Stems | viny, to 3 m, glabrous or sparsely to moderately pilose-pubescent, denser at nodes. |
erect, not viny, 2-4(-6) dm, pubescent or pilose to ± tomentose or hirsute. |
Leaves | blade 1-2-pinnate or rarely a few simple or 3-foliolate; leaflets 4-10 plus additional ± tendril-like terminal leaflet, usually lanceolate to ovate, occasionally linear, unlobed or proximally 3-5-lobed, (1.5-)3-10 × (0.1-)0.4-4(-5) cm, thin, not conspicuously reticulate; surfaces glabrous, not glaucous. |

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.) |
Clematis albicoma is known only from shale barrens predominantly developed from the Upper Devonian Brallier Formation in nine counties of western Virginia and adjacent West Virginia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
