Revision of the Section HololeuceBunge of the Genus AstragalusL. ( Leguminosae) in Turkey.

We revised the section Hololeuce Bunge of the genus Astragalus L. (Leguminosae) in Turkey. The section used to contain 20 taxa in Turkey, but in this study it has been reduced to 15. A new species (Astragalus dumanii Ekici & Aytaç) has been described. In addition, we concluded that A. vuralii H.Duman & Aytaç, A. cylindraceus DC., A. alindanus Boiss., A. paecilanthus Boiss. & Heldr. and A. squalidus Boiss. & Noë are synonyms of A andrasovszkib Bornm., A. globosus Vahi, A. hirsutus Vahl, A. sibthorpianus Boiss. and A. amoenus Fenzl respectively. The pollen grains are tricolporate, prolate, subprolate or prolate sphaeroidal and the ornamentation is reticulate. [ABSTRACT FROM AUTHOR]
