Plants cespitose or stoloniferous. Culms to 100 cm, often decumbent
or stoloniferous, freely branching; nodes bearded. Leaves mostly
basal, green, sometimes glaucous; sheaths glabrous, keeled; ligules
0.7-1.5 mm; blades 3-15 cm long, 3-4 mm wide, flat, margins and ligule
regions hairy. Panicles 3-5 cm, fan-shaped, often purplish; rachises
0.2-2 cm, with 3-8 branches; branches 3-4.5 cm, longer than the rachises,
usually with 1 rame; rame internodes with villous margins, with 1-3 mm
hairs. Sessile spikelets 3-4 mm, lanceolate; callus hairs about
1 mm; lower glumes sparsely hirtellous, with a prominent dorsal pit near
the middle; awns 10-17 mm; anthers 1-1.8 mm, yellow. Pedicellate

Bothriochloa pertusa is native to the Eastern Hemisphere, and was introduced
to the southern United States as a warm-season pasture grass. It now grows in
disturbed, moist, grassy places and pastures in the region, at elevations of
2-200 m. It has not persisted at all locations shown on the map.
