How to use the site
There are several internet retrieval site about flowering plant which cover the genus. Taxonomic and Astragalus which give several correct and accessible names but never give ecological informative data set.
This site is planned for the biggest genus of Astragalus within 57 big genera in flowering plants which covers the classification and ecological informative data along with distribution pattern of species in different continents and countries of Old World according Evolutionary groups, sections and species order. All data will be extracted from a database set which is prepared since very long time. For the New world only Taxonomic hierarchy information will be retrieved from database.
In the present work, which is the continuation of “Astragalus in the Old World: the checklist” (Maassoumi, 1998). All sections were phylogenetically arranged (Maassoumi et al. 2017). Based on phylogenetic analysis, some sections and some synonymized entities were resurrected as distinct sections and species. Also, some species need to be rechecked. In this work, several species and resurrected sections were inserted, which have been recently published. All accepted data are based on molecular phylogenetic findings, Evolutionary trends, Inventory of species on the Geographical divisions of the Old World, then more information is available for subdivision of large areas such as: Asia, former USSR and Middle Asia.
All sections were arranged according phylogenetical new grouping of A, B, C, D, F, G ,H. Each group contains several sections which show Taxonomic affinities together. All species alphabetically arranged in sections with their synonyms.
Taxonomically, this site will be able to search the sections and species names which are inserted in browser lists according new grouping with their full synonyms in separate parts.
Supplementary notes such: species with gum duct, abbreviated with (G), poisonous species with Nitro- compounds (N+), selenium absorption (Se), chromosome number (n= : 2n= ) and other significant are indicated. Species which were recently published are marked with asterisk (*) and rare species (R). Comments of some taxonomists about systematic position of species or sections are given.
The site powerfully able to contribute the distribution pattern of sections and species of Old World in Europe, Asia (divided) and Africa continents and with using GIS finally will be dotted on Google earth map to show the distribution pattern.
All latitudinal and longitudinal data excluded from distribution pattern of species and some related maps of papers, revision works and Floras. For the New World species, only taxonomic data will be available.
