Discussion

A specimen of Bulbostylis capillaris collected by E. Hall (585) gives Oregon without a specific locality.

Bulbostylis capillaris is distributed over a broad range of physiographic types and occurs in many forms, the most distinctive of ours being var. crebra, which has, in addition to numerous longscaped anthelae, large numbers of spikelets at the plant base.
