SEM studies of foliar epicuticular wax morphology in some taxa of Euphorbiaceae With one Table and 6 Plates
Authors: Kulshreshtha K. , Ahmed K. J. 
Published: August 2010

AbstractThe wax morphology of 16 species belonging to 13 genera of the family Euphorbiaceae have been studied by scanning electron microscopy. Six main types of wax, i.e., granular, crystalloid plates, ribbon, crust, rod‐shaped, and aggregate type, have been observed. The predominant types are fine granules and crystalloid plates. In several species, however, the wax is sparse or inconspicuous. The present study is not elucidate a clear pattern of relationships between wax morphology of Euphorbiaceae and its taxonomic divisions at sub‐family and tribal level made by some workers. However the studies indicates considerable diagnostic value of way morphological characters ad inter and intra‐generic level.
Habitat features and plant communities of the Holy places, Makkah, Saudi Arabia With 3 Figures and one Table
Authors: El‐Ghani M. M. Abd 
Published: August 2010

AbstractThe present study is an attempt to assess the effect of the environmental factors on the pattern and distribution of the plant communities in the Holy places area in Makkah, Saudi Arabia. Wide variation in topography and soil characteristics have a marked influence on the water resources and consequently on the vegetation. Eleven plant communities recognized by species dominance and habitat features have been distinguished. These include four communities dominated by trees and shrubs, five communities dominated by suffrutescent species and two are dominated by ephemerals. The floristic composition and the habitat features are described and the ecological relationships between the communities are briefly discussed.

Current situation of the raudha's woody plant populations in the Central Saudi Arabia With 3 Figures and 3 Tables
Authors: Shaltout K. H. , Mady M. A. 
Published: August 2010

AbstractThis study evaluates the size‐frequency distribution of six trees and shrubs (Tamarix aphylla, Ziziphus spina‐christi, Calotropis procera, Ricinus communis, Lagonychium farctum, and Lycium shawii) in two raudhas in the Central Saudi Arabia, in order to diagnose their current situation in relation to the prevailing environmental factors. The populations of five species had positively skewed size distributions which may represent rapidly growing populations with high reproductive capacity, and hence the long term stability. On the other hand, the population of Lycium shawii had a bell‐shaped distribution, therefore if its current situation continues, a reduction in its size is expected in the future. However, all the examined populations except those of Tamarix aphylla and Ziziphus spina‐christi seem to be under environmental stress.

Taxonomy of Phyllantheae: A chemical point of view
Authors: Hemalatha A. , Radhakrishnaiah M. 
Published: August 2010

AbstractThe distribution pattern of phenolic acids in 12 species of Phyllantheae is studied. The chemical data show a similarity between Flueggea microcarpa and the species of Phyllanthus. F. microcarpa and F. leucopyrus appear to be conspecific, but they are chemically different. The treatment of Bridelia and Cleistanthus in one group to the exclusion of Glochidion is supported.
Floral anatomy and systematic position of Flindersia R. BR
Authors: Lal Sheela , Narayana L. L. 
Published: August 2010

AbstractThe floral anatomy of Flindersia australis, F. bourjotiana, F. dissosperma and F. schottiana, has been studied. The flower is bisexual, regular, 5‐merous, 5‐cyclic and hypogynous. The sepals are 3‐traced and lateral traces of adjascent sepals arise conjointly. The petals are single traced. There is adnation between the petal midribs and antipetalous staminodal traces. The androecium in Flindersia consists of five fertile stamens and five vascularised staminodes. The massive and annular disc is non‐vascularised and is present between the androecium and gynoecium. The ovary is 5‐carpellary, syncarpous and 5‐locular. The carpels are 3‐traced. Dorsal carpellary traces are suppressed. Judging from the position of the homocarpellary ventrals, the placentation is interpreted as axile. The style is vascularised by the homocarpellary ventrals and terminates in five conduplicate stigmas. It is tentatively suggested that Flindersia along with Chloroxylon can be segregated into an independent family, Flindersiaceae and the family can be considered as a connecting link between Meliaceae and Rutaceae.

A phytogeographical comparison between subalpine forests of Guatemala and Costa Rica
Authors: Islebe G. A. , Kappelle M. 
Published: August 2010

AbstractWe conducted a comparative study on the phytogeographical similarities between the vascular generic floras of subalpine forests in Guatemala and Costa Rica. In total 178 vascular plant genera in 80 families were recorded in Central American subalpine forests, with 103 in Guatemala and 127 in Costa Rica. Woody genera account for less than 30% in subalpine Guatemala and over 50% in subalpine Costa Rica. The Guatemalan subalpine flora consists mainly of wide temperate, holarctic and neotropical herb genera, whereas the Costa Rican subalpine flora is principally made up of neotropical shrub and wide tropical tree genera, next to a small amount of wide temperate herb genera. Almost 30% of the 178 vascular genera are shared between both Central American subalpine floras, resulting in a Sørensen Coefficient of Community of 45%. The major part of the shared flora (57%) is temperate in distribution, the holarctic element being twice as important as the austral‐antarctic element. In conclusion, we state that since the formation of the Panamanian Isthmus plant migration from the holarctic region into subalpine Costa Rica dominated over migration from the austral‐antarctic region towards subalpine Guatemala.
Micromorphological studies of original and mutant cultivars of ornamentals
Authors: Datta S. K. , Shome U. 
Published: August 2010

