Oldfield threeawn

Aristida oligantha



Grows in tufts and is branched at the base and nodes (freely branched above the base with age). The base is woolly. Leaf sheaths are smooth and rounded on the back. The open panicle has long, spreading awns of about equal length (2 to 3 1/2 inches). The lemma is also long. First and second glume persist after seed disperses.

Annual, warm-season, native - 12 to 24 inches tall.

Poor grazing for both livestock and wildlife.


Grows in upland areas and increases on disturbed and overgrazed areas. Plant density is controlled by the amount of bare ground and by the amount of rainfall in spring and early summer.
