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."[1]
"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."[1].
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. Grows in dry and moist sandy loam in these environments as well as human disturbed habitats such as along back roads[2]. 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[2].
Phenology
It has been observed to flower and fruit in January, April, September through October, and December[2]. It also flowers in August.[3]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [4]
Use by animals
Comprised deer diets more in the summer than in the winter.[5]
