Stems | viny, to 3 m, glabrous or sparsely to moderately pilose-pubescent, denser at nodes. |
Leaf | 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. |
Inflorescences | terminal, 1-flowered; bracts absent. |
Flowers | bell-shaped; sepals distally strongly spreading to recurved, violet-blue, lanceolate, 2.5-5 cm, margins proximally thick and tomentose, distally broadly expanded, 2-6 mm wide, thin, crispate, less conspicuously tomentose than proximal portion, or glabrate, tips acuminate, abaxially glabrous. |
Achenes | bodies appressed-puberulent; beak 2-3.5 cm, appressed-puberulent. |

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.) |
