Trachynia Link
Tufted or rhizomatous perennials, rarely annual. Leaf-blades flat and thin or stiff and convolute. Inflorescence a raceme, the pedicels 1-3 mm long. Spikelets 6-22-flowered; glumes 3-7-nerved; lemmas usually awned, rarely apiculate; palea a little shorter than the lemma, ciliolate on the keels, truncate.
A genus of about 17 species centred on the Mediterranean, extending into temperate Europe and Asia and tropical highlands of both hemispheres; 2 species occur in Pakistan.
A homogeneous genus whose species have very similar spikelets and are distinguished mainly by vegetative characters. The species themselves are rather variable, and tend to intergrade one with another.
