Synonym: Tragia linearifolia Elliott
"Monoecious, perennial, rhizomatous herbs, armed with stinging trichomes. Leaves alternate, stipulate. Racemes axillary or terminal, or both, lowest 1 or 2 flowers pistillate, the upper staminate. Flowers greenish or purplish; petals absent; staminate flowers with 3-5 sepals and 2 or 3 stamens; pistillate with 3-8 sepals and 3 stigmas. Capsule 3-locular, 4-5 mm long, 7-8 mm in diam., each locule 1-seeded. Seeds light brown with darker mottling, or entirely dark brown, ovoid, 3-3.5 mm long; caruncle obsolete." 
"Plant 2-5 dm tall, freely branched. Leaves narrowly elliptic to oblanceolate or linear, 2-10 cm long, 0.2-2 cm wide, irregularly serrate, undulate or entire, base cuneate to attenuate; petioles 1-3 mm long. Racemes short or elongate, 0.3-12 cm long." 
In the Coastal Plain in Florida and Georgia, T. urens has been found in sand of open woodlands, pine uplands, fallow fields, annually burned pineland, sandhills, sand pine scrub, longleaf pine/wiregrass communities, and open pine savannas.  Associated species include longleaf pine, sand pine, and wiregrass. 
This species is thought to be dispersed by ants and/or explosive dehiscence.
