This is a robust annual, 4 to 8 feet tall, with broad blades like those of corn or sorghum, and a dense, erect, cylindric spikelike panicle as much as a foot long, the stem woolly below the spike, the involucre containing usually two spikelets about as long as the bristles. Pearl millet dif- fers from the other Paniceae in having an enlarged cary- opsis bursting through its lemma and palea. The cary- opsis, or " seed," is deciduous by an articulation above the fertile lemma, the bristles and the floral bracts re- maining on the spike. Pearl millet is widely cultivated in tropical Africa and Asia, the seed being used for hu- man food. The species has been cultivated since pre-.
