Description
Erianthus are "coarse perennials from hardened bases or short rhizomes; culms usually purplish, nodes usually, glabrous or upper appressed pubescent, internodes usually glabrous. Leaves primarily cauline; blades scaberulous, usually densely long hirsute above ligule; sheaths usually glabrous; ligules membranous, ciliate, 1-4 mm long; collars long-hirsute. Panicle solitary, terminal, ovoid to ellipsoid. Racemes numerous, most ascending, joints and pedicels subequal, 2-6 mm long, scaberulous or villous. Spikelets in pairs, fertile, sessile and pedicellate, yellowish to purplish, ovoid. Glumes cartilaginous, acuminate, subequal; lemmas and paleas hyaline to purplish, shorter than glumes; callus usually bearded. Grain reddish, ellipsoid, 2-3.5 mm long." - Radford et al 1964.
Specifically, for this species, they grow "culms 1-1.5 m tall. Blades to 4 dm long and 1 cm wide. Panicle tawny or purplish, 3-3.5 dm long, usually 3-5 cm broad; rachis villous. Raceme nearly erect, appressed. Spikelets usually scaberulous, 6-9 mm long, awns terete, scaberulous, nearly straight, 2-3 cm long; callus beard slightly shorter than to equaling spikelet. Grain 3 mm long." - Radford et al 1964.
Distribution
It is found in the lowland areas of old growth longleaf pine sandhill community at the Wade Tract, Thomas County, Georgia.
Ecology
Habitat
In the Coastal Plain in Florida, E. coarctatus can be found in mesic flatwoods, lake shores, pinewoods, sloughs, along canal banks, swales, hillside bogs, dried up ponds, and pine-oak woodlands (FSU Herbarium). It can also be found in roadside ditches and cleared pine flatwoods. Soil types include loamy sand and sandy peat (FSU Herbarium).
