Description

"Perennials. Blades usually scaberulous on both surfaces and margins; sheath margins scarious, at least apically; ligules scarious, erose or erose-ciliate. Spikelets 1-flowered. Glumes equaling or shorter than lemmas, lemmas not indurate. Grain enclosed by lemma and palea at maturity." [1]

"Cespitose perennial; culms 5-12 dm tall, nodes and internodes glabrous. Leaves primarily basal; blades flat or involute, to 3 dm long, 103 mm wide; sheaths scaberulous; ligules 2-5 mm long. Panicle open, diffuse, delicate, 2-5 dm long, 1-2 dm broad; branches capillary, spreading, scaberulous. Spikelets usually purplish, lanceolate to narrowly ellipsoid, 4-5 mm long excluding awn; pedicels capillary, spreading, scaberulous. Glumes usually 1-nerved, usually scaberulous on midrib, scarious, 1st glume body 0.3-1.2 mm long, awn 0.3-1.2 mm long, 2nd glume body 1-1.5 mm long, awn 1-1.5 mm long; lemmas purplish, 3-nerved, scaberulous, body 3-4 mm long, awns 3-12 mm long; paleas purplish, faintly nerved, acuminate, 3-4 mm long. Grain purplish, narrowly ellipsoid, 2-2.4 mm long." [1]

Distribution

Ecology

Habitat

M. capillaris responds negatively to soil disturbance by agriculture in Southwest Georgia.[2] It also responds positively or not at all to soil disturbance by roller chopping in South Florida.[3]

Muhlenbergia capillaris var. trichopodes is frequent and abundant in the Clayhill Longleaf Woodlands and Lower Panhandle Savannas community types as described in Carr et al. (2010).[4]

Phenology

M. capillaris has been observed flowering in September and October.[5]

Seed dispersal

This species is thought to be dispersed by gravity. [6]
