Discussion
Danthonia californica grows in prairies, meadows, and open woods. It has a disjunct distribution, one por¬tion of its range being located in western North America, the other in Chile. An introduced population has been found at Mansfield, Massachusetts.
Plants with pilose foliage have been called Danthonia californica var. americana (Scribn.) Hitchc. and plants with sparsely pilose lemma backs D. californica var. macounii Hitchc, but the variation does not appear to be taxonomically significant.
