Recent botanical expeditions in Isfahan province led to the recollection of Rochelia retrosepala as a very rare and endemic species. Molecular data obtained from ITS nuclear sequences and trnL-F chloroplast sequences are presented to indicate its phylogenetic position in the genus. Based on the molecular results, R. persica is the closest relative taxon to the R. retrosepala. Some notes about the distribution and habitat of this rare species are presented. Furthermore, according to IUCN criteria and categories the conservation status of the species was assessed as Critically Endangered (CE).

Abstract [Persian]

انجام مطالعات گیاه‌شناسی اخیر در استان اصفهان منجر به جمع‌آوری مجدد Rochelia retrosepala ،گونه‌ای بسیار نادر و انحصاری شد. داده‌های مولکولی بدست آمده از توالی‌های هسته‌ای ITS و توالی‌های کلروپلاستی trnL-F برای نشان دادن موقعیت فیلوژنتیک این گونه در جنس ارائه می‌شود. براساس نتایج مولکولیR. persica ، نزدیک‌ترین خویشاوند به R. retrosepala است. برخی یادداشت‌ها در خصوص پراکنش و زیستگاه این گونه نادر ارائه شده است. همچنین، وضعیت حفاظتی آن بر اساس معیارها و دسته‌بندی‌های IUCN با درجه "در بحران انقراض" ارزیابی شد.
