Piptochaetium montevidense

Description

The leaves consist of a sheath, which partially encloses the stem, and a spreading leaf blade. They are tufted together at the base of the plant and alternately arranged along the stems. The leaf sheaths can be hairless (i.e. glabrous) to somewhat hairy (i.e. puberulous or pubescent) and where the leaf sheath meets the leaf blade there is a tiny membranous structure (i.e. membranous ligule) 0.5-2 mm long. The leaf blades (5-15 cm long and 0.5-1 mm wide) are extremely narrow (i.e. filiform) and are usually folded (i.e. conduplicate) or rolled inwards (i.e. involute or convolute). They have entire margins and hairless (i.e. glabrous) or somewhat hairy (i.e. pubescent) surfaces.
