They typically have spreading stems with wide, flat leaf blades that lie on the ground with the tips ascending. The inflorescence is a panicle in which the spike-like branches are arranged in a digitate fashion. The spikelets are arranged in two rows on an angled or winged rachis. Each spikelet has two florets, only one of which is fertile. The first bracts at the base of the spikelets are either very minute or absent.
