Can be smooth or hairy and may have occasional hairs extending from margins of leaf blade. STEMS: Up to 30" tall, branched at base to give tufted appearance. FLOWERS: The spike (seed head) is cylindrical, more than 10 times as long as it is wide. 2 to 12 spikelets (joints) per spike, 1/2" long. Spikelets awned with uppermost spikelets having especially long awns. At maturity spikelets separate and look like sheat stems. ROOTS: Shallow, fibrous. SEEDS: 1 to 3 per spikelet. OTHER: Reduces grain yields and can be a contaminant in winter wheat, reducing prices.
