Description
Annual or perennial, tufted. Culms geniculate ascending or prostrate. Leaf sheaths with or without keeled conspicuous, margins hyaline or hairy. Ligules ciliolate membrane, ciliolate rim or a fringe of hairs. Leaf blades linear, margins scabrous, usually chartaceous. Inflorescence spiciform panicle, usually cylindrical; racemes very short or false spike. Spikelets 1–8 in cluster, subtended by involucre of bristles and spines, these free at base to forming a cup and burr-like, filiform, terete or flattened, spikelet dorsally compressed; sessile or pedicelled. Lower glume shorter than spikelet or absent. Florets 2. Lower floret male or sterile. Lower lemma variable. Upper floret bisexual. Lodicules present or absent.
A genus of approximately 107 pantropical species, seven species were introduced in Thailand and have become naturalised in the country (the taxonomic treatments and a key to the species excluding the species were introduced so as to be useful in Thailand, but were not found or recorded in their natural habitat).
