi-arid, winter-cold Eastern Rif Mts around Tizi Ouzli; (2) Echium canum-Rumex thyrsoides community in the semi-arid, winter-mild lowlands of the Oued Rhis; (3) Convolvulus dryadum-Silene martyi community in the subhumid, meso-Mediterranean bioclimate. In all three communities caespitose hemicryptophytes are the predominant life form and Rif endemics such as P. leptophyllus, Convolvulus dryadum, Silene martyi and S. ibosii are a prominent chorotype. The pioneer character of other Ptilostemon species and the role of the rock environment as an evolutionary trap are discussed.; Key words: rock communities, Asplenietea rupestris, Morocco, evolution, phytochorology, endemism.
