A taxonomical monograph of Anemia subgenus Anemiorrhiza (Filicinae)
Authors: Duek J. J. 
Published: August 2010

AbstractThe morphology of the specimens contained in the herbaria B, P, S and US were studied. The subgenus Anemiorrhiza comprise 12 taxa(2 infraspecific) 3 hybrids and have 12 synonyms. Descriptions, keys and distribution by countries are given. A set of characters is postulated as a pattern of variation (state variables) for the genus Anemia. And based on it a numerical classification under information theory is presented. A modified WAGNER'S tree is hypothesised to account for the branching secuence and the amount of divergence between the species of the subgenus Anemiorrhiza.

Published: August 2010

AbstractEingehend beschrieben und abgebildet werden aus dem baltischen Bernstein Jungermannia berendtii sp. n. und Radula sphaerocarpoides sp. n. J. berendtii sp. n. ist der erste paläontologische Nachweis der Gattung Jungermannia L. s. str. und der Jungermanniaceae s. str. überhaupt. Sie gehört wahrscheinlich zu Jungermannia Sekt. Desmorhiza AMAK. Durch Übersehen des Unterlappens war Radula sphaerocarpoides sp. n. früher als Jungermannia sphaerocarpoides CASPARY 1887 (non J. sphaerocarpoidea DE NOT. 1859) von CASPARY beschrieben worden. Das Zusammenvorkommen von Radula sphaerocarpoides sp. n. mit Frullania acutata CASPARY und Lejeunea latiloba CASPARY im selben Bernsteinstück belegt erstmals ein Bruchstück einer eozänen Mooszönose. R. sphaerocarpoides sp. n. ist der zweite paläontologische Nachweis der Radulaceae.
Taxonomy, Distribution and Ecology of the Canadian Labiatae
Authors: Gill L. S. 
Published: August 2010

AbstractThe author presents the distribution maps of all the known species of the Labiatae occurring in a wild state in Canada. Sixty eight species and nine hybrids of this family are recognized to occur in Canada. Generic and specific keys are given. The bioclimatic requirements for each taxon are discussed. The native species are grouped into four categories: (1) Species of widespread occurrence in Canada and there are eight such species. (2) Species mainly distributed in southeastern climatic region of Canada and these are 15 species in this category. (3) Prairie species. This includes 6 taxa. (4) Species restricted to Pacific climatic region and there are only three species. The introduced species are grouped into three categories: (1) Naturalized and widely distributed and this includes 11 species. (2) Naturalized and restricted in distribution, but established and persisting. There are 23 taxa in this group. (3) Species of sporadic occurrence which do not usually persist for a long time and this category includes 11 taxa. It is also concluded that 12 species do not occur in Canada as no specimen could be traced to support the record and these should be excluded from the Canadian Labiatae.
Über Fagetea im kartalinischen Kaukasus
Authors: Passarge Harro 
Published: August 2010

AbstractAus dem zentral‐transkaukasischen Bergland (800–2200 m NN) an der Grusinischen Heerstraße werden folgende Assoziationen (strukturelle Zusammensetzung, Untereinheit, Standort) beschrieben: Orobo‐, Dentario‐, Polysticho‐, Petasito‐, Veratro‐ und Myrtillo‐Fagetum orientalis (Tab. 1–5). Die überregionale Geltung der ermittelten Höhenstufen‐und Trophiegliederung bestätigt ein Literaturvergleich. Trotz mancher Analogien zu korrespondierenden Fagus sylvatica‐Ass. in Mitteleuropa überwiegt das Trennende (s. Tab. 6). Der Affinität ihrer Artengruppen entsprechend werden die kaukasischen Fageten zu den Verbänden Rhododendro‐ und Vaccinio‐Fagion orientalis in der Ordnung Rhododendro‐Fagetalia orientalis zusammengefaßt.

