Abstract

Astragalus leucargyreus Bornm. was the first time recollected from the type locality, Hamadan province after the 110 years. Morphological characters, habitat and geographical distribution are presented. Further studies showed that A. leucargyreus should be excluded from the sect. Hymenostegis Bunge and transferred to the sect. Adiaspastus Bunge, then treated as a synonymous with A. erythrolepis Boiss.. This study shows that A. leucargyreus Bornm.with its morphological feature as a valid species now is transferred from the sect. Adiaspastus to its previous the sect. Hymenostegis and excluded from synonymous status.

Abstract [Persian]

گونهBornm.  Astragalus leucargyreus  نخستین بار از محل تیپ، استان همدان، پس از گذشت 110 سال مجدداً جمع‌آوری شده است. ویژگی‌های مورفولوژیکی، زیستگاه و توزیع جغرافیایی آن ارائه می‌گردد. مطالعات قبلی نشان داد کهA. leucargyreus باید از بخش
Sect. Hymenostegis Bunge  خارج شود و به بخشSect. Adiaspastus Bunge  منتقل گردد، سپس به عنوان مترادف
 Boiss. erythrolepisA. درنظر گرفته شد. این مطالعه نشان داد کهA. leucargyreus   با ویژگی مورفولوژیکی‌اش در حال حاضر به عنوان یک گونه معتبر از بخش Sect. Adiaspastus به بخش قبلی خودSect. Hymenostegis  منتقل و از حالت مترادف خارج شود.
