Discussion

Of conservation concern.

Clematis morefieldii is known only from limestone uplands east of Huntsville, Madison County, Alabama.

From all variants of the closely related Clematis viorna, C. morefieldii differs in the cobwebby tomentose as well as villous pubescence of its stems, and in having bracts at or very near the base of the peduncle rather than well above the base.
