Stems 4-10 dm. tall, rather stout, from a little longer than to twice as long as the basal leaves, the branches much divided, the lower ones usually elongate and nearly equaling the upper, thus forming a corymbiform panicle, the upper nodes of the primary and all those of the other branches densely barbed; leaf -sheaths keeled, those at the base much compressed and equitant, rough, often more or less papillose-hirsute, especially the shorter and crowded ones of the inflorescence; stem-leaves with blades 3 dm. long or less, 5 mm. wide or less, rough; spathes very rough, narrow and tightly rolled around the rather stout common peduncle of the racemes, which is densely hispidulous toward the summit, or loose and enclosing the racemes; racemes in pairs, 2-3 cm. long; sessile spikelet 4-5 mm. long, the awn 12-15 mm.
long, straight or nearly so; pedicellate spikelet usually present as a subulate scale 1-2 mm. long.

Andropogon glomeratus: Brief Summary

由wikipedia EN提供
Andropogon glomeratus is a species of grass known by the common names bushy bluestem and bushy beardgrass. This bunchgrass is native to the Americas, where it is widespread. It has also naturalized in other areas.
The genus name Andropogon comes from the Greek words 'aner' or 'andros' meaning "man" and 'pogon' meaning "beard", in reference to the hairs on the spikelets of certain species in this genus. The specific epithet glomeratus means "bunched", in reference to the species' bushy and broom-like inflorescences.
