Discussion | As with many other members of the subgenus, the leaves of Clematis drummondii are reputedly used in a poultice to treat irritations of the skin in humans and other animals. Clematis coahuilensis D. J. Keil is found in central and north-central Mexico in habitats similar to those of C. drummondii; it is distinguished by ovate, entire to 3-lobed, leathery leaflets.

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).
