Abstract

Chromosome numbers are given for six taxa of Eremopyrum (Ledeb.) Jaub. & Spach (Poaceae) of Iran: E. bonaepartis var. bonaepartis (Spreng.) Nevski (2n=14 & 28), E. bonaepartis var. sublanuginosum (Drobow) Melderis (2n=28), E. confusum Melderis var. confusum Melderis (2n=28), E. confusum Melderis var. glabrum Melderis (2n=14), E. distans (C. Koch) Nevski (2n=14) and E. orientale (L.) Jaub. & Spach (2n=28). Chromosome numbers of six studied taxa were recorded for the first time from Iran.