AbstractFour original Chrysanthemum, two Rose cultivars and Lantana depressa and their respective gamma ray induced flower colour/chlorophyll variegated mutants were selected for the study of micromorphology of petal/leaf surfaces. Differences were observed among the original and mutant cultivars in cell shape, cell boundaries, cell wall surface and striations. The observations revealed a lot of finer details of petal surface, not only among the original and mutant cultivars but also between the cultivars. Studies clearly indicated that petal micromorphological characters can be utilized not only for identifying the mutants but also a comparative study will help the proper identification of different present day cultivars of Chrysanthemum and Rose and their origin.

Die Anamorphe ist nur schwer von den Anamorphen anderer auf Caragana parasitierenden Microsphaera‐Arten zu unterscheiden. M. palczewskii scheint in den verholzten Teilen der Wirtspflanze perennieren zu können. Neben morphologischen Untersuchungen werden auch die Verbreitung und Ausbreitung innerhalb Europas beschrieben und kurz diskutiert.
Effect of cement dust on petal morphology of Brassica campestris L
Authors: Misra J. , Pandey V. , Ahmad K. J. 
Published: August 2010

AbstractEffect of cement dust on petal morphology of Brassica campestris L. was studied under light and scanning electron microscopes. In control (undusted) plants, papillae were striate and coronulate with clear boundaries unlike dusted plants where they were shrunken and collapsed. Number of papillae was also reduced. Cement dust absorbed moisture from petal surface causing water loss and subsequent loosening of the arrangement of papillae. Damage to flower petals will affect the quality of flowers thus causing serious losses in floriculture.
Notes on the Oak‐hornbeam forest communities of the Czech Republic
Authors: Neuhäuslová Z. , Kolbek J. 
Published: August 2010

AbstractBy the revision of the phytocenological material from the oak‐hornbeam forests a new subassociation. Melampyro‐Carpinetum vincetoxicetosum, has been distinguished. It is linked‐up to the warmer and steeper slopes with mesotropic brown earths in the hilly countries of the Czech Republic. This community is compared with the related subassociations Melampy‐ro‐Carpinetum festucetosum heterophyllae (KLIKA 1939) NEUHÄUSL 1982 and Melampyro‐Carpinetum primuletosum veris (MIKYŠKA 1963) NEUHÄUSL 1982. The new unit is documented by phytocenological releves and synecological characteristics.
The desert vegetation communities of the Lower Volga Valley
Authors: Golub V. B. 
Published: August 2010

AbstractThe present paper is a continuation of a set of investigations aimed at description of the Lower Volga valley vegetation (GOLUB and MIRKIN 1986; GOLUB and ČORBADZE 1989; GOLUB et al. 1991). The paper covers desert vegetation communities formed on ecotopes which are not or unimportantly affected by floods and ground waters. Two new classes have been determined i.e. Artemisietea lerchianae (communities on loamy‐sandy and loamy soils) and Artemisietea tschernievianae (communities on sandy soils). Floristic composition syntaxa of lower rank is dependent on pasture load intensity, sod deterioration degree and height of ecotopes position above a lower water level of the water streams.
Pollen morphology of Cicer L. ‐ wild and cultivated annual species
Authors: Chaturvedi M. , Yunus D. , Datta K. 
Published: August 2010

AbstractPollen morphological studies have been carried out in all the annual species of Cicer L. including four varieties of the cultivated species C. arietinum, using LM and SEM. Pollen grains are 3‐zonocolporate with large lolongate endocolpia in C. arietinum, C. cuneatum, C. judaicum, C. pinnatifidum, C. reticulatum and C. yamashitae, and 3‐parasyncolporate in C. bijugum, C. chorassanicum and C. echinospermum. Exine surface ornamentation in these species is reticulate, fossulatereticulate or pitted at the mesocolpium. In case of reticulate exine surface, the number of lumina/cm2 counted at the mesocolpium has been used as an additional parameter for delineating the species. A pollen morphological similarity between the wild species C. reticulatum and the cultivated species C. arietinum with respect to apertural feature and exine surface ornamentation supports the view of LADIZINSKY and ADLER (1976a, b), that the former species could be the possible wild progenitor of the cultivated chickpea.
Monerma P. BEAUV. (Poaceae) – not an illegitimate name
Authors: Scholz H. 
Published: August 2010

AbstractThe two names Hainardia and H. cylindrica proposed in 1967 for the widely distributed Mediterranean taxa so far known under Monerma and M. cylindrica are to reject as illegitimate in favour of the latter names, both legitimate, well‐established and used in taxonomic literature. Some modern trends intending the protection of illegitimate names are critically reflected in brief.

