INFLORESCENCE: An open panicle with relatively long, spreading, spindly stalks supporting the many spikelets. Flowering by late spring into fall depending on rainfall.

LEAVES: Narrow blades about 10 cm long and often just a few mm wide with the edges lightly involute. Glands and hairs absent from leaves and sheaths.
