Taxonomic position of Vermifrux abyssinica (A. RICH.) GILLETT and taxonomy of the tribe Loteae s.l. (Papilionaceae)
Authors: Tikhomirov V. N. , Sokoloff D. D. 
Published: August 2010

AbstractThe comparison between Vermifrux abyssinica (A.RICH.) GILLETT and other members of Loteae tribe demonstrates that this species is most similar to Dorycnopsis gerardii (L.) BOISS. The idea of the affinity of V. abyssinica with the species Lotus subgen. Syrmatium is not confirmed. V. abyssinica and D. gerardii differ from the genus Lotus as well as from the genus Anthyllis not less than Anthyllis differs from Lotus. On the other hand the distinctions between V. abyssinica and D. gerardii do not exceed the differences between species within the genus Lotus, so there are reasons to join the genera Vermifrux and Dorycnopsis. The new combination Dorycnopsis abyssinica (A.RICH.) V.TICHOM. & D.D.SOKOLOFF and the corrected description of the genus Dorycnopsis are given.

Life strategy systems of xerothermic grasslands – mechanisms of reproduction and colonization within Stipetum capillatae s.l. and Adonido – Brachypodietum pinnati
Authors: Hensen I. 
Published: August 2010

AbstractLife strategy systems of two xerothermic grassland types (Stipetum capillatae s.l., Adonido‐Brachypodietum pinnati) were studied. Five different life strategies are established. A detailed weighted analysis based on the Mean group quantity fraction shows that mainly the community‐specific soil water conditions effect a different significance of predominant colonization and reproduction mechanisms.Within both communities, Perennial stayers of hemicryptophytic life form are best adapted to this habitat. The most important life strategy within the summer‐dry Stipetum capillatae s.l. is that of Perennial stayers with long‐ and short‐range dispersal, with sexual reproduction (PTEs). Site colonization and maintenance takes place through generative, long‐ and short‐range dispersed diaspores, with clonal reproduction having a lower significance.By contrast, within Adonido‐Brachypodietum pinnati characterized by more moderate water conditions, Perennial stayers with long‐ and short‐range dispersal, with clonal reproduction (PTEcl) clearly dominate. Habitat is maintained by vegetative dispersal, and generative diaspores are produced infrequently.Within the grassland communities, there is a strong tendency towards short‐range dispersal. Yet, within Stipetum capillatae, polychorous species characterized by additional adaptations of epizoochorous long‐range dispersal, are biologically significant as well. From the results of the present analysis, different measures of habitat conservation can be derived.

Setchelliogaster rheophyllus comb. nova (Bolbitiaceae, Agaricales) – an Iberic and North African fungus species
Authors: Moreno G. , Kreisel H. , Galán R. 
Published: August 2010

AbstractSetchelliogaster rheophyllus, comb. nova, is described and illustrated. The species originally described from North Africa as Naucoria was confused in Spain with S. tenuipes. It is interesting for its systematic position between agaricoid and secotioid Basidiomycetes. It fruits in winter in humus of Eucalyptus globulus in allochthonous affore stations in Asturias and Vizcaya in northern Spain. The genus Setchelliogaster is interpreted as a secotioid member of the Bolbitiaceae.

Der Bauplan der Blüte und ihres Gefäßbündelsystems bei den Mesembryanthemen
Authors: Volgin S. A. 
Published: August 2010

