A terrestrial orchid 6-15 cm high, fleshy, brittle, yellowish-green or reddish. Inflorescence sparse, 1-3 cm long, 1-6-flowered. Flowers approximately 15 mm across, green and red or wholly reddish. Dorsal sepal approximately 3.5 mm long, 4 mm wide; lateral sepals linear to lanceolate, 9-10 mm long, approximately 1.5 mm wide, widely divergent. Petals approximately 3 mm long, 1.5 mm wide, striped.

The species has been recorded from locations between Ulladulla and Port Stephens. About half the records were made before 1960 with most of the older records being from Sydney suburbs including Asquith, Cowan, Gladesville, Longueville and Wahroonga. No collections have been made from those sites in recent years. Currently the species is known from just over 200 plants across 13 sites. The species has been recorded at locations now likely to be within the following conservation reserves: Berowra Valley Regional Park, Royal National Park and Lane Cove National Park. May occur in the Woronora, O’Hares, Metropolitan and Warragamba Catchments.