Taxonomic studies of the genus Ageratum L. in India
Authors: Sahu T. R. 
Published: August 2010

AbstractTwo species of the genus Ageratum L., viz., A. conyzoides and A. houstonianum are rather poorly distinguished morphologically. The former which has sparsely hairy involucre bracts and light blue heads is distributed throughout India. The latter is known to occur in Northern parts of the country and has densely hairy bracts and blue heads. Polygraph constructed on the basis of taximetric analyses of 16 quantitative characters, revealed significant similarities in most of the characters. They were also found similar in trichome types, the details of these have been discussed by the author (1979). On the basis of these studies it appears that two species which are not very clearly distinguishable, may better be merged together into one species and A. houstonianum may be treated as variety houstonianum of the species A. conyzoides.
Vegetation of inland desert wadies in Egypt. II. Wadi El‐Matuli and Wadi El‐Qarn
Authors: El‐Sharkawi H. M. , Fayed A. A. , Salama F. M. 
Published: August 2010

AbstractTorrential rains (in January 1980) that had suddenly swept a limited area in the eastern desert facing Qena Province (Upper Egypt) resulted in enriching the vegetation of some extremely dry wadies at this location. Vegetation survey carried out shortly after this event (in April) revealed the prevailance of annuals which are hardly recognizable in such usually dry habitats and in considerable abundance. The normally scarce perennial vegetation has flourished too. The investigation reveals that the wadies studied are potential shelters of 3 community types, one of which seems to be a segetal part of an “Alliance” wide‐spread in other wadies of this desert. Distribution of such vegetation units seems to be controlled by relative aridity of the soil as well as by soil depth.
Zur Kenntnis der Fruchtmorphologie der Papaveraceae Juss. s. str. und der Hypecoaceae (Prantl et Kündig) Nak
Authors: Brückner Claudia 
Published: August 2010

AbstractBasierend auf vergleichend‐morphologischen Untersuchungen an 20 Papaveraceae‐Gattungen wird eine Beschreibung der Fruchtmorphologie (incl. Anatomie) für jede Gattung gegeben. Bei 4 Gattungen konnte lediglich auf Angaben aus der Literatur zurückgegriffen werden. Für die 4 Triben sind bestimmte Kombinationen von Differenzierungsmerkmalen charakteristisch. Besondere Beachtung fanden dabei die Struktur der äußeren und inneren Perikarp‐Epidermis, die Chlorenchym‐Verteilung, der Verlauf der Milchröhren, die Gynoeceumsvaskulatur und die Dehiszenzform. Die homokarpellaten Platystemoneae (Unterfamilie Platystemonoideae) sind von den heterokarpellaten Papaveroideae klar abgegrenzt. Die Chelidonieae sind u. a. nach den Dehiszenzformen die plastischste Tribus, hier finden sich zahlreiche ursprüngliche Merkmalsausprägungen. Die sich explosiv akropetal öffnenden Kapseln der Eschscholzieae sind anatomisch relativ einheitlich. In den Papavereae treten nur unvollständig basipetal dehiszierende Früchte auf, die durch fehlende Valvendorsalnerven und im Phloëm verlaufende Milchröhren charakterisiert sind. Bestimmte Strukturen weisen auf nähere Bezichungen zwischen Einzelgattungen hin, jedoch rechtfertigt dies keine taxonomische Neugliederung der Familie. Die Hypecoaceae stehen den Chelidonieae (Glaucium, Dicranostigma) und den Eschscholzieae nahe. — Ein phylogenetisches Schema zeigt die karpomorphologischen Beziehungen in den Papaveraceae.

Trichome studies in Parthenium hysterophorus and their taxonomic importance
Authors: Sahu T. R. 
Published: August 2010

AbstractIn Parthenium hysterophorus L. four trichome types i.e. (1) cylindrical hair, (2) moniliform hair, (3) simple multiseriate hair and (4) shaggy hair, have been recognized mostly on the basis of their structural differences. In the past, these types have not been observed in any species of Parthenium studied so far. Out of these four, two types i.e. cylindrical and moniliform hairs are known to occur in the Compositae and remaining two i.e. simple multiseriate and shaggy hairs are the new forms for the family and have been observed for the first time in presently investigated species. Trichomes are an important taxonomic tool in distinguishing between genera and species. Trichomes of the different species of Parthenium as noticed from their structure are useful in distinguishing these species and even their corresponding organs.