AbstractMorphologische und gefäßbündelanatomische Untersuchungen der Blüte von Aptenia cordifolia (L. f.) SCHWANT. und Delosperma echinatum (LAM.) SCHWANT. haben gezeigt, daß ein Bauplan der Blüte bei den Mesembryanthemen als solcher beschrieben werden kann, für den ein mit der primären einfachen Blütenhülle homologer Kelch und ein Kreis den Kelchblättern gegenüberliegende Karpelle charakteristisch sind. Zwischen beiden Kreisen befindet sich eine Androeceumzone, die eine primär unbestimmte Zahl von staminodialen Kronblättern und Staubblättern in mehr oder weniger gleichmäßiger Anordnung besitzt. Die Verkürzung der Blütenontogenie kann zur Ausbildung alternisepaler Staminalgruppen und einzelner Stamina führen. Das Gynoeceum hat stark entwickelte Apikalsepten und mit ihnen alternierende falsche Scheidewände. Der untere Teil des Ventralspalts ist in einen zylindrischen Kanal umgewandelt. Das Gefäßbündelsystem ist meist aus den Spursträngen der appendikulüren Blütenteile aufgebaut. Die anatomischen Karpellnodien befinden sich auf dem Niveau des Ovarbodens. Es gibt keine anatomischen Hinweise auf eine axiale Natur der Ovarwand. Die Entstehung der Epigynie ist nicht mit der Verschiebung der Plazenten an die Ovarwände verbunden, die Verschiebung selbst ist nicht, durch die Veränderung der Proportionen des Blütenbodens verursacht. Ein solcher Bauplan schließt direkte verwandtschaftliche Beziehungen zwischen Aizoaceae und Cactaceae aus.
Root anatomy of palms IV. Arecoideae, part 1, general remarks and descriptions on the roots
Authors: Seubert Elke 
Published: August 2010

AbstractThis survey of palm roots, initiated with the Coryphoideae, and followed by Calamoideae, Ceroxyloideae, Nypoideae with the only genus Nypa and Phytelephantoideae is now completed with the studies on the roots of Arecoideae. Representatives of 101 genera of the 123 genera accepted by UHL & DRANSFIELD 1987 have been available. Within the subfamily, there is considerable variation in root characters. In general, roots do not differ or but slightly between species of a single genus, but do so conspicuously between the genera, subtribes, and tribes. They therefore contribute both to distinguish genera and to recognize natural units of genera, and indicate affinities between higher categories.Archontophoenicinae, Arecinae, and Iguanurinae have much in common and are obviousely related. According to root anatomy, Cyrtostachys is clearly a member of Archontophoenicinae. Dypsidinae are considered transitional between Linospadicinae, Ptychospermatinae, and Archontophoenicinae; whereas Oncospermatinae show affinites to Iguanurinae, but share also characters with Butiinae. Butiinae fall into two groups; one approaching Attaleinae and Elaidinae, the other one mainly characterised by reduction of root features. The character state, found within Bactridinae sets them apart from the rest of Cocoeae, but show some affinities to Caryoteae; this may be due to parallelism. Podococceae are considered related with Reinhardtia (Malortieinae) and Iriarteae, the latter with several characters in common with Caryoteae. As the roots of Oraninae are reduced, and most features are wanting, it is doubtful if they are closer to Areceae or Podococceae. In any case, they have more in common with the Podococceae and Malortieinae than with the rest of Areceae. Euterpeinae and Roystoneae are similar in root anatomy, and thus considered closely related. Geonomeae have little in common with the rest of the subfamily, but approach Phytelephantoideae.
Alien plants in Czech village flora: An analysis of species numbers
Authors: Pyšek P. 
Published: August 2010

AbstractFlora of 42 villages located at the territory of the Czech Republic between 12–16 °E and 49–51 °N was analysed to (1) quantify the proportion of archaeophytes (i.e. aliens introduced before 1500), neophytes (aliens introduced after that date) and native species, and (2) assess the factors affecting the representation of these particular groups. Alien species constitute on average about one third of the species present in the flora of a Czech village, archaeophytes contributing 17.8% (32.3 species), neophytes 14.4% (26.8 species). Number and proportion of archaeophytes increased with village size and decreased with its altitude, native species were correlated with neither factor. Village size, expressed as the number of houses, and the distance from a middle‐sized town were the significant predictors explaining nearly 50% of variation in number of neophytes. There was also an effect of geographical region in which a village was located on the representation of neophytes. Neither the richness nor the proportion of neophytes in village floras were correlated with the distance from a small town or that from railway, nearest river and main road.
Wadi vegetation of the North‐Eastern desert of Egypt
Authors: Fossati J. , Pautou G. , Peltier J. P. 
Published: August 2010

