These specimens were previously identified as Ptilagrostis mongholica [= Stipa mongholica ] ( Bor 1960; Freitag 1985), but the two species are easily distinguished as P. dichotoma has a tuft of short hairs at the apex of anthers (glabrous in P. mongholica ). They are disjunctly distributed with P. dichotoma found in the mountains of southern-central Asia while P. mongholica occurs mainly in the mountains of northern-central Asia; ( Tzvelev 1968; Wu and Phillips 2006).
