Taxonomic notes
Synonym: Tragia linearifolia Elliott.[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]
"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."[2]
The root system of Tragia urens includes stem tubers which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion.[3] Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 137 mg/g (ranking 41 out of 100 species studied) and water content of 52.2% (ranking 20 out of 100 species studied).[3]
According to Diaz-Torbio and Putz (2021), Tragia urens has stem tubers with a below-ground to above-ground biomass ratio of 1.41 and nonstructural carbohydrate concentration of 137 mg g-1.[4]
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.[5] Associated species include longleaf pine, sand pine, and wiregrass.[5] T. urens has shown regrowth in reestablished South Carolina coastal plain communities that were disturbed by agriculture, making it a possible indicator species for post-agricultural woodlands.[6] However, in some areas of South Carolina it was unaffected by agricultural practices.[7]
Tragia urens is frequent and abundant in the Peninsula Xeric Sandhills and Panhandle Xeric Sandhills community types and is an indicator species for the North Florida Subxeric Sandhills community type as described in Carr et al. (2010).[8]
Phenology
T. urens has been observed flowering in April, May, and July and fruiting May through September.[9]
Seed dispersal
This species is thought to be dispersed by ants and/or explosive dehiscence.[10]
Fire ecology
Populations of Tragia urens have been known to persist through repeated annual burns.[11][12][13]
