Synonym: T. urticaefolia.[1]
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."[2]
"Plants 2-6 dm tall, stems strict or little branched, often reclining. Leaves triangular-ovate, 2-6 cm long, 0.7-4 cm wide, simply or doubly serrate, base truncate to subcordate; petioles 5-15 mm long. Racemes 1-4 cm long."[2]
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, T. urticifolia can be found in limestone glades, recently burned pine-oak woods, longleaf pine forests, and in pine savannas.[3] It has been recorded to grow in sandy loam and clay loam soils.[3][4]
Associated species include shortleaf pine, red oak, post oak, mockernut hickory, and longleaf pine.[3]
Phenology
T. urticifolia has been observed flowering May through July and in September and fruiting in June and September.[3][5]
Seed dispersal
This species is thought to be dispersed by ants and/or explosive dehiscence.[6]
Fire ecology
Populations of Tragia urticifolia have been known to persist through repeated annual burning.[7]
