Discussion | Clematis lasiantha is common in the Coast Ranges and the foothills of the Sierra Nevada of California. The Shasta used pounded stems or chewed or burned roots of Clematis lasiantha medicinally in the treatment of colds (D. E. Moerman 1986).

Clematis bigelovii is locally common and is restricted to New Mexico and a few sites in Arizona. Although usually grouped with C. hirsutissima because of its scarcely viny habit, this species appears to represent the extreme expression of clinal variation including C. pitcheri var. dictyota and, at the other extreme, eastern populations of C. pitcheri var. pitcheri; it might well be treated as C. pitcheri var. bigelovii (Torrey) B.L. Robinson. Clematis palmeri Rose is represented by a small number of specimens from New Mexico and one from eastern Arizona, and its distinctness as a species has been questioned. The few published descriptions scarcely suffice to indicate its distinguishing features and are sometimes at variance with each other and with specimens so identified by R.O. Erickson (1943) or others. Almost all specimens were found where C. bigelovii was reported nearby. Pending further studies, it seems likely that C. palmeri comprises somewhat aberrant specimens of C. bigelovii, C. hirsutissima var. scottii, and/or C. pitcheri var. dictyota, perhaps also some herbarium sheets of flowering and fruiting material inadvertently collected from different species, and/or hybrids involving the species named above in one or more combinations.
