Heterocaryum is an herbaceous annual plant, covered with rough hairs and rarely glabrous, with single or branched stems, raised or lying on the ground, and native to the Gulf States. This study aims to find out taxonomic studies problem of the Heterocaryum genus and the new dispersal of species in Sar-e-Pol of Afghanistan and some province of Iran. It is a field and Laboratory research, based on the morphology and micromorphology characteristics like the length and thickness of fruit peduncles, the number of rows of glochids on the achene, and some other traits, on the 26 specimen was conducted at Bu Ali Sina University. According to the examination of the intended features of the collected samples of the genus Heterocaryum, a new identification key was provided, and based on the type specimens (Heterocaryum echinophorum (Pall.) Brand) was introduced in the flora of Afghanica for the first time from Sar-e-Pol Province of Afghanistan. The desired traits analysis by Principal coordinates analysis (PCO), and five species of the genus Heterocaryum were identified, consisting of three species from Afghanistan (H. echinophorum, H. rigidum, and H. x irregular) and two species from Iran (H. szovitsianum and H. subsessile). Suchtelenia and Heterocaryum are very similar plants and it would have been better to put them under one name. Both countries have a high density of species that make up a large part of spring and summer fodder for animals. At the some areas the high density of bushes prevents sudden floods.
