Abstract :
Astragalus kazempourii is described as a new species from Firuzkuh in Tehran province, Iran. Morphological data and phylogenetic analyses of the nrDNA internal (ITS) and external transcribed spacer (ETS) regions places this species within sect. Hypoglottidei as sister of Astragalus parvarensis. The new species differs morphologically from A. parvarensis by having a short stem densely covered with basifixed hairs, short peduncles and a long calyx. A distribution map of the new species is provided and the habitat condition of the taxon and close relatives, as well as the conservation status of A. kazempourii are discussed. The phylogenetic analyses conducted also support the recent transfer of Astragalus bojnurdensis from A. sect. Brachylobium to sect. Hypoglottidei, which was in accordance with the morphological characters of this species.
Farsi abstract :
در اين مقاله Astragalus kazempourii به عنوان گونه جديدي از فيروزكوه در استان تهران شرح داده شده است. داده هاي ريختشناسي و تجزيه و تحليل تبارزايشي برپايه تواليهاي ITS و ETS هستهاي ريبوزومي (nrDNA) اين گونه را در بخشه Hypoglottidei و به عنوان گروه خواهري A. parvarensisقرار ميدهد. گونه جديد از نظر ريختشناسي، به واسطه داشتن ساقه كوتاه پوشيده از كركهاي ساده متراكم، دمگلآذين كوتاه و كاسه بلند از گونه خواهري خود A. parvarensis متمايز است. نقشه پراكنش A. kazempourii ارائه و شرايط زيستگاهي اين گونه و خويشاوندان نزديك آن و همچنين وضعيت حفاظتي آن بحث شده است. با درنظر گرفتن صفات متمايزكننده بخشه Hypoglottidei در مقايسه با بخشه Brachylobium به عنوان آرايه بسيار نزديك به آن، و نيز بر اساس شواهد مولكولي انتقال گونهA. bojnurdensis از بخشه Brachylobium به بخشه Hypoglottidei مورد تائيد قرار ميگيرد.
