疏穗林地早熟禾 shu sui lin di zao shu he

Upper culm internode sometimes elongated, especially after flowering. Ligule of upper leaf 0.8–1.5 mm. Panicle effuse, 10–12 cm. Spikelets 3–5 mm; rachilla smooth or scabrid; callus glabrous or very sparsely villous.

* Meadows along forest margins; 1200–1600 m. Xinjiang.

In spite of the morphological resemblance to the hybrid complexes Poa lapponica and P. urssulensis, this variety seems to be closest to P. nemoralis. The glabrescence of the lemma callus and rachilla might be caused by mutation. Its status and relationship need to be defined more exactly.

Gatherings with a short ligule and unwebbed lemma callus, treated by Liu et al. (FRPS 9(2): 113. 2002) as Poa rhomboidea Roshevitz, might belong here. Poa rhomboidea is otherwise an endemic of limestone cliffs of the W Caucasus.
