Discussion | Melica ciliata is grown as an ornamental in North America and is not known to have escaped. It is native to Europe, northern Africa, and southwestern Asia, where it grows on damp to somewhat dry soils. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Melica harfordii grows primarily in the Pacific coast ranges from Washington to California, as well as in the Sierra Nevada and a few other inland locations, usually on dry slopes or in dry, open woods. The awns in M. harfordii often escape attention because they do not always extend beyond the lemma. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
