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.
