Abstract

As a result of our study on the genus Bromus, B. rigidus and B. sewerzowii are reported as new records for the flora of Iran. Bromus diandrus-rigidus complex comprises a group of species ranging from tetra- to octaploid levels, which have been treated in different ways.Based on a specimen from Golestan National Park, B. rigidus is reported along with its illustration and a comparison with its closely related taxa.Furthermore, B. sewerzowii is the second record that is based on a specimen from North Khorasan (Sarakhs). In addition, a taxonomic key to two the species and their allies has been presented.

Abstract [Persian]

این مقاله شامل گزارش دو گونه جدید از جنس Bromus L.  برای فلور ایران است. گونه Bromus diandrus-rigidusمجموعه‌ای پیچیده از گونه‌های تتراپلوئید تا اکتاپلوئید می‌باشد که پژوهشگران آنها را به طریق مختلف طبقه‌بندی می‌کنند. گونه‌ی B. rigidus با یک نمونه از منطقه جنگلی پارک ملی گلستان گزارش می‌شود و ضمن آن که با تاکسون های خویشاوند خود مقایسه خواهد شد تصویری از آن ارائه می‌گردد. همچنین گونه‌ی B. sewerzowii براساس نمونه‌ای از خراسان شمالی (سرخس) گزارش می‌‌شود. کلید شناسایی برای این دو گونه و گونه‌های نزدیک ارائه می‌گردد.
