We describe a new species, Poa probatovae Olonova et Chepinoga, which occurs in the conifer forests of Tunkinskiye Goltsy Ridge (East Sayan Mts.) in the south of Republic of Buryatia (Eastern Siberia). Besides the protologue, we indicate the affinity of the new species and its geographical distribution. Assumptions about a possible relationship of P. probatovae are made as well. The new species is close to P. × intricata Wein (P. palustris L. × P. nemoralis L.) and P. remota Forcell but differs well from them by glabrous callus of the lemma, pubescence between the veins of lemma and between keels of palea. The described species is presumably endemic for Tunkinskiye Goltsy Ridge, but it is very likely found on other ridges of East Sayan Mts. and the Khamar-Daban Ridge.
