Morphology

Culm
Erect or rarely decumbent, glabrous.
Blades
Flat, 4-16 inches long, 1/4 to 1/2 inch wide, glabrous or pubescent, conspicuous "W" constriction on blades; margins rough.
Sheath
Round, prominently veined, glabrous or soft-hairy, waxy.
Ligule
Membranous, minutely jagged.
Inflorescence
Panicles, erect, 4-9 inches long, open or contracted, lowest branches whorled, terminal.
Spikelets
Approximately 1 inch long, less than 1/4 inch wide, pointed, often drooping, 4-10-flowered; glumes unequal, papery, first glume 1-nerved, second glume usually 3-nerved; lemmas greenish to purplish, mostly without awns, longer than glumes.

Ecology

Habitat
Roadsides, pastures, hayfields, waterways, ditches, and waste areas, more abundant in highly fertile sandy loam or clay loam soils.
Distribution
Throughout Kansas.

Practical Information

Forage Value
Smooth brome is highly nutritious and palatable to livestock. It makes excellent hay and forage.

Additional Notes

Comments

Strongly rhizomatous. Smooth brome is widely planted for pasture grazing, hay, wildlife cover, and to prevent soil erosion. It frequently escapes into other habitats. The prominent W-shaped constriction on the leaf blades readily distinguishes smooth brome.
