阿拉套早熟禾(原亚种) a la tao zao shu he (yuan ya zhong)
Poa breviligula Keng ex L. Liu; P. densissima Roshevitz ex Ovczinnikov; P. juldusicola Regel; P. festucoides N. R. Cui (1987), not Lamarck (1791); P. litvinoviana Ovczinnikov; P. sinattenuata Keng; P. sinattenuata var. breviligula Keng; P. parafestuca L. Liu; P. poophagorum Bor subsp. hunczilapensis Keng ex D. F. Cui.
Culms 6–20 cm tall, scabrid. Leaf blade folded or inrolled, 0.5–1 mm wide; ligule 1–2(–3.5) mm. Panicle oblong, narrow, dense to quite loose, 2–4 × 0.5–1.5 cm; branches 2 or 3 per node, basal primary branch 2/7–2/3 as long as panicle. Spikelets lanceolate, never viviparous; rachilla smooth or pilulose; lemma lanceolate to narrowly lanceolate, keel shortly villous for 1/2 of length, marginal veins for 1/3, other parts glabrous; callus glabrous. 2n = 28.
Alpine grassy places; 2000–5200 m. Gansu, Qinghai, Shaanxi, Sichuan, Xinjiang, Xizang, Yunnan [India, Kazakhstan, Kyrgyzstan, Mongolia, Nepal, Pakistan, Russia (Altay), Tajikistan, Uzbekistan].
The types of both Poa densissima and P. juldusicola match P. albertii subsp. albertii well. The type of P. litvinoviana seems to be of hybrid origin and resembles both P. attenuata and P. glauca, so it should be assigned to P. albertii. The types of both P. sinattenuata and its var. breviligula differ from P. albertii subsp. albertii only by the pilulose rachilla, but rachilla indumentum is too variable within this hybrid complex to be a reliable basis for recognizing even subspecies. The type of P. parafestuca has not been seen, but descriptions and other gatherings show that it should be assigned to subsp. albertii.
