Tragia leptophylla
Tragia leptophylla is known from the western part of the Edwards Plateau region in west-central Texas. K. I. Miller and G. L. Webster (1967) did not recognize T. leptophylla as a distinct species; they treated it as a synonym of T. ramosa. Tragia leptophylla differs from T. ramosa in its less branching habit, dark reddish stems, usually entire leaf blade margins, fewer staminate flowers per inflorescence, and riparian limestone cobble habitat.
