Plants similar to subsp. rigidulum, but more conspicuously purple-tinged throughout, especially the panicles. Ligules 0.3-1 mm, membranous; blades usually 5-12 mm wide, flat, mostly glabrous or scabridulous, bases about equal in width to the subtending sheaths. Panicles relatively narrow; branches few, stiffly ascending. Spikelets 2.4-3 mm long, usually less than 0.6 mm wide, conspicuously stipitate, purple, often falcate, subsecund along the branchlets. Upper florets stipitate, stipes to 0.4 mm, slender.
