Discussion
Plants of Tragia urticifolia are easily distinguished from those of other non-glandular North American members of Tragia by the persistent bases of its staminate pedicels, which are long-extended beyond their subtending bracts. Although similar to T. betonicifolia, T. urticifolia has fewer stems, shorter pistillate sepals, inflorescences with fewer staminate flowers that are not distally clustered, and leaf blades with very light green abaxial surfaces.
