About
Clematis morefieldii is a rare species of flowering plant in the buttercup family known by the common names Morefield's leather flower and Huntsville vasevine.
It is endemic to northern Alabama and southern Tennessee, where it is known from about 22 populations currently, most of which are small. Many of the populations are threatened, and some have been recently extirpated. It is a federally listed endangered species, listed in 1992.
Where it grows
This species of Clematis was discovered in 1982, in a vacant lot on Round Top Mountain in Madison County, Alabama, by 21-year-old botany student James Morefield. It was described as a new species in 1987 and named for him. The plant was believed to be an Alabama endemic when it was given endangered status in 1992. Collections were later made in adjacent southern Tennessee.
