This is a variable species with a wide range of spikelet size, but usually with clearly unequal, purple glumes and awnless lemmas. The name
Agrostis sikkimensis refers to slender, delicate variants with small spikelets and very fine leaf blades, often growing among moss on rocks. There is continuous variation to taller forms with larger spikelets growing in meadows and woodlands. Forms with a short, straight, subapical awnlet (
A. limprichtii,
A. lushuiensis) may have arisen by hybridization with
A. sinorupestris.
Agrostis szechuanica (Y. C. Tong ex Y. C. Yang) L. Liu (Vasc. Pl. Hengduan Mts. 2: 2247. 1994; A. clavata Trinius var. szechuanica Y. C. Tong ex Y. C. Yang, Bull. Bot. Res., Harbin 4(4): 99. 1984) may belong here. The type, from Sichuan (Hanyuan), has not been seen. It is also reported from Yunnan.
