Abstract

Astragalus lignipes (Fabaceae), a new species of sect. Dissitiflori will be described here based on morphological and molecular data (ITS and matK sequences). Our Maximum Parsimony and Bayesian Phylogenetic Inference analyses show that the new species is most closely related to A. aestimabilis, A. aucheri and A. xiphidium. It is characterized by long woody basal stems, chartaceous bracts and long pedicels. We provide information on the distribution and habitat of the new species with taxonomic notes about it and its sister taxa. We also assess the conservation status of the new species according to IUCN criteria as Critically Endangered.

Abstract [Persian]

Astragalus lignipes به عنوان یک گونه جدید از بخشه Dissitiflori براساس داده‌های ریخت‌شناسی و مولکولی (توالی‌هایITS و matK) شرح داده می‌شود. تحلیل‌های تبارزایی بیشینه صرفه‌جویی و بیزین ما نشان می‌دهد که گونه جدید، خویشاوند نزدیک گونه‌های A. aestimabilis, A. aucheri و A. xiphidium است. این گونه، به داشتن ساقه‌های قاعده‌ای بلند چوبی، براکته‌های کاغذی، و دمگل‌های بلند متمایز می‌شود. اطلاعاتی در خصوص پراکنش و زیستگاه گونه جدید به همراه نکات تاکسونومیک این گونه و خویشاوندان نزدیک آن ارائه شده است. همچنین وضعیت حفاظتی گونه جدید، مطابق معیارهای IUCN با درجه "در بحران انقراض" ارزیابی می‌شود.
