TWO NEW SPECIES OF THE GENUS COUSINIA (ASTERACEAE) FROM IRAN

The genus Cousinia sect. Serratuloideae was revised in Iran to prepare the draft of Flora of Iran. Among the studied specimens two new species came to the light that are described in this paper. Cousinia farimanensis is described from NE Khorasan. It is similar to C. concolor, a species distributes in the northern part of the distribution of the new species. However, unlike C. concolor the leaves in the new species are discolor in the new species and also the involucral bracts are more numerous and with different characters. C. mehreganii is another new species that is a relative of C. euchlora. The two species are quite allopatric and differ in phyllaries and achene characters.
