Description
"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." [1]
"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." [1]
Distribution
Ecology
Habitat
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 (FSU Herbarium). Associated species include longleaf pine, sand pine, and wiregrass (FSU Herbarium).
Phenology
It has been observed flowering in April and May and fruiting May through September (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by explosion mechanisms or by ants. [2]
