辨析
This species has sometimes been considered conspecific with Stipa koelzii (a synonym of S. capillacea in this treatment), but it has much larger glumes lacking filamentous tips and more clearly pubescent, non-spiralling awns. It also grows in drier habitats.
本种有时已经被考虑了同种的具Stipa koelzii(在这次处理过程中的一S. capillacea的异名), 它也在干燥生境里增长。
