Perennial grass with erect culms to 180 cm tall. Sheaths closed, often pubescent, auricles greatly reduced or absent. Inflorescences narrow panicles with 6 to 9-flowered, laterally-compressed spikelets. Panicle branches with 1-5 spikelets.

Seed sample from: 2008
Average measurement: 14.6 x 1.5 x 1.5
Measurement range: L: 13.5 – 16 W: 1.1 – 1.8 D: 1.2 - 2
Shape: Inner seed is about ½ the size of its husk, and brown.
Color:Seed husk tan, tending to be whiter toward hilium, and browner towards awn.
Surface:Hilium is somewhat glossy, while rest of husk is very hairy. Awn is brown and straight. Surface of seed longitudinally striate and glossy.
Latitudinal cross section: elliptical
Longitudinal cross section: elliptical
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
