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 viticella has also been reported from Quebec, New York, and Tennessee, but the reports have not been verified. It probably should be expected elsewhere.
