Authors: El‐Karemy Z. A. R. , Hosni H. A. 
Published: August 2010

AbstractA systematic revision of the Egyptian species of the family Primulaceae was carried out. It reveals the presence of the following taxa: Primula boveana L., Asterolinon linum‐stellatum (L.) DUBY, Anagalis arvensis L. var. arvensis, A. arvensis L. var. caerulea (L.) GOUAN, A. arvensis L. var. latifolia (L.) LANGE, Samolus valerandi L. and Coris monspeliensis L. subsp. strossiae GAUBA. Of these A. arvensis L. var. caerulea (L.) GOUAN is a new record to the flora of Egypt. A key, synonyms and notes on distribution are provided.SEM features of the seed coat and leaf epidermis viz. of the cell patterns, anticlinal cell boundaries and the periclinal cell wall were also examined and proved their taxonomic significances.
The ruderal vegetation of the Mediterranean desert of Egypt With 3 Figures and 4 Tables
Authors: El‐Kady H. F. 
Published: August 2010

AbstractFive vegetation groups have been recognized along the roadsides of Alexandria‐Sallum highway in the Mediterranean desert of Egypt: group I codominated by Halogeton alopecuroides (Del.) MOQ. and Launaea resedifolia KUNTZE, group II codominated by Echinops spinosissimus TURRA and Polygonum equisetiforme SIBTH. et SM., group III codominated by Hammada scoparia (POMEL) ILJIN and Thymelaea hirsuta (L.) ENDL., group IV codominated by Zygophyllum album L. f. and Plantago albicans L. and group IV codominated by Zygophyllum album L. f. and Helianthemum lippii L. The species diversity of these communities and the ecological amplitude of their leading species along some edaphic gradients were evaluated and discussed.
Structure and distribution of plant trichomes in relation to taxonomy: Indian Physalis L. With 15 Figures and 2 Tables
Authors: Sudhakaran S. , Ganapathi A. 
Published: August 2010

AbstractThe structure and organographic distribution of trichomes in six Physalis L. (Solanaceae) taxa available in the Indian natural populations have been studied. In all, seven trichome types are recognised. Structurally they are distinguishable into two hair classes one comprising sequence from unbranched hairs to branched, dendritic hairs with or without glandular tips. While the other class consists of short hairs each tipped with a unicellular or multicellular head. Of the seven types recognised the unbranched eglandular trichomes present in all the six taxa. Branched trichomes are absent in P. minima and P. angulata. Whereas branched hairs are available with all the other taxa studied. P. peruviana can easily be identified by its dentritic trichomes present in its corolla thorat. The white flowered form is the only form having branched glandular hairs. The glabrescent form is having glabrescent texture and the storied gland with unicellular head. There is no storied glandular trichomes in the case of P. pubescens which is having long silvery hairs around the stem. The distribution of trichomes in general is taxonomically significant. Accordingly a key based on the trichome types for identification of the species is presented.
Foliar stomatal distribution in relation to taxonomy: Amaranthaceae With 6 Figures and one Table
Authors: Padmini S. , Rao S. Raja Shanmukha 
Published: August 2010

AbstractFoliar stomatal distribution and their taxonomic significance in 45 taxa belonging to 19 genera of the Amaranthaceae have been investigated. Of these, 41 taxa show amphistomatic leaves and the rest are hypostomatic. Based on the dispersion and orientation of stomata, six basic and combination patterns each have been recognised. Many taxa reveal diagnostic stomatal distributional patterns and their taxonomic utility has been discussed. Further, an attempt is made to correlate the stomatal distribution with the plant habit.

Epidermal studies of some species of family Solanaceae used in traditional medicine in West Africa
Authors: Nyawuame H. G. K. , Gill L. S. 
Published: August 2010

AbstractLeaf epidermal structure and developmental pattern of the stomatal complex of 30 species of the family Solanaceae are described. Epidermal cells of almost all the species showed wall sinuousity. However, in Brunfelsia uniflora and some species of the genus Solanum viz. S. aethiopicum, S. dasyphyllum, S. macrocarpon and S. verbascifolium the cells were straight‐walled. Several types of epidermal hairs were observed on both the upper and lower epidermis. They include bicellular eglandular, multicellular stellate and club‐shaped hairs. The leaves of most species were amphistomatic; however, a few species with hypostomatic leaves were also encountered. Mature stomata were either anomocytic or anisocytic with hemimesogeneous developmental pattern. In Schwenkia americana, however, mature stomata were diacytic with eumesogenous developmental pathway. Interspecific variation observed in the distribution, size and frequency of stomata may prove useful in the authentication of the foliar materials of these plants when used as crude drugs.

