硬质早熟禾(原变种) ying zhi zao shu he (yuan bian zhong)

Poa kelungensis Ohwi, Acta Phytotax. Geobot. 4: 60. 1935; P. palustris Linnaeus var. strictula (Steudel) Hackel; P. sphon-dylodes var. kelungensis (Ohwi) Ohwi; P. strictula Steudel.

Panicle quite dense, branches short, erect, with spikelets crowded from base. Spikelets 3.5–5 mm.

Open sandy ground, frequently on river banks, meadows among scattered thickets on slopes, grassy places on sunny slopes; 100–2500 m. Anhui, Hebei, Heilongjiang, Henan, Jiangsu, Jilin, Liaoning, Nei Mongol, Sichuan, Taiwan [Japan, Korea, Russia (Far East)].

The type and other gatherings of Poa kelungensis, which are quite soft and with the uppermost internode almost equal to its blade, closely resemble the type of P. sphondylodes. Gatherings from sandy beaches are quite different from typical P. sphondylodes, but those from shady forests are closely allied and form intermediate populations. The extreme form probably represents a discrete (maybe apomictic) population, which cannot be treated without more research. The type of P. strictula and most gatherings so named represent a mesomorphic form of P. sphondylodes.
