Discussion

Tragia ramosa is a variable species showing much environmental plasticity. Collections from the western United States and western Mexico have much broader leaves than those from Texas and Nuevo León, and were previously referred to as T. stylaris. Smooth stigmatic surfaces, three to six (rarely to ten) stamens, and narrow apical leaves are characters consistent with T. ramosa.
