Description
"Erect rhizomatous perennials. Spikelets compressed, glumes similar, shorter than lowest lemma. Lemmas 3-nerved, nerves ciliate, reduced upward, chartaceous; paleas equaling lemmas. Articulation below florets." - Radford et al 1964
"Perennial from elongate, scaly rhizomes, 2.5-5 mm thick; culms 8-12 dm tall, nodes and internodes glabrous. Leaves cauline, to 3.5 dm log, 2-7 mm wide; upper blades glabrous on both surfaces, lower blades sparsely pilose on both surfaces basally, margins smooth scaberulous; upper sheaths glabrous, lower, pilose; ligules ciliolate, 0.5 mm long. Panicle 9-15 cm long, 1-4 cm broad; branches ascending, glabrous. Spikelets 4-5 flowered, 7-9 mm long, 2-3 mm broad. Glumes 1-nerved, chartaceous, glabrous, retuse, cuspidate; 1st glume 3.5-4.5 mm long, 2nd glume 4-5 mm long; lemmas retuse, cuspidate, longest 4-5 mm long. Grain yellowish, ellipsoid, 2-2.5 mm long." - Radford et al 1964
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, T. carolinianus has been found in open longleaf pine forests; loamy sand of open pinewoods sandhill; annually burned pinelands; longleaf pine-live oak forests; sandy loam of longleaf pine-deciduous scrub oak forests; mesic longleaf pine-oak-persimmon community; and open, mesic pine flatwoods (FSU Herbarium). It has also been found in disturbed habitats such as pastures and old fields. Associated species include Quercus margarettae, Q. incana, Q. falcata, Liatris gracilis, Liatris tenuifolius, Ceanothus americanus, Aristida beyrichiana, Pityopsis graminifolia var. tenuifolia, Schizachyrium tenerum, Eriogonum tomentosum, Licania michauxii, and Ctenium (FSU Herbarium).
Phenology
It flowers and fruits August through November (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [1] =
