A synopsis of Solanum subgenus Potatoe (G. DON) (D'ARCY) (Tuberarium (DUN.) BITTER (s. 1.))
Authors: Child Alan 
Published: August 2010

AbstractThe infrageneric taxa of the genus Solanum L. which seem to fit the concept of the subgenus Potatoe (G. DON) D'ARCY (1972) are reviewed. The sections are identified in a diagnostic key and are described with the more important species. The subgenus is evaluated as more or less discrete from other subgenera of Solanum but is drawn close to the genus Lycopersicon MILLER which is treated, for the purposes of this study, as a taxon of sectional rank. A new taxon, Lycopersicoides CHILD, is described as a subsection of the section Lycopersicon.

Published: August 2010

AbstractAn attempt has been made in this paper to compile a check‐list of the dicotyledonous plants in the flora of South Yemen on the basis of literature reports as well as several field trips to various localities in the country. In addition, herbarium collections available in the country were studied. In all 467 species belonging to 244 genera from 71 families are given in this check‐list. Further studies may reveal the occurrence of more species. It is hoped that this check‐list might serve as a step toward a comprehensive flora of South Yemen.
Stomatal types in the Umbelliferae in relation to taxonomy Tribes Coriandreae and Scandiceae
Authors: Ostroumova T. A. 
Published: August 2010

AbstractStomatal types of 14 species representing seven genera of the tribe Coriandreae and of 34 species of ten genera of the tribe Scandiceae were investigated, the species were mainly from the USSR flora. The tribe Coriandreae is rather homogenous as concerned to stomatal types, hemiparacytic and anomocytic stomata predominate; however, some exceptions are observed: in Schrenkia golickeana stomata are partly anisocytic and in Fuernrohria setifolia some stomata are diacytic; all the species have amphistomatic leaves. In the tribe Scandiceae diacytic stomata predominate or occur in significant frequency in many species, mainly belonging to the genera Chaerophyllum, Grammosciadium, Scandix. The rest of the species explored have anomocytic and rarely hemiparacytic stomatal types. In some species leaves are amphistomatic, in other species hypostomatic. Relevant taxonomic problems are discussed.
Phylogenetic and systematic value of stomata in Bicarpellatae (BENTHAM et HOOKER sensu stricto)
Authors: Gill L. S. , Nyawuame H. G. K. 
Published: August 2010

AbstractFoliar epidermal morphology and ontogeny of stomata are described for 320 taxa distributed in 13 families of the Bicarpellatae. The epidermal cells are generally straight‐walled in the woody taxa but sinuous in herbs and small shrubs. The different stomata types commonly described in the dicotyledons viz: anomocytic, anisocytic, paracytic and diacytic have been recognized during the present study. The families Acanthaceae and Labiatae are remarkable in showing only diacytic stomata generally regarded as the most advanced. The distribution, size and frequency of stomata could be used to establish systematic divisions and to suggest phylogenetic relationships within the Bicarpellatae. Ontogeny of stomata is uniform only in the family Oleaceae but heterogenous in all the other families. Evidence from stomatal ontogeny therefore appears to be taxonomically important only at the genus level. Single guard‐celled stomata, aborted stomata and contiguous stomata are of regular occurrence in the presently investigated families except the family Scrophulariaceae which showed no stomatal abnormalities. Adjacent stomata with cytoplasmic connections between their guard cells are of rare occurrence and such stomata are recorded in only six taxa distributed in the families Gentianaceae, Oleaceae and Solanaceae.
Vitalfärbung der Ölkörper der Lebermoose mit Diachromen und Fluorochromen
Authors: Müller‐Stoll Wolfgang R. , Ahrens Gerhard 
Published: August 2010

