Abstract

Based on molecular and morphological evidence, our results clearly indicate that Astragalus azizii should be reclassified as a member of the genus Oxytropis, representing a distinct species closely related to O. lapponica. In our molecular examination of the Astragalus sect. Brachylobium, we analyzed both the isotype and holotype of A. azizii and found that they were positioned among Oxytropis species in the nrDNA ITS-inferred phylogram. Through a detailed dissection of the flower, we observed the mucronate appendage on the keel petal — a diagnostic trait of the genus Oxytropis.

Abstract [Persian]

براساس شواهد مولکولی و ریخت­شناسی، نتایج ما به‌صراحت نشان می‌دهند که گونه‌ی Astragalus azizii به‌عنوان عضوی از جنس Oxytropis رده‌بندی می‌شود و گونه‌ای مجزا و خویشاوند نزدیکی از O. lapponica است. در حین بررسی‌های ما برروی بخش Brachylobium از جنس گون، نمونه‌های تیپ و ایزوتیپ گونه‌ی A. azizii آنالیز شد و درخت تبارزایی حاصل از توالی‌های nrDNA ITS نشان داد که این گونه در میان گونه‌های Oxytropis قرار می‌گیرد. تشریح گل بادقت انجام گرفت و زائده‌ی نوک تیز انتهایی برروی گلبرگ ناو مشاهده شد (صفت شاخص جنس Oxytropis).
