78c. Poa araratica subsp. ianthina (Keng ex Shan Chen) Olonova & G. Zhu, Fl. China. 22: 306. 2006.

堇色早熟禾 jin se zao shu he

Basionym: Poa ianthina Keng ex Shan Chen in Ma et al., Fl. Intramongol. 7: 260. 1983; P. sinoglauca Ohwi.

Ligule 1–3 mm. Lemma keel shortly villous for 1/2 of length, marginal veins for 1/3, areas between veins pubescent; callus webbed or glabrous.

* Open grassy slopes, subalpine forest margins; 3300–4200 m. Gansu, Hebei, Nei Mongol, Qinghai, Shanxi, Sichuan, Xinjiang, Xizang, Yunnan.

The protologue of Poa sinoglauca reported the lemma to be pubescent on the intermediate veins. The type proved to have the lemma quite frequently pubescent both on the intermediate veins and on the area between the veins, and thus it is a better match with P. araratica subsp. ianthina.
