72b. Poa sphondylodes var. erikssonii Melderis in Norlindh, Fl. Mongol. Steppe. 1: 99. 1949.

多叶早熟禾 duo ye zao shu he

Poa longiglumis Keng ex L. Liu; P. plurifolia Keng.

Ligule 2–3 mm. Panicle branches with spikelets in distal 1/2. Spikelets 3.5–5(–5.5) mm; palea sometimes pubescent between keels.

* Meadows among scattered thickets on slopes, grassy places on sunny slopes. Hebei, Henan, Nei Mongol, Shaanxi, Shanxi, Sichuan.

This variety is closer to Poa palustris in its shorter ligule than to typical P. sphondylodes, so it might be of hybrid origin. The variability of this variety depends very much on environment, and both the leaf characters and the panicle characters appear to vary. The panicles of the same clone may differ greatly in the shape, length, and width of their branches when grown in the wet seasons or when the habitat turns dry. The type of P. longiglumis is very close to this variety.