Chemosystematics of some Indian members of the tribe Phaseoleae (Fabaceae)
Authors: Dutt C. B. S. , Daniel M. , Sabnis S. D. 
Published: August 2010

AbstractTwentysix members belonging to the tribe Phaseolae (Fabaceae) have been analysed for their leaf flavanoids, phenolic acids, alkaloids and saponins. It is found, that all the subtribes within, possessed district assortment of chemical characters and therefore their elevation to tribes ist supported. Clitoria and Butea, being chemical dissimilar to other members of the Glycineae and Erythrineae, find a proper place in Euphaseoleae (Tribe Phaseoleae of Hutchinson) and Galactieae respectively. The varietel status of Teramnus labialis var. mollis ist upheld and the status of a separate species is recommended for Rhynchosia minima var. laxiflora Bak.

The significance of the three independent ‘Kew’ editions of JOHNSON'S Gardener's Dictionary
Authors: Mabberley D. J. 
Published: August 2010

AbstractThe various editions of JOHNSON'S Gardener's Dictionary (1846–1917) are discussed and the three ‘Kew’ editions (1882, 1894, 1917) examined in the context of contemporary horticultural and botanical publications, notably those issued by nurserymen and botanic gardens. Besides some 280 additions to Index kewensis and Index filicum, there are numerous changes in authorities of currently used species names, a change in Acalypha and restoration of Cyrtanthus × hybridus, while new combinations in Canistrum and Rhododendron and a new name in Maytenus are proposed.
Taxonomy of medicinal plants I. Epidermal morphology of the genus Khaya (Meliaceae) in West Africa
Authors: Olowokudejo J. D. , Nyananyo B. L. 
Published: August 2010

AbstractLeaf epidermal morphology of four West African species of Khaya (Meliaceae) has been studied using both light and scanning electron microscopy. The cuticle may be striate, reticulate or verrucose. Epidermal cells are either isodiametric or irregular in shape. The anticlinical walls are of variable thickness and their positions are marked by raised ridges or shallow irregular grooves. Periclinal walls may be flat, concave or convex.Anomocytic stomata which are either superficial or slightly sunken occur in all taxa. Stomatal size and index are variable among all species. A dichotomous key for identifying the species, even if they are in a fragmentary condition, is presented.
Studies on the cystoliths of Acanthaceae
Authors: Inamdar J. A. , Chaudhari G. S. , Rao T. V. Ramana 
Published: August 2010

AbstractThe occurrence, type of cystoliths, their size and frequency are worked out in 46 species belonging to the family Acanthaceae. Cystoliths are observed in all species, except in seven species belonging to tribes Thunbergieae, Nelsonieae, Acantheae and Justicieae. Cystoliths are classified into eleven types. They are mostly solitary, elongated, narrow or broad, pointed or blunt at one or both ends. However, double and rarely triple cystoliths are also observed. The size of the cystoliths varies even in the same species. The length/breadth ratio varies insignificantly for the species. The frequency of cystoliths in the Acanthaceae manifests conformity within a genus. However, the characteristics of the cystoliths may not be profitably used as a taxonomic tool.

Authors: Perrino P. , Maruca G. , Lester R. N. , Linsalata V. , Lattanzio V. , Hanelt P. 
Published: August 2010

AbstractChemotaxonomic investigations of leaf flavonoids by paper chromatography have shown that the cultigen Vicia faba is very distinct from the wild species V. hyaeniscyamus, V. johannis, V. serratifolia, V. narbonensis, V. galilaea and V. bithynica: the progenitor of V. faba remains unknown. No significant differences in chromatographic profiles were found between ten accessions of Vicia faba, which ranged from primitive land‐races to advanced cultivars, but there were highly significant differences between growth chamber and field grown plants.

