Discussion | 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.) |
Although widely cultivated because it is the only species of Clematis with truly red flowers, C.texensis is native only to the southeastern part of the Edwards Plateau, Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
