Common names: Early millet Spring milletgrass
Treatment appears in FNA Volume 24. Treatment on page 780.

Plants annual. Culms 10-70 (90) cm, erect, solitary or clumped, retrorsely scabridulous; nodes 2-3, glabrous, green to purple. Sheaths retrorsely scabrous; ligules 2.5-4.5 mm, obtuse to acute, occasionally lacerate; blades 1.7-8.2 cm long, 1.9-5 mm wide, scabrous over the veins, concentrated on the lower portion of the culms. Panicles 4-11.5 cm; branches 0.5-6 cm, straight, ascending to erect, antrorsely scabrous, spikelets confined to the distal 1/2. Glumes 2.5-3.2 mm, scabridulous, 3-veined, acuminate; lemmas 2-2.3 mm; anthers about 1.5 mm. 2n = 18.

Discussion

Native to Eurasia, Milium vernale was first detected in North America in 1987, when it was found infesting winter wheat and other crops in north-central Idaho (Callihan & Pavek 1988). The infested area has since increased.
