TAXONOMIC REVISION OF THE GENUS VICIA L. (FABACEAE) IN IRAN

The Iranian materials of the genus Vicia were reviewed. A critical study of 500 specimens collected for this study and additional herbarium specimens led to reporting a new subspecies, V. villosa Roth. subsp. dasycarpa (Ten.) Cav. from Iran. In addition, recollection and identification of two species, V. mollis and V. lathyroides which were not deposited in any of the Iranian herbaria before. According to the results of this study 15 sections within the Iranian materials of Vicia were recognized. Also the following changes were applied: revival of two sections Crocea and Lenticula; transferring the members of sect. Cassubicae to sect. Vicilla; V. koeieana from sect. Anatropostyla to sect. Ervilia; V. hirsuta from sect. Ervum to sect. Ervilia; V. crocea from sect. Vicilla to sect. Crocea; recognition of the subgen. Cracca. Four new synonymes made: subgen. Vicilla as synonym of subgen. Cracca; sect. Cassubicae as synonym of sect. Vicilla; V. sojakii as synonym to V. ciceroideae; V. michauxii var. stenophylla as synonym to V. michauxii. Furthermore, V. lutea var. lutea is deleted from the flora of Iran and V. canescens is recognized as its sensu lato with no infra-specific taxa in. A taxonomic key to the Vicia taxa is presented here.
