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."[1]
Specifically, Erianthus alopecuroides have "culms to 3 m tall. Blades to 7.5 dm long and 3 cm wide. Panicle whitish to tawny, 1.5-3 dm long, 5-12 cm broad; rachis long villous. Spikelets villous, 6-8 mm long, awns twisted, flat, 10-16 mm long; callus beard exceeding spikelet. Grain 2.5 mm long."[1]
Distribution
E. alopecuroides is generally distributed from New Jersey west to Indiana, Illinois, Missouri, and Oklahoma south to Florida and Texas.[2]
Ecology
Habitat
This species grows in roadsides, fields, and woodland borders.[2] In the Coastal Plain in Florida and Georgia, E. alopecuroides can be found in longleaf pine forests, annually burned pinelands, fallow quail food patches, frequently burned mature longleaf pine-wiregrass communities, bordering wild plum thickets, pine-oak-hickory woods, mixed hardwood forests, and mesic woodlands. It can also be found along roadsides, cutover pineland clayhills, and powerline corridors. Soils include sandy loam, clayey soil, and loamy sand.[3]
Phenology
This species generally flowers in October.[2] It has been observed to flower and fruit from September through November.[3]
Conservation and management
E. alopecuroides is listed as presumed extirpated by the Ohio Department of Natural Resources, Division of Natural Areas and Preserves.[4]
