The Sections Of Astragalus L. With Bifurcating Hairs In Iran, Farrokh Ghahremaninejad
The Sections Of Astragalus L. With Bifurcating Hairs In Iran, Farrokh Ghahremaninejad
Turkish Journal of Botany
In this study Astragalus L. with bifurcating hairs in sectional levels in Iran are discussed (subgenus Cercidothrix Bunge). This subgenus has more than 800 species in the Old World. Major areas of species endemism for this subgenus occur in Turkey, Iran, Kazakhstan and Afghanistan. Iran, with 158 species, is one of the most important centres of diversity. Leucocercis Bunge is the only endemic section for Iran, although other sections have some species in different countries. Thus having a knowledge of the distribution quality in other areas is also important. In reality, this study is part of the author's research on …
Possibility Of An Information System On Plants Of South-West Asia With Particular Reference To The Turkish Plants Data Service (Tubives), M. Teki̇n Babaç
Possibility Of An Information System On Plants Of South-West Asia With Particular Reference To The Turkish Plants Data Service (Tubives), M. Teki̇n Babaç
Turkish Journal of Botany
For quick and accurate access to information about a flora of a country it is becoming increasingly important to develop databases. Databases developed and provided by international organisations are expensive to use and difficult to maintain without outside help. It is therefore important for developing countries to develop their own plant databases best suited to their requirements. One such example is the Turkish Plant Data Service (TUBIVES), designed by Turkish systematists. This database is described with some samples, and the possibility of creating a South-West Asian Plants Information Service (SWAP-IS) is briefly discussed.

Computer Technology For The Future Of Sw Asiatic Botany, R. J. Pankhurst
Turkish Journal of Botany
Much computer software already exists for floristic and monographic studies. Database software can hold all the data required for a Flora, and can process it much more accurately. The fundamental data tables are those for names, authorities, people, specimens, bibliography, geography and distribution. To these can be added other data such as descriptions, keys, images, maps, chromosomes and vernacular names. The same data system can be used for collection management and making herbarium labels. It is very important to use data standards such as for books, journals and authorities. Computerised descriptions and keys can also be constructed and held in …

A New Record For The Flora Of Turkey: Ambrosia Tenuifolia Spreng. (Compositae), Lütfi̇ Behçet
Turkish Journal of Botany
Ambrosia tenuifolia Spreng. (Compositae) is a new addition to the flora of Turkey from Malatya (in the East Anatolia region). The specimens collected from Malatya have different properties from the known diagnostic characteristics of the species. A. tenuifolia is a monoecious plant without glands. Its female capitula are in the axils of the upper leaves in its original description, but some of our specimens have only female capitula (female capitula in terminal racemes and lower parts of the racemes bracteate, but upper parts ebracteate) and there are many glands particularly on the tops of their fruits. The diagnostic characteristics, ecology …

Value Of Trichome Characteristics For The Separation Of Bifurcating Hairy Astragalus L. (Fabaceae) At The Sectional Level, Farrokh Ghahremaninejad
Turkish Journal of Botany
The attachment of hairs in sections of Astragalus L. may be either basal or lateral (bifurcate). This study focuses on Astragali with bifurcating hairs in the Old World (subgenus Cercidothrix Bunge). In this study, it appears that the ratio of hair arm length, and hair form and length are usually stable at the sectional level. The proposition of uniting some sections based on morphological characters is confirmed by hair characters; for example, uniting sections Tamias Bunge, Acantherioceras Rech. f. and Pseudoerioceras Ulzijchutag with Erioceras Bunge. The most important characters in the separation of the sections are macromorphological, but hair characters …
