Perennials or annuals of various habit ; nodes of stem glabrous or 
hairy ; ligules usually reduced to a ciliate rim, rarely a distinct 
membrane. Panicle mostly cylindric, spike-like, dense, with the solitary 
or clustered spikelets on very short branches which are more or less 
produced into bristles beyond the spikelets or divided into a one-sided 
bristly involucre at their base, or more or less open with elongate 
branches and more distant spikelets, often with or without subtending 
bristles in the same inflorescence ; bristles always persistent. Spikelets
