Clematis hirsutissima Pursh var. hirsutissima[FNA3, HC2]
Douglas' clematis
Publication: Fl. Amer. Sept. 2: 385. 1814.
Origin: Native
Herbarium search: CPNWH
Notes: FNA3: "..some plants from Washington, Oregon, Colorado, and elsewhere have leaflets quite as narrowly lobed, and other plants in the Flagstaff area have more widely lobed leaflets. The widely spreading leaves allegedly characteristic of C. hirsutissima var. arizonica likewise occur elsewhere in the range of the species. Clematis hirsutissima var. hirsutissima , as circumscribed here, is highly variable in the density of leaf pubescence throughout most of its range."
