Stipa borysthenica Klokov ex Prokudin View in CoL

Type:― UKRAINE. Lugov forest country house, Tyasmin, Aleks, u., 18 May 1911, I. Paczoski (lectotype selected by Tzvelev, LE!)

Stipa boryshtenica is a widely distributed taxon ranging from central Europe to central Asia ( Tzvelev 1976, Martinovský 1980, Conert 1998, Gonzalo et al. 2013) and is here reported for the first time from China. Having the ventral line of hairs at the anthecium at the distance of (1.6–)4.2–6.1(–7.7) mm not reaching the base of awn and almost glabrous to slightly scabrous vegetative leaves, S. boryshtenica is close to S. pennata View in CoL , however they differ by having callus base narrowly cuneate vs. pyriform, callus (3.4–)3.7–4.2(–4.6) vs. (2.4–)2.8–3.25(–3.75) mm long, upper cauline leaves (22–)36–62(–125) vs. (4–)10–22(–40) mm long respectively ( Klichowska & Nobis 2016). These two taxa also differ in the type of habitat in which they grow. Stipa borysthenica View in CoL grows generally on sandy grasslands and S. pennata View in CoL grows on steppe grasslands.

Specimens studied:— CHINA. Xinjiang: Fuyun county, Tuergen, elev. 1470 m., 6 June 1959, Xinjiang Exped. 10381 (PE-707071!, PE-707072!).
