Abstract

Alyssum minus (L.) Rothm. var. minus is recorded for the first time from Iran. Alyssum minus (L.) Rothm. var. mazandaranicum Pakravan & Bolourian is described as a new taxon from the North and West of Iran. The four varieties of Alyssum minus in Iran (A. minus (L.) Rothm. var. minus, -var. strigosum (Banks & Sol.) Zohary, -var. micranthum (C.A.Mey.) Dudley and - var. mazandaranicum Pakravan & Bolourian) based on their morphological, palynological and anatomical characters were studied and compared with A. desertorum Stapf and A. szowitsianum Fisch. & Mey., from the same section. Although a great similarity observed in morphological characters and many intermediate specimens especially between the varieties of A. minus var minus and -var. micranthum (C. A. Mey.) Dudley was found, due to anatomical differentiation in sclerenchymatous cells and palynological differences in pollen size and shape, the varieties of Alyssum minus (L.) Rothm. were distinguishable.

Abstract [Persian]

واریته Alyssum minus (L.) Rothm. var. minusبرای اولین بار از ایران گزارش می‌شود. واریته­ای جدید (Alyssum minus var. mazandaranicum Pakravan & Bolourian) از شمال و غرب علاوه بر واریته­های موجود در ایران (A. minus (L.) Rothm. var. minus, -var. strigosum (Banks & Sol.) Zohary, -var. micranthum (C.A.Mey.) Dudley ( معرفی می‌شود و صفات ریخت­شناسی، گرده­شناسی و تشریحی جهت یافتن ویژگی­های جداکننده یا مترادف­کننده این چهار واریته بررسی و با دو گونه دیگر از همان بخشه یعنی A. desertorum Stapf و A. szowitsianum Fisch. et C. A. Mey. مقایسه می‌شوند. شباهت قابل توجهی در صفات ریخت­شناسی وجود داشت و افراد حدواسط زیادی به ویژه در بین دو واریته A. minus var. minus و -var. micranthum (C. A. Mey.) Dudley مشاهده گردید. با این حال به دلیل اختلافات موجود در شکل و اندازه دانه­گرده و تفاوت­های تشریحی در سلول­های اسکلرانشیمی، می توان واریته­های Alyssum minus (L.) Rothm. را از یکدیگر تشخیص داد
