Discussion
Plants of Tragia betonicifolia resemble those of T. urticifolia but differ in the greater number of branches from the root crowns, the shorter length of the persistent staminate flower pedicel bases, the longer, narrower pistillate sepals, and the distally clustered arrangement of the staminate flowers.
Selected References
None.
