Journal Article 2019 12 23 Original meiotic chromosome numbers are reported for seven species in four families of mosses from Iran including: <em>Amblystegium serpens</em> (n=19), <em>Anomodon rugelii</em> (n=11), <em>Didymodon tophaceus</em> (n=13), <em>Drepanocladus exannulatus</em> (n=11), <em>Eucladium verticillatum</em> (n=11), <em>Fissidens viridulus</em> var. <em>tenuifolius</em> (n=10) and <em>Grimmia pulvinata</em> (n=13). Chromosome count for <em>Fissidens viridulus </em>var.<em> tenuifolius</em> is reported here for the first time. Report for five other species are new for flora of Iran. شمارش کروموزومی در تقسیم میوزی برای هفت گونه متعلق به چهار تیره از خزه‌های ایران به قرار ذیل گزارش می‌شود:<br /> Amblystegium serpens (n=19), Anomodon rugelii (n=11), Didymodon tophaceus (n=13), Drepanocladus exannulatus (n=11), Eucladium verticillatum (n=11), Fissidens viridulus var. tenuifolius (n=10) and Grimmia pulvinata (n=13).<br /> شمارش کروموزومی گونه Fissidens viridulus var. tenuifolius (n=10) برای اولین بار گزارش می‌شود. گزارش پنج گونه دیگر برای فلور ایران جدید می‌باشد. https://ijb.areeo.ac.ir/article_121899_7b74ee0f880440931c618575510e3c2d.pdf
