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]
"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." [1]
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 (FSU Herbarium). It has been recorded to grow in sandy loam and clay loam soils (FSU Herbarium; [2]). Associated species include shortleaf pine, red oak, post oak, mockernut hickory, and longleaf pine (FSU Herbarium).
Phenology
Flowering and fruiting have been observed June and September (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by explosion mechanisms or by ants. [3]