Should Cardaria draba (L.) DESV. be classified within the genus Lepidium L. (Brassicaceae)? Evidence from subunit polypeptide composition of RUBISCO
Authors: Mummenhoff K. 
Published: August 2010

AbstractThe polypeptide composition of the large and small subunits of ribulose‐1,5‐bisphosphate carboxylase/oxy‐genase (RUBISCO) from Cardaria draba (L.) DESV. (Brassicaceae) and from representatives of the related genus Lepidium L. have been studied by isoelectric focusing (IEF) analysis. In the literature Cardaria DESV. is either treated as a separate genus or as a section within the genus Lepidium Cardaria draba (L.) DESV. and three Lepidium taxa of section Lepia (DESV.) DC. are characterized by identical polypeptide patterns otherwise not found in Lepidium. RUBISCO data would preliminarily suggest that C. draba has its closest relatives within Lepidium section Lepia and therefore could possibly be placed best within this section.

Published: August 2010

AbstractThe vascular flora of subalpine and upper montane grasslands of Mts Menikion, Pangeon, Falakron, Orvilos in E Macedonia was investigated. A list of 547 taxa, which are classified to 59 families, 225 genera, 401 species and 146 subspecies, is presented. The majority of the taxa are hemicryptophytes (66.4%). The chamarphytes are also highly represented (16%), though to a much lesser extent. On the basis of duration of life, perennial herbs predominate. As far as it concerns the chorological distribution of the taxa, a remarkable dominance of the “northern”‐in a wide sense‐with an abundance of Balkan endemics is observed.

Wuchsverhalten und Infloreszenzstruktur in der Gattung Nebelia (Bruniaceae)
Authors: Classen‐Bockhoff R. 
Published: August 2010

AbstractDie Verzweigungs‐ und Blühverhältnisse von fünf Nebelia‐Arten werden detailliert dargestellt, Alle Arten wachsen als Hartlaubsträucher und sind Elemente des südafrikanischen Fynbos. Sie sind sympodial organisiert; bei einigen Arten treten jedoch mehrere monopodiale Verkettungen auf, bevor das Sympodialglied abgeschlossen wird.Die Pflanzen zeigen in allen Lebensphasen eine hohe vegetative Vitalität, dennoch läßt sich eine juvenil geprägte frühe Blüphase von einer älteren Blühphase (kürzere Zuwachseinheiten, Achsen‐ und Zuwachsdimorphismus) abgrenzen.Die Blütenstände (einfache/zusammengesetzte Rumpfcephaloide) stehen terminal und/oder seitlich an sylleptisch blühenden Seitenachsen. Sie werden als ‚florale Einheiten’︁ über ihre Lage zur Innovationszone vom ausdauernd‐vegetativen Bereich des Blühtriebes abgegrenzt.Aufgrund der hohen Variationsbreite (monopodiale/sympodiaie Zuwachsverkettung, einfache/zusammengesetzte Blütenstände, frühe/reife Blüphase, terminale und/oder seitliche Position von Blütenstanden) ist ein direkter Vergleich der einzelnen Arten schwierig. Mit Hilfe des ‚Blühtrieb’︁‐Konzeptes wird ein Gattungsmodell für Nebelia erstellt, auf das sich alle Arten beziehen lassen.
Inflorescence morphology of the Malayan species of Phyllagathis (Melastomataceae)
Authors: Weber A. 
Published: August 2010

AbstractThe five inflorescence types occurring in the Malayan species of Phyllagathis (which cover essentially the spectrum of the whole genus) are demonstrated to represent modifications and derivations of a monotelic (determinate), hom(oe)ocladic thyrse. The elongate, spike‐like thyrse (usually referred to as ‘panicle’ in the taxonomic literature) as found in P. griffiihii, P. stolonifera and P. cordata appears to be the most primitive type, from which – obviously independently – the ‘umbels’ of P. hispida and P. scortechinii have envolved. In the ‘umbel’ of the latter the central flowers (including the terminal flower) regularly fail to develop (truncation, polytelic organization!). The meristematic apex often extends to an oval or band‐like structure; this may divide into two or three portions and give rise to acrogeneous branching. Quite different ‘umbel’ types are found in P. tuberculata, P. magnifica (both with ‘compound umbels’ = globose or hemisphaerical thyrses with long‐pedunculate cymes) and P. stonei (‘simple umbel’ achieved by complete reduction of the cyme peduncles). In the ‘heads’ of P. rotundifolia and P. praetermissa a distinct involucrum is developed by the enlargement of the cyme bracts. The thyrses of Anerincleistus fruticosus are mostly reduced to fewflowered aggregates or solitary flowers. With regard to position, the epipetiolar displacement of the inflorescences onto a ‘phyllophore’ (P. cordata, P. scortechinii) is of particular interest.

