This species is a rhizomatous or stoloniferous perennial grass growing in mounds with stems up to half a meter tall. The inflorescence is a panicle of flowers up to 10 centimeters long with upright or spreading branches. It flowers in March and April, the spikelets green with webby fibers.

Threats to this rare species include the invasion of non-native grasses, such as purple veldtgrass (Ehrharta calycina).[4]
