Pappophorum bicolor
Culms 30-80 (100) cm. Sheaths mostly glabrous, apices with a tuft of hairs on either side; ligules about 1 mm; blades 10-20 (30) cm long, 2-5 mm wide, flat to involute. Panicles 12-20 cm, narrow but usually with some slightly spreading branches, pink or purple-tinged. Spikelets with the lower 2 or 3 florets bisexual, distal 1-2 florets sterile. Glumes 3-4 mm, thin, glabrous, apices acute or minutely notched and mucronate; lemmas somewhat firm, usually faintly 7-veined, with 11-15 awns; lowest lemma bodies 3-4 mm, midveins and margins pubescent from the base to about midlength, awns about 1.5 times as long as the lemma bodies; paleas subequal to the lemma bodies or slightly longer. Caryopses about 2 mm. 2n = 100.
Discussion
Pappophorum bicolor grows in open valleys, road right of ways, and grassy plains in Texas and northern Mexico. A report for Arizona (Mearns 1175) was apparently due to mixed labels. There have been no subsequent reports of the species from the state.
