Evergreen plants with 2–10 leaves in a crowded clump, on stalks 10–30 mm long, elliptical, ovate or lanceolate, 40–100 × 20–30 mm, bright green, smooth. Flower stem 150–250 mm long, arching or drooping, 6–15-flowered. Flowers forward-facing, 18–25 × 16–20 mm, green to yellowish green with reddish or brown markings. Floral segments slender, with drawn out points. Dorsal sepal broadly ovate-lanceolate, 23–27 × 5–6 mm, concave, margins strongly incurved, hooding column. Lateral sepals narrowly lanceolate, 23–27 × 3 mm, decurved in front of flower, not widely divergent. Petals linear, 16–19 × 2 mm, spreading or recurved. Labellum shortly stalked, elliptical, 10–12 × 7–8 mm, curved, white or green with red markings, 3-lobed; lateral lobes erect beside column, wavy; midlobe curved. Calli forming irregular ridges on short basal plate. Column strongly incurved, 5–6 × c. 2 mm, green with red markings.
Highly localised and disjunct; found growing in yellow clay in horizontal fissures and crevices of sandstone cliffs and large boulders that are wet with seepage for most of the year; the long tuberous roots penetrate detritus in fissures and each clump produces several leaves that hang out of the crevice; the wet habitat also supports mosses and ferns.
