Flowers widely spaced, 2–4 open at once, externally scabrous, 8–9.5 x 2.5mm, dark green and white, apex brown. Dorsal sepal about as long as petals, both scabrous. Synsepalum flat in side view, stepped in sharply at top; frontal opening shallowly notched. Free points linear-tapered, c. long, just exceeding top of hood. Labellum not visible in any position, narrowly elliptical, 3–3.5 x 1.5mm, red-brown and white, blunt.
Highly localised in few widely scattered localities from near the coast to hinterland ranges, often growing in cold sites such as frost hollows, gullies, exposed ridges and rock outcrops in shrubby forest in freely draining stony soil.
