Stems | viny, to 3 m, glabrous or sparsely to moderately pilose-pubescent, denser at nodes. |
erect, not viny, 1.5-6.5 dm, hirsute (sometimes sparsely so in var. hirsutissima) or densely short, soft-pubescent to nearly glabrous. |

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. |
blade 2-3-pinnate; leaflets often deeply 2-several-lobed, if lobed than lateral lobes usually small and distinctly narrower than central portion, leaflets or lobes linear to lanceolate, 1-6 × 0.05-1.5 cm, thin, not prominently reticulate; surfaces sparsely to densely silky-hirsute, 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.) |
Varieties 2 (2 in the flora). The varieties of Clematis hirsutissima, although highly dissimilar in their extreme forms, intergrade extensively in Wyoming, Colorado, and Utah. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