An analysis of the early floral development of Pittosporum tobira (THUNB.) AITON and some remarks on the systematic position of the family Pittosporaceae
Authors: Erbar C. , Leins P. 
Published: August 2010

AbstractIn Pittosporum tobira all floral organs are initiated in a strictly acropetal succession. It is striking that sepals and petals show an extremely early hyponastical development. Important floral characters for placing the family Pittosporaceae near the Apiales (Araliaceae and Apiaceae) are the early sympetaly, only gradual differences in the gynoecium development and placentation, and the fact that a nectar secreting area is situated at the base of the dorsal carpel flanks (ovary superior in Pittosporaceae, inferior in Apiales).Viscid latex, which plays an important role in the dispersal of the seeds by exozoochory, is produced by the multicellular epidermal hairs in the septal (placental) region.
Die morphologische Vielfalt der generativen Diasporen – Präsentation eines Lehr‐ und Lernschemas
Authors: Hilger H. H. , Hoppe J. R. 
Published: August 2010

AbstractIn einem vor allem für Lehr‐ und Lernzwecke gedachten Schema wird in zweidimensionaler tabellarischer Form ein Überblick über die strukturellen Möglichkeiten der Angiospermen gegeben, generative Diasporen zu bilden. Berücksichtigt werden die Merkmale Gynoeceumstyp/Diasporentyp/Perikarpanatomie. Dabei sind die Diasporen (mit Spring‐/Streu‐ und Schließfrüchten) gegen die morphologischen Gestaltungsmöglichkeiten des Gynoeceums (chori‐/coenokarp und ober‐/unterständig) aufgetragen. Die Tabelle zeigt, wie die Angiospermen in der Lage sind, aus unterschiedlichen Teilen des Gynoeceums und der Blüte sowie Blütenständen gleiche Funktionstypen zu erzeugen. Nicht berücksichtigt werden die Ausbreitungsweisen, die in der tabellarischen Darstellungsweise den morphologischen Möglichkeiten in der dritten Dimension überlagert wären. Nur sehr wenige Gestaltungsmöglichkeiten finden keine Entsprechung.
Spergulo morisonii–Corynephoretum canescentis (Frühlingsspark‐Silbergrasflur) – Lebensstrategien von Binnendünen‐ und Lockersandbesiedlern
Authors: Frey W. , Hensen I. 
Published: August 2010

AbstractIm Spergulo morisonii‐Corynephoretum canescentis (Frühlingsspark‐Silbergrasflur; Typische Variante undCladonia‐Variante) sind drei Lebensstrategien von biologischer Relevanz: die der Einjährigen Pendler, die der Besiedler mit Fern‐ und Nahausbreitung und die der Chamaephytischen Ausdauernden mit Fern‐und Nahausbreitung.Bei den Einjährigen Pendlern tritt die übersandungsunempfindliche AssoziationskennartSpergula morisonii, die Nahausbreitung mit generativen Diasporen aufweist und eine mächtige Diasporenbank aufbaut, bestimmend auf. Bei den Besiedlern bedingen vor allem das SilbergrasCorynephorus canescensund die LaubmoosePolytrichum piliferumundCeratodon purpureusdie hohen Gruppenmengenanteile, bei den Chamaephytischen Ausdauernden sind es die strauchigen FlechtenCetraria aculeataundCladoniauncialis. Diese Arten zeigen ein ausgeprägtes klonales Wachstum und Reproduktionsverhalten. Hierdurch vermögen sich die Arten effektiv auszubreiten und zu regenerieren.Die beiden Varianten unterscheiden sich durch die Anteile Besiedler/Chamaephytische Ausdauernde. In der Typischen Variante dominieren die Besiedler (BFNg,kl) mitCorynephorus canescens, in derCladonia‐Variante treten die Chamaephytischen Ausdauernden (ChAFNkl) in den Vordergrund. Dies ist auf die stabileren Oberflächenverhältnisse zurückzuführen.

Authors: Seine R. , Porembski S. , Barthlott W. 
Published: August 2010

AbstractOn the basis of extensive fieldwork, a first survey of carnivorous plants occurring on inselbergs is provided. Inselbergs are mostly dome‐shaped granitic or gneissic outcrops with scarce vegetation cover. They are important habitats for carnivorous plants in wooded tropical areas. Three families of carnivorous plants (Droseraceae, Lentibulariaceae, Nepenthaceae), including four genera and 45 species are reported from various inselberg habitats. Carnivorous plant families and genera are represented on inselbergs proportionally to their importance in the regional species pool.
On the genera Hammatolobium FENZL and Tripodion MEDIK. (Papilionaceae, Loteae s. 1.)
Authors: Tikhomirov V. N. , Sokoloff D. D. 
Published: August 2010

AbstractThe comparative analysis of the morphological features in Tripodion and Hammatolobium shows that they cannot be treated as members of the same genus. Tripodion tetraphyllum and Hammatolobium are considered to differ from each other in both of the features used by LASSEN (1986) to distinguish the genera Tripodion s. l. (incl. Hammatolobium) and Anthyllis s. str. T. tetraphyllum has dehiscent and not lomentaceous fruits and differs in this important character from Hammatolobium as well as from Anthyllis s. str. The standards of Hammatolobium lotoides and H. kremerianum differ from the standard of T. tetraphyllum and resemble the ones of certain species of Anthyllis. Two subgenera of Hammatolobium are accepted.
