Leaves glabrous; blade 1–10 cm long and 1–4 mm wide, often inrolled when young, rigid, often sharp-pointed; ligule minute, but usually with longer (to 2 mm) hairs at the sides. Inflorescence a spike-like raceme mostly 1.5–4 cm long.

Zoysia tenuifolia Willd. ex Trin. (Mascarene Grass) was collected from farmland south of Sale in 1978. Although growing vigorously at the site, it has not been collected since and does not appear to have become naturalised in Victoria. It is readily distinguishable from Z. macrantha by the longer, rather weak and very fine foliage (less than 1 mm diam.). It is occasionally used as a coastal lawn grass or stabilizer of sand in northern Australia.
