Synonym: Eragrostis virginica (Zuccagni) Steudel
Description
Weakley states that some authors have taken up the older name E. virginica, as a synonym for E. refracta, but the application of synonymy is uncertain[1].
Generally, for the Eragrostis genus, they are "annuals or perennials from short rhizomes or hardened bases. Glumes similar, shorter than lowest lemma. Florets more than 2. Lemmas 3-nerved, paleas persistent, ciliate" - Radford et al 1964.
Specifically, for Eragrostis refracta species, they are "cespitose perennial from hardened base; culms 3-10 dm tall, nodes and internodes glabrous. Leaves primarily low cauline; blades elongate, to 2.5 dm long, 1.5-4 mm wide, pilose above, glabrous beneath, margins scaberulous; sheaths glabrous; ligules membranous, 0.1-0.2 mm long, long trichomes in throat. Panicle loose, open ½-3/4 height of the plant, ½ to as broad as long; branches flexuous, scaberulous. Spikelets with dark margins and light centers, 4-22 flowered, lateral spikelets longer than pedicels, appressed, 8-13 mm long, 1.5-1.8 mm wide. Glumes 1-nerved, scabrous keeled, acuminate, 1st glume 0,8-1.3 mm long, 2nd glume 1.5-2 mm long; lemmas scabrous keeled, acuminate, 1.5-1.8 mm long; paleas 1-1.5 mm long. Grain reddish, oblong, 0.5-0.7 mm long." - Radford et al 1964.
Distribution
It is distributed from Deleware south to Florida, and west to Texas (Weakley 2015).
Ecology
Habitat
Is found in open longleaf pine woods, open woodlands[2] and in pineland, savannas, bogs and seeds, and marshes[1]. Is also found along the roadside edges. Requires high light levels. Is associated with areas with dry sand or dry, loamy sand soil types[2].
Associated species include Composites, legumes, and grasses. Also Eriocaulon lineare and Lachnocaulon minus[2].
Phenology
Has been observed flowering and fruiting from September to November[2].