AbstractDurch Dimethylgelb (p‐Dimethylaminoazobenzol) in extrem verdünnter wäßriger Lösung werden die Ölkörper aller Lebermoos‐Arten voll vital angefärbt. Neutralrot bewirkt ebenfalls in stark verdünnter Lösung bei längerer Färbedauer eine elektive Rotfärbung der Ölkörper bei einigen Lebermoosen. Es handelt sich um eine elektro‐adsorptive Bindung von Farbkationen an der Oberfläche der Ölkörper und um Lösungsspeicherung im Innern. Rhodamin B bewirkt in prämortalem Zustand der Ölkörper ebenfalls eine elektive Färbung. Fluoreszenzmikroskopisch läßt sich mit Rhodamin B, Auramin, Acridinorange und Coriphosphin die Existenz einer solchen Hüllschicht nachweisen. Diese ist Träger spezifischer Adsorptionskräfte für die Farbkationen basischer Farbstoffe, enthält aber außerdem lipode Bestandteile, die eine Löslichkeitsspeicherung von Rhodamin B und wahrscheinlich auch der anderen Farbstoffe, wenngleich in viel geringerem Maße, bewirken. Die Ölkörper der Lebermoose besitzen eine plasmatische lipoidreiche Hüllschicht von besonderem Bau. Das Innere ist von einer nicht lebenden Emulsion aus einer öligen und einer wäßrigen Phase erfüllt.
Comparative anatomical characters of Periplocaceae follicles and their taxonomic significance
Authors: Dave Yash , Kuriachen P. M. 
Published: August 2010

AbstractThe fruits of Cryptolepis buchanani and Hemidesmus indicus are follicles. The fruit wall or the pericarp is distinguished into epicarp, mesocarp and endocarp. Epicarp is multilayered in both the fruits, composed of an epidermal layer and a collenchymatous zone of hypodermis. In H. indicus the collenchymatous zone is filled with tanniniferous contents. The mesocarp is parenchymatous. Vascular bundles are found overarched by cellulosic fibre bundles. Laticifers present in the mesocarp are non‐articulated. The lignified fibrous endocarp of Cryptolepis is thicker and harder than that of Hemidesmus. The follicles dehisce marginicidally. The pericarp anatomy of these two genera are compared with that of Cryptostegia grandiflora and a taxonomic key is also added to delineate these three genera.

Vegetative anatomy of Brachiaria obtussiflora (Hochst. ex A. Rich.) Stapf and Brachiaria callopus (Pilg.) Stapf (Poaceae)
Authors: Ogundipe O. T. , Olatunji O. A. 
Published: August 2010

AbstractThe microscope anatomy of the vegetative parts of B. callopus and B. obtussiflora is described for the first time. The investigations of these data have revealed a striking identity between the anatomical features of B. obtussiflora and Echinochloa. The similarity is so strong that we would not hesitate to suggest the placement of B. obtussiflora and not B. callopus in the genus Echinochloa on the basis of anatomical evidence. Anatomical evidence of B. callopus shows that it possesses similar anatomical characters with the species of Brachiaria and therefore should not be excluded from the genus Brachiaria.
A cluster analysis study on Cinnamomum from Kerala, India
Authors: Ravindran Shylaja , Balakrishnan R. , Manilal K. S. , Ravindran P. M. 
Published: August 2010

AbstractA cluster analysis study was carried out in Cinnamomum species occurring in the Kerala state of India with an aim of solving some of the taxonomic problems existing in the genus. Twentyeight collections (OTUs) representing eight species were used in the study. Twenty characters recorded from the OTUs were subjected to numerical analysis by single, complete and average linkage analysis. The OTUs were grouped using the centroid linkage technique. The cluster analysis of characters established the following character clusters: (i) bud type, stomatal type, phyllotaxy, and epidermal thickness (ii) hairiness, hair frequency and hair length (iii) inflorescence length, nature and type (iv) thickness of leaf, palisade, and spongy parenchyma and (v) leaf length and leaf breadth. The centroid linkage clustering has shown that C. camphora, C. perrottetti, C. riparium and C. cassia are very distinct types and hence formed independent clusters. C. malabatrum and C. veruum are closely related and formed close clusters. C. malabatrum is more complex having considerable intraspecific variability and hence ended up in more than one cluster, pointing to a need for a reexamination of this species.
The leaf anatomy of the species of Cochlospermum Kunth (Cochlospermaceae) in West Africa
Authors: Ogundipe O. T. , Olatunji O. A. 
Published: August 2010

AbstractThe leaf anatomy of the species of Cochlospermum Kunth occurring in West Africa is described. The stomata occur only on the lower surfaces of the leaves. The vasculature in the petiole is of medullated type in C. planchoni, while it is are with adaxial traces in C. tinctorium. Angular collenchyma is present in the petiole. Epidermis and mesophyll are uniseriate. Unicellular hairs occur on both surfaces of C. planchoni but vary in density. The two species can therefore be limited on the basis of anatomical characters.

