Discussion | Clematis lasiantha is common in the Coast Ranges and the foothills of the Sierra Nevada of California. The Shasta used pounded stems or chewed or burned roots of Clematis lasiantha medicinally in the treatment of colds (D. E. Moerman 1986).

Clematis crispa is highly variable in leaflet width, and conspicuous variation may occur on a single plant (R.O. Erickson 1943); no discontinuity or geographic correlation exists that would permit the recognition of varieties. The dilated, petaloid sepal tips and thin, crispate, broadly expanded sepal margins are diagnostic for this species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
