Description
"Tufted, rhizomatous, perennial; culms branching, nodes and internodes glabrous. Leaves cauline; blades glabrous on both surfaces, margins scaberulous, bases cordate; sheaths conspicuously overlapping, glabrous, usually pilose apically; ligules membranous, ciliolate, less than 0.4 mm long; collars usually pilose. Spikes racemose; branches spreading, flexuous, angled, scaberulous. Spikelets in two rows on one side of rachis, 1-flwoered, occasionally a rudiment present in G. amibguus, appressed; pedicels angled, scaberulous, absent or to 1.5 mm long. Glumes 1-nerved, margins usually scarious; paleas 2-nerved, margins usually scarious, acute; callus usually bearded; rachilla prolonged or capped by sterile floret. Grain reddish, linear-ellipsoid." - Radford et al 1964
"Culms 3-6 dm tall. Blades frequently cuspidate, to 9 cm long. Spikelets usually length of spike, 4.5-6.5 cmm long. Glumes 3.5-6.5 mm long; fertile lemma usually glabrous, body 3.5-4 mm long, awn usually 5-10 mm long, occasionally a long, awned sterile lemmas present; paleas 3.5-4 mm long. Grain 2.5-2.6 mm long." - Radford et al 1964
Distribution
Ecology
Habitat
This species is found on longleaf pine sandhills, open wiregrass-pinewoods savannas, mesic pine flatwoods, palmetto-wiregrass-longleaf pine woodlands, pine barrens, and mixed woodlands (FSU Herbarium). They occur on dry and moist sandy loam in these environments as well as human disturbed habitats such as along back roads (FSU Herbarium). Associated species includes Aristida stricta, Muhlenbergia, Schizachyrium, Panicum anceps, Paspalum bifidum, Pinus palutris, Andropogon, Pinus elliottii, Lilium, Verbesina chapmanii, Platanthera integra, Carphephorus paniculatus, Sabal palmetto, Quercus falcata (FSU Herbarium).
Phenology
It has been observed to flower and fruit in January, April, September through October, and December (FSU Herbarium). It also flowers in August.[1]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [2]
Use by animals
Comprised deer diets more in the summer than in the winter.[3]