Phenotypic plasticity and taxonomic significance in Thalictrum minus‐complex
Authors: Nikolić Toni 
Published: August 2010

AbstractThe presence of phenotypic plasticity may produce remarkable influences on the efficiency of usage of diagnostical characteristics and on the reality of hierarchical arrangements. In this paper the emphasis is on needfulness of lessening of taxonomic importance for some characteristics (plant height, number of leaflets, leaflet length, leaflet width) and enlargement of some other characteristics (number of leaflets incision, hairiness of upper leaflets side, lower leaflets side and hairiness of stalk) on the basis of displayed phenotypic plasticity caused through exposure of experimental groups to sun or shade.
Floral anatomy of six species of Impatiens
Authors: Devi D. Rama 
Published: August 2010

AbstractThe floral anatomy of six species of Impatiens has been studied. The hypogynous, tetracyclic, zygomorphic flowers are basically pentamerous. The posterior sepal bears a nectariferous spur. The stamens are connate by the filaments below the anthers which stand as a cap over the stigmas. The 5‐carpellary, syncarpous ovary is 5‐locular with many ovules in each loculus.The sepals, petals and stamens are single traced. Anatomy shows that the anterior perianth part is the product of adnation between the anterolateral sepals and anterior petal. The carpels are 3‐traced and the ovular supply is derived from the central core of vascular tissue in the placental region. The study supports the placement of Balsaminaceae in the order Geraniales.
Numerical taxonomy of the genus Erodium L'Hérit. (Geraniaceae) in Egypt
Authors: Naggar S. M. El 
Published: August 2010

AbstractMorphological data were acquired from herbarium and living specimens belonging to 14 native species of Erodium. Specimens were scored for 12 vegetative, 2 inflorescence, 18 floral and 17 fruit characters. The data were analysed using cluster analysis and which enabled the distinction of two main groups: Plumosa and Erodium. Plumosa group is classified into three subgroups: Crassifolea, Oxyrrhynchea and Glaucophyllea, while Erodium group is distinguished into five subgroups viz: Gruinea, Ciconea, Pulverulentea, Laciniatea and Cicutarea.

The leaf epidermal studies of some species of Aspilia Thouars (Asteraceae)
Authors: Ogundipe O. T. , Adegbite E. A. 
Published: August 2010

AbstractThe leaf epidermal surfaces of nine species of Aspilia Thouars were examined and described. The species are hypoamphistomatic and possess anomocytic and animocytic types, only a few species show the actinocytic type of stomata. The epidermal hairs (non‐glandular) are found and could be of diagnostic value. The nine species fall clearly into two artificial groups on the basis of the cuticular striations observed. The cuticular striations are present in A. bracteosa, A. linearifolia, A. rudis, A. bussei and A. spenceriana; and absent in A. africana var. africana, A. africana var. ambigua, A. helianthoides, A. kotschyi var. kotschyi, A. kotschyi var. alba and A. paludosa. Also prickle‐like unicellular hairs occur in A. kotschyi var. alba, A. helianthoides and A. bracteosa. A key based on epidermal characters is proved for the identification of the species studied.
Chemosystematics of the Sapindaceae
Authors: Umadevi I. , Daniel M. 
Published: August 2010

AbstractNineteen members of the Sapindaceae have been screened for their foliar flavonoids, phenolic acids, tannins, saponins and alkaloids. The family is heterogeneous in its chemical constitution. The Aceraceae and Hippocastanaceae are merged with the Sapindaceae. The intra‐familial classification of the Sapindaceae by Radlkofer gains support from the chemical data. Dodonea is found to be very distinct from the rest of the family and therefore the creation of a separate subfamily Dodoneoideae is suggested. Filicium decipiens finds a proper place in this family.

Dimension analysis of Thymelaea hirsuta (L.) ENDL. fibers
Authors: Shaltout K. H. 
Published: August 2010

AbstractThe present study indicates the abundant occurrence of two types of fibers (bark and xylem fibers) in the stem tissues of the evergreen circum‐Mediterranean shrub T. hirsuta. The bark fibers have cellulosic walls, and are much longer, and narrower in diameter and lumen. The means of these variables are 3329, 12.6, and 6.9 microns respectively. On the other hand, xylem fibers have lignified walls. The means of their length, diameter, and lumen are 824, 13.9, and 7.8 microns respectively. The frequency distribution of the length of both types of fibers are presented. The fiber dimensions of this plant are comparable to those of many soft and hardwoods, and more suitable, from the papermaking point of view, than those of bagasse and rice straw: the main local materials for the production of paper in Egypt.
Floristic elements and distribution pattern in the flora of Chotanagpur (Bihar) India
Authors: Agarwal Vijayluxmi , Paul S. R. 
Published: August 2010

