Diagnosis:
Height: 2-8 inches

Culms: Erect or decumbent, slender, solid, shorter on female plants than on male plants; nodes glabrous; internodes flattened.
Blades: Flat, 1 to 5 inches long, sparsely hairy.
Sheaths: Loose, glabrous except for a few marginal hairs near collars.
Ligules: Membranous, fringed with hairs
Inflorescences: Inflorescences of staminate plants panicles; branches 2-5, 1/4 to 1/2 inch long, flag-like; inflorescences of pistillate plants bur-like, 1-3, almost hidden among leaves.
Spikelets: Spikelets of staminate plants 6-12 per branch, arranged in 2 rows; florets 2 per spikelet; spikelets of pistillate plants 2-5; florets 1 per spikelet; second glume and lemma awned.

Flowering Period: May, June


Habitat: Dry prairies, open woodlands, roadsides, and partially disturbed areas.


Forage Value: Livestock readily graze buffalo grass, except during dry spells when it goes dormant. It can furnish good winter grazing. Buffalo grass protects itself from being overgrazed by producing its leaves very close to the ground.

Comments: Sod-forming, dioecious (male and female flowers occur on separate plants); stolons 2 to 24 inches long, creeping, rooting at nodes. The foliage turns reddish brown after frost.


Conservation status: Not threatened


Distribution: Broadly distributed in the middle United States.  Found throughout Kansas.  See http://plants.usda.gov/java/profile?symbol=BODA2&mapType=nativity&photoI...