The validity of the classical cenotaxonomic method has thus been demonstrated.
Fruchtanatomische Studien an Dictamnus albus L., Zanthoxylum simulans Hance, Ptelea trifoliata L. und Ruta graveolens L. (Rutaceae)
Authors: Brückner Claudia 
Published: August 2010

AbstractDie Frucht von Dictamnus albus besteht aus freien, an der Basis untereinander verwachsenen Karpellen, Zanthoxylum simulans hat chorikarpe Früchte, Ptelea trifoliata besitzt synkarpe Früchte, und bei Ruta graveolens werden die Früchte nach der Anthese vollständig synkarp, während die freien Griffeläste postgenital fusionieren. Die Perikarp‐Anatomie wird vergleichend analysiert und illustriert. Die histologischen Bedingungen für die Kombination aus ventrizider und loculizider Dehiszenz bei Dictamnus und Zanthoxylum sowie die loculizide Dehiszenz von Ruta werden dargestellt. Das Vaskulaturmuster in der Ventralregion weicht zum Teil etwas von dem für die Fruchtknoten zur Anthesezeit in der Literatur beschriebenen ab. Die karpologischen Merkmale werden diskutiert und ihre Aussagekraft für systematische Aussagen eingeschätzt. Zwischen Dictamnus und Ptelea gibt es eine größere Anzahl fruchtanatomischer Gemeinsamkeiten. Das unterstützt den in der Literatur gemachten Vorschlag, Ptelea in die Unterfamilie Rutoideae zu überführen. Für eine engere Verwandtschaft von Ruta und Dictamnus, wie sie sich im System von Engler (1931) widerspiegelt, können karpologisch keine Beweise erbracht werden.
Floral anatomy of some Melastomataceae
Authors: Satyavathi D. V. L. , Narayana L. L. , Devi D. Rama 
Published: August 2010

AbstractThe floral anatomy of five taxa of Melastomataceae, namely, Memecylon edule, M. guinensis, M. capitellatum, Rhexia marina and Tabouchina semidecandra has been studied. The regular, epigynous flowers are tetramerous in Memecylon edule, M. capitellatum, Rhexia marina and pentamerous in M. guinensis and Tabouchina semidecandra. The floral parts as well as their traces show varying degrees of adnation. The septate condition of the ovary in Rhexia marina and Tabouchina semidecandra and the presence of rudimentary septa in Memecylon edule, M. guinensis and M. capitellatum reveal that the central placentation in the family is derived from axile or anatomically parietal ancestry. The carpels are 3‐traced in Memecylon edule, M. guinensis and M. capitellatum and 5‐traced in the rest. The style is vascularized by the dorsal bundles in Memecylon species and by the common median laterals in Rhexia marina and Tabouchina semidecandra.
Features of foliar epidermis and stomata in eight species of Alternanthera (Amaranthaceae)
Authors: Mohan A. Ch. , Raju Vatsavaya S. 
Published: August 2010

AbstractThe features of mature foliar epidermis and stomata are described in eight species of Alternanthera. They showed diversity as regards the size of the epidermal cells and the nature of anticlinal walls; the stomatal size, frequency, index and basic type also varied. The epidermal cells are generally polygonal or irregular in outline while the anticlinal walls are usually sinuous, occasionally undulate or arched. The stomatal size varied from 20.3 × 13.6 μm (A. bettzichiana) to 37.4 × 18.8 μm (A. philoxeroides). Rather unusually, within the eight taxa examined, the genus showed as many as three basic stomatal types, namely, diacytic, paracytic and anisocytic.
Gradient analysis of canal vegetation in Nile delta region
Authors: Shaltout K. H. , El‐Sheikh M. A. 
Published: August 2010

AbstractThe present study aims at evaluating the behaviour of 15 common weeds, distributed along the net of canals and drains in the Middle Delta region, in relation to environmental gradients of some soil variables.Some species have significant simple correlations (either positive or negative) with certain soil variables (salinity, CaCO3, nitrogen and organic matter). Some other species have monomodal behaviours along some soil gradients, while all the examined species have bimodal behaviours along, at least, one soil gradient. The possible reasons that could be lead to bimodality were discussed.

Published: August 2010

AbstractOn the basis of quantified data, involving distribution of foliar free amino acids in eight taxa of Indian Sida, it is inferred that they show only a distant kindship. The cluster analysis based on the amino acid profiles also reveals that S. rhombifolia ssp. rhombifolia and S. rhombifolia ssp. retusa warrant their elevation to the rank of individual species.
