There are several internet retrieval site about flowerning plant which cover the genus

Taxonomic and Astragalus which give several correct and accecible 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 patter 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.


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.

With their synonyms.All species alphabetically arranged in sections

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.

Number of species with absorbing the soil Selenium marked (Se) or producing Nitro compound compositions (N+) will be poisonous for kettles. In case of (N-) indicate palatable for the kettles. Several woody species in cross section showing different size of gum duct, which produce the gum which are marked as (G).

Chromosome numbers of some species were given in haploid or diploid

Endemic species will be retrieve according different continents and the countries of eachThe    including Iran, Turkey, Afghanistan ane ….etc continent For example: from Asia you can


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.


View statistics summarising the contents of Old World and New World taxa which are indicated in separate tables and showing the number of species, Endemics and richness in each areas od the continents In Europe, Asia, Africa.