AbstractThis work presents a practical application of the algorithm of the deductive method of syntaxonomic classification on trampled communities in the area of the Biosphere Reserve Křivoklátsko (Central Bohemia). By this procedure the communities were classed into units of a selected phytocenological system.Communities with predominant Anthemis cotula; Capsella bursa‐pastoris, Chamomilla recutita, Chamomilla suaveolens, Lepidium ruderale, Lolium perenne, Plantago media, Poa annua. Polygonum arenastrum, Potentilla anserina, Potentilla reptans, Urtica urens and other sporadically occurring trampled communities were evaluated. The text includes a description of the position of these communities in the frame of the phytocenological system and brief data on their synecology and distribution in the studied area.
A contribution to the study of three taxa of the genus Lupinus from North Greece
Authors: Drossos E. , Symeonidis L. , Karataglis S. 
Published: August 2010

AbstractThe relationships among three taxa of genus Lupinus (L. micranthus, L. albus subsp. graecus and L. angustifolius) from Northern Greece were studied.Data of morphometric parameters of fruits and seeds and peroxidase patterns of shoots suggest that: 1. The three studied taxa are separated and distinct. 2. L. micranthus is closer to L. angustifolius than to L. albus subsp. graecus. 3. L. albus subsp. graecus seems to possess a central position and to be equidistant from L. micranthus and L. angustifolius.
Die Samenbank unterschiedlicher Feuchtgrünland‐Gesellschaften Schleswig‐Holsteins und ihre Bedeutung für den Artenschutz
Authors: Drückhammer A. , Wried S. 
Published: August 2010

AbstractThe seedbank of widespread humid meadowland communities has been examined by means of germination experiments.The entire density of seed amounted between 6000 and 85000 (grains of) seed/mr2.On principle there were more species to be found in the seedbanks than in the covering of vegetation.Most species of the actual vegetation were also, registered in the seedbank. Supplementary species appeared, which have not appeared in the stocks of the testing areas. This is explained by their seedbank‐characteristics.Typical humid‐meadows species, which were missing in the rezent vegetation could be detected in the seedpotential as exceptions only.The examined seedbanks are dominated by a few species only. Juncus effusus predominated in almost all sampling areas.The correspondence of the species' spectrum with that of the seedbank is greater in the upper 4,5 cm ground than it is in the following layers. Only a few species show greater amounts of seed in deeper layers than close to the surface.For the restoration of humid meadows with a large number of species the seedbank of the examined stocks offers unfavourable conditions. This is due to its combination of species and the dominations within.

Published: August 2010

AbstractIn dieser Arbeit wird die Gattung Taeckholmia BOULOS 1967 mit Sonchus L. wiedervereinigt. Zum einen haben unsere morphologischen Nachuntersuchungen zahlreicher einschlägiger Arten der Kanarischen Inseln ergeben, daß die für Taeckholmia angegebenen diagnostischen Merkmale weder auf alle zu Taeckholmia gerechneten Arten zutreffen, noch auf diese beschränkt sind und also keine brauchbare Grenze zu den übrigen Sonchus‐Arten bilden. Zum anderen würden diese Merkmale, die nach BOULOS zwischen Sonchus und Taeckholmia unterscheiden sollen, eine neue Art, die kürzlich auf der Insel La Gomera gefunden wurde, Sonchus wildpretii U. & A. REIFENBERGER (REIFENBERGER 1992), sowohl der ersten als auch der zweiten Gattung zuordnen, wodurch diese Gattungstrennung unhaltbar wird.Dieser Einschluß in die Gattung Sonchus von Arten, die durch BOULOS der Gattung Taeckholmia zugeteilt wurden, macht eine Emendation der Untergattung Dendrosonchus SCH. BIP. ex BOULOS erforderlich.
Carpelloid stamens in Papaveraceae JUSS. and Brassicaceae BURNETT(Cruciferae JUSS.) and their bearing on theories of gynoecium organization
Authors: Brückner C. 
Published: August 2010

AbstractA rather frequent floral abnormality is the homeotic replacement of stamens with free carpelloid organs. This phenomenon is caused by spontaneous or experimentally induced recessive mutations. The morphology of carpelloid stamens in Papaveraceae and Brassicaceae taxa is described on the basis of the author's observations as well as literature analysis. The number of carpels constituting the gynoecia of these families has been much debated. One widely accepted theory claims that carpel number equals the number of placental regions (at least two—bicarpellary theory). Other hypothesis consider pistils with two placental regions to be formed by four carpels (tetracarpellary theory) or even six carpels (hexacarpellary theory). Also an “acarpellate” condition with the paracarpous gynoecia being intercalary tubes topped by carpel rudiments was postulated. The structure of carpelloid stamens, however, strongly indicates that the classical bicarpellary theory can sufficiently explain the organization of papaveraceous and cruciferous gynoecia. The features that seemingly gave hints for double or triple numbers of carpels are already displayed by a (theoretical or real) combination of two gynoecial units which are represented by perfectly carpelloid stamens.
Epidermal morphology of the genus Dialium (Fabaceae: Caesalpinoideae)
Authors: Sheteolu A. O. , Ayodele A. E. 
Published: August 2010

AbstractEpidermal morphology of adaxial and abaxial leaflet surfaces of the five species in the genus Dialium (Fabaceae: Caesalpinoideae) were studied by light microscopy. The epidermises are composed of cells which are isodiametric, irregular or both types in outline. Anticlinal walls are either straight, curved or undulate. Leaflets of all taxa are hypostomatic. Paracytic stomata occur in all species except D. guineense that posses both paracytic and staurocytic stomata. Other features of the epidermis that show variation include stomatal size and density, size and density of epidermal cells, and type, size, shape, frequency and basal cells of the trichomes. An indented, dichotomous key for identifying the species is presented.
