Description
"Pubescent annual or weak perennial herbs from tap roots, freely branched with opposite branches. Stems obscurely angled, usually stipitate-glandular, leafy. Leaves entire or toothed, rarely lobed, petiolate to essentially sessile. Inflorescence a panicle of paired, bracteate, helicoid cymes with a flower at the axis of each pair; bracts similar to the leaves, smaller. Calyx bilabiate, lower lip longer than the upper with 3 essentially equal teeth, upper with 2 similar teeth; corolla blue to violet, zygomorphic, 5-lobed, lowest lobe lip-like, 5-10 mm long, lateral triangular-ovate, 2-4 mm long, tube short. Stamens 4, ca. 2X as long as the corolla, curved between the lateral lobes and curled downward almost meeting the lip; stigma bilobed, style curled in same fashion as stamens. Mericarps brownish to olive or blackish, dull, obovoid." [1]
"Stems, at least the principle ones, uniformly retrorsely short-pubescent, with trichomes 0.1-0.2 mm long. Leaves elliptic-linear, 1.5-4 cm long, 1-5 mm wide, entire, tapered to short petioles or sessile. Mericarps obscurely reticulate, 1.6-1.8 mm long." [1]
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Alabama, T. setaceum can be found in upland pine-hardwood forests, pinewoods, turkey oak-longleaf pine barrens, sand ridges, longleaf pine/scrub oak/wiregrass ridges, sandhill oak scrubs, and wiregrass-longleaf pine communities. [2] It is a ruderal species and can be found in cleared pine forests, turkey oak sand ridge clearings, and roadsides. Soil types include loamy sand and loamy soil. [2] Associated species include Vaccinium stamineum, Warea, Agalinis, Liatris, and Dicerandra. [2]
Phenology
Flowers and fruits September through November. [2]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [3]
Use by animals
It seems to be a major plant food for bobwhites during the month of October. [4]