AbstractEight types of floristic elements are recognized in the flora of Chotanagpur Plateau (23.5°–24° N lat. and 83°–86° E long.) Bihar, India. The Eastern‐South Eastern‐Australian element (57 sps.–30.97%) has been found to be dominant. Six taxa are endemic to the region. Six main types of distribution patterns, mainly based on PAUL's (1991) study on phytogeography of Netarhat (Chotanagpur), Bihar has been recognized. The study reveals that montane plants have stronger links with north‐eastern and southern regions.

Leaf architecture in relation to taxonomy: Meliaceae
Authors: Sarma Vijayalakshmi , Raja Rao S. Shanmukha , Beena C. H. 
Published: August 2010

AbstractLeaf architectural features in nine genera and eleven species of the Meliaceae have been studied. The major venation pattern conforms to pinnate camptodromous either with eucamptodromous or brochidodromous and mixed craspedodromous types. The highest degree of vein order is up to 7°. Leaf architectural characteristics such as the presence of major venation categories, nature of the marginal ultimate venation, areoles, presence or absence of bundle sheath and the type of leaf margin are found to be helpful in delimiting the taxa studied. Accordingly, a key is prepared for the identification of the species investigated.
Response on photosynthetic pigments to drought and salt stress in some desert species
Authors: Elhaak M. A. , Migahid M. M. , Wegmann K. 
Published: August 2010

AbstractThe effect of drought and NaCl osmotic stress were tested on the pigment contents of the desert species Gymnocarpos decandrum, Ononis vaginalis, Plantago albicans and Zygophyllum album. Samples of these species were collected from their habitats in the north‐western desert of Egypt and from plants grown in the green‐house under different levels of osmotic stress. The pigment contents decreased with drought stress but increased with salt stress with varying degrees in the four species. Chlorophyll b was more sensitive to drought stress than chlorophyll a. Higher pigment contents were recorded in the widely distributed species than in the less distributed ones. Chlorophyll a, b and carotenoids exhibited higher tolerance to salt stress than to drought.
Frequency and distribution of wood rays in several conifers. With 6 Figures and one Table
Authors: Schultze‐Dewitz G. 
Published: August 2010

AbstractThe paper deals with the behaviour of parameters of wood rays over stem's transverse section as to be found in selected publications as well as in their continuance over the stem length according to own additional investigations. Considered are height, number and portion of uniseriate rays in peripherical wood of the mature tree species Pinus silvestris L., Picea abies, (L.) KARST., Pseudotsuga menziesii (MIRB.) FRANCO, Larix decidua MILL., and Taxodium distichum RICH. With increasing tree height ray height decreases, number of rays more or less increases, and ray portion decreases only with Pinus silvestris and Picea abies.
Floristic evaluation of anthropopressure zones in Warsaw With 5 Figures
Authors: Sudnik‐Wójcikowska B. , Moraczewski I. R. 
Published: August 2010

AbstractIn the present work the results of floristic investigations conducted in Warsaw for over a period of 10 years were used. The city area was divided into 225 squares. Each square was assigned to one of the four anthropopressure zones A, B, C, D which were distinguished with respect to the gradually decreasing intensity and duration of man's impact. The work attempts to find the best floristic reflection of the anthropopressure zones. For each square both the floristic lists and the previously defined complex indices of flora synanthropization were analyzed.The use of complex indices instead of entire flora is associated with the inevitable reduction of informations which may be selected intentionally.Seven different ways of classifying the squares according to the anthropopressure intensity: A‐B‐C‐D, A‐B‐(CD), A‐(BC)‐D, (AB)‐C‐D, (AB)‐(CD), A‐(BCD), (ABC)‐D were compared with the floristic classifications. These classifications were compiled using the cluster analysis in which both the entire flora and complex indices were used.Assessing the similarities between classifications it is possible to draw conclusions about the sensitiveness of indices and flora as a whole to change due to man. Floristic value of the borders between the anthropopressure zones A‐(BCD) or between (AB)‐(CD) is the greatest. In general, the indices reflect the anthropopressure zones better than the entire flora.
