Densely tufted small perennial with short rhizome. Culms filiform, 0.5–4 cm high. Leaves longer than culms, blade to 6 cm long. Spikelets 1–3, ± hidden amongst leaves, 3–7 mm long; involucral bract to 3(–8) cm long, often as long as culm; glumes acute, not or scarcely mucronate, with the keel prominently thickened distally, sides faintly and irregularly several-nerved, whitish to straw-coloured, often flecked red-brown, 1.5–2.4 mm long; stamens 2 or 3 in lowermost flowers of a spikelet, 1 in upper; anthers 0.5–1 mm long; style 3-fid. Nut unequally trigonous, obovoid or ellipsoid, with angles not well-defined, minutely reticulate, shining, straw-coloured to grey-brown, from one-half to two-thirds as long as glume, 0.9–1.3 mm long, 0.5–0.8 mm diam. Flowers summer.

Isolepis montivaga is recognised by the well-developed leaf blades, the involucral bracts which are usually very long relative to the culm, spikelet size and smooth nuts.
