Discussion

Plants of Tragia smallii are easily distinguished from those of most Tragia species by the combination of orbiculate to elliptic leaf blades, two stamens, and relatively large seeds. K. I. Miller and G. L. Webster (1967) placed it and T. urens, which also has two stamens, in sect. Leptobotrys.

Tragia smallii is found on the Gulf Coastal Plain from eastern most Texas to peninsular Florida.