AbstractThe spatial structure of the wadi vegetation of the North‐eastern Desert of Egypt was analyzed on a regional scale (30° 10′ N to 26° 10′N and 30°50′ E to 32°30′ E). The site covers 400 km from north to south and 150 km from west to east.Phytosociological relevés selected from published papers were added to authors' relevés from the Wadi Sannur. The analysis of the distribution of perennial species was based on 237 relevés. Four communities identified were described in relation to two climatic gradients, the first of which, the north/south gradient, is characterized by decreasing annual precipitations and an increasing mean annual temperature. The second, the north‐west/south‐east, presents an increase in the annual potential of evapotranspiration. A third gradient, a biogeographical one this time, exerts an important role in the floristic composition. The whole of the eastern Desert is dominated by the Saharo‐Arabian species but as one moves northward, the proportion of the Mediterranean taxa increases. Some Sudano‐Angolan taxa also appear in the southern part.
Vegetation pattern along an edaphic and climatic gradient in the Southern Eastern Desert of Egypt
Authors: Sheded M. G. 
Published: August 2010

AbstractVegetation analysis of the Aswan–Allaqi road in the Southern Eastern Desert of Egypt indicates the dominance of Morettia philaeana, Aerva javanica, Fagonia indica, Salsola imbricata, Pulicarica crispa, Crotalaria aegyptiaca, Lotononis platycarpa, Citrullus colocynthis, Pulicaria incisa, Astragalus vogelii and Zygophyllum simplex. Four vegetation clusters are recognized after the application of the Two‐Way Indicator Species Analysis (TWIN‐SPAN). These clusters are named after the dominant species as follows: Fagonia indica – Aerva javanica, Salsola imbricata – Zilla spinosa, Salsola imbricata – Morettia philaeana and Salsola imbricata – Aerva javanica. Among the estimated soil variables in the present study, silt, clay, pH, EC, HCO3, CI−, and Ca2+ are important in characterizing the vegetation clusters.

Bislang nicht typisierte Namen von Rubus‐Arten in Mitteleuropa
Authors: Weber H. E. 
Published: August 2010

AbstractDie bislang nicht typisierten Namen der in Mitteleuropa vorkommenden Brombeerarten sind, soweit möglich, typisiert: Insgesamt sind 25 Lectotypen ausgewählt, außerdem vier Neotypen, die am locus typicus gesammelt oder vom Autor nach Publikation seines betreffenden Namens entsprechend beschriftet wurden. Zusätzlich sind einige Synonyme und infraspezifische Taxa typisiert. Bei Rubus cimbricus FOCKE konnte bislang nur ein Iso‐Syntypus gefunden werden, und von R. loehrii WIRTGEN sind nur Syntypen bekannt, die wenig instruktives und daher zur Lectotypisierung nicht verwendbares Material enthalten. Ein Holotypus R. gremlii FOCKE wurde noch nicht wiederentdeckt. Rubus godronii LECOQ & LAMOTTE und R. mougeotii BILLOT wurden nicht typisiert, doch ist die Anwendung auch dieser Namen durch authentisches Material gesichert.
The beech (Fagus L.) in western Eurasia–an actualistic approach
Authors: Denk Th. 
Published: August 2010

