Discussion

Southern Texas is the northernmost distribution of Tragia glanduligera. In Mexico, it is found in tropical deciduous forests in Campeche, Nuevo León, Tabasco, Veracruz, and Yucatan. This species and T. jonesii are the only species in the flora area with stipitate glands on the inflorescence. Tragia glanduligera differs from T. jonesii by its leaf blade margins with 10–15 smaller teeth per side, shorter staminate pedicels, and truncate to weakly cordate leaf blade bases.
