Sporobolus airoides (Torr.).
Alkali Sacaton

Habit: 		Perennial, in large tough bunches.
Culms: 		50-100 cm. tall, erect to spreading, simple.
Blades: 	Elongate, flat, soon becoming involute, 5-35 cm. long, 1-3 mm. wide, sometimes
		sparingly hairy at the base, elsewhere somewhat rough.
Sheaths:	Shorter than the internodes, pilose at the throat.
Ligule: 	Very short.
Inflorescence: 	Panicle 10-40 cm. long, nearly half the height of the plant, when mature half
		to two thirds as wide as long, exserted or partly included, its branches and branchlets
		at length widely spreading, bearing spikelets aggregated along the outer half to two thirds.
Spikelets: 	1.5-2.5 mm. long, 1-flowered, awnless, on short pedicels, the lateral about as long
		as the spikelet rachilla disarticulating above the glumes.
Glumes: 	Acute, glabrous, nerveless, the first about half as long as the second, commonly
		falling towards maturity, the second about as long as the lemma.
Lemmas: 	Broadly oval, 1-nerved, about as long as the second glume.
Palea: 		2-nerved, about equaling the lemma, splitting between the strong nerves as the grain ripens.
Fruit: 		Grain free from the lemma and readily dropping off.
Habitat: 	Dry plains and river valleys, especially in alkaline soil.  August-September.
Kansas Range:	Southwest and Shawnee county.
Use: 		A good forage or grazing grass in lowland and in alkali regions.