AbstractFloristic investigations in the western Eurasian area of Fagus L. were carried out to provide a basis for comparison with European Late Tertiary plant assemblages containing Fagus. Beech turned out to be part of polydominant forests in marginal regions of its range. It is of interest that Fagus occurs together with a number of evergreen species not only in the well known Tertiary relict areas of Northern Turkey and western Georgia, but also in Southwestern Europe. Coastal stands in the Georgian Colchic area with high atmospheric humidity turned but to be most significant for the actualistic approach. Small‐scale mosaic patterns of distinct vegetation units could be observed. They are caused by differences in soil drainage and fluctuating ground water levels. Such conditions are supposed to be very similar to Neogene vegetation types reflected in the fossil record.Spontaneous spreading of exotic plants in Georgian mixed broadleaved evergreen forests but also in southern Switzerland demonstrates the abundance of free niches in contemporaneous broadleaved forests. Climates with evenly distributed high amounts of annual precipitation and no severe winter and late frosts seem to favour such phenomena.Monodominant beech forests are derived vegetation types of the postglacial period and occur throughout the whole area of Fagus in western Eurasia.

Use of chloroplast DNA polymorphisms for the phylogenetic study of Allium subgenus Amerallium and subgenus Bromatorrhiza (Alliaceae) II
Authors: Samoylov A. , Friesen N. , Pollner S. , Hanelt P. 
Published: August 2010

AbstractThe utility of the chloroplast DNA (cpDNA) restriction mapping of 18 Allium species of the subgenera Amerallium, Melanocrommyum, Allium and Bromatorrhiza have been cladistically analysed, according to the recently proposed paraphyletic origin of the subgenera Bromatorrhiza and Amerallium. The size of the restriction fragment and the precise fragment order of A. zebdanense cpDNA were determined for 10 enzymes. The parsimony analysis confirms strongly the subdivision of the genus Allium in two main groups with different basic chromosome numbers (x = 7 and x = 8), which had been earlier proposed on the basis of morphological, karyological, anatomical and other molecular markers. Subgenus Amerallium (x = 7) itself is distinctly differentiated into two main subgroups, representing the Eurasian and the American taxa. The subgeneric status of Bromatorrhiza has to be cancelled, its members must be subordinated as sections to subgenus Amerallium (sect. Bromatorrhiza) and to one of the Eurasian subgenera with x = 8 (probably to the subgenus Allium or Rhizirideum).

AbstractDie aktuelle und historische Verbreitung vonChamaesyce‐Arten werden in Verbreitungskarten (UTM‐Gitter) dargestellt (Ch. canescens, Ch. glyptosperma, Ch. humifusa, Ch. maculata, Ch. nutans, Ch. prostrata, Ch. serpens). Verbreitung, Häufigkeit und Höhenverbreitung werden in Beziehung gesetzt zu Boden und Klima. Dabei ergibt sich, daß die potentiellen Arealgrenzen noch nicht erreicht sind; die Arealausweitung ist in erster Linie im Zusammenhang mit der Arealsättigung zu sehen, nicht als Folge einer Klimaänderung. Mit weiteren Arealveränderungen und zusätzlichenChamaesyce‐Arten ist in Zukunft zu rechnen.

Evolutionary and taxonomic studies of Ipomoea L. sect. Involucratae BAK. & RANDLE (Convolvulaceae) in Nigeria
Authors: Ogunwenmo K. O. 
Published: August 2010

AbstractTaxonomic circumscription of the Nigerian material of Ipomoea pileata is suggested owing to its uniqueness from the Asian and other African specimens. Cotyledon size, presence or absence of inner, sepal‐like bracts, sepal's shape, colour and size of corolla, stigma colour and number of flower per involucre‐bract among others are diagnosticable. Evolutionary mechanisms leading to speciation in Ipomoea sect. Involucrutae include shortening of life cycle with development of long seed dormancy period, variation of flower opening and closing periods, reduction in size and number or loss of floral part(s), inbreeding and geographical isolation. Chromosome counts revealed 2n = 30 with different lengths (P < 0.01). A new taxon. Ipomoea involucrata P. BEAUV.var. involucrata f. bicolor OGONWENMO f. nova is described.
