Rosette leaves 6–15, narrowly elliptic, 10–20 x 6–8mm, greyish-green. Flower stem 30–5 long, 1.5– across, 1–6-flowered. Stem bracts 2–4. Flowers porrect, on long slender stalks (often downcurved) with sepal tips of lowest flowers often touching soil, 30–38 x 6–8mm, transparent with pale green or brownish markings (often boldly marked with dark brown in SA). Dorsal sepal point filamentous, 10–1 long, porrect to decurved. Lateral sepals wider than hood, shallowly concave, margins thickened, densely hairy; free points filamentous, 20–2 long, decurved to incurved, parallel, those on lowest flowers often touching ground. Petals with small basal flanges, 9–11 x 3–3.5mm. Labellum obovate, 4.5–5 x 2mm, thin-textured, green to brown, broadly channelled, tip upcurved; margins entire, with 16–20 spreading bristles c.0. long; two prominent bristles c.1. long projecting from near base; basal lobe thin, sloping backwards, with short hairs.
Widespread but disjunct and localised, mainly in small populations, growing among rocks, shrubs, grasses, tussocks and forbs in open forest with relatively sparse understorey, particularly forests dominated by ironbarks, box and yellow gum; also grassland, in freely draining stony loams and clay loams that bake hard in summer; also in crevices and patches of moss on low rocky outcrops over thin sandy soil.
