Found in Queensland, New South Wales, Victoria, Tasmania and South Australia at elevations of sea level to 600 meters in coastal scrub, heathlands and forests as a miniature sized, cool to cold growing terrestrial orchid occuring in light to moderate shade and sandy soil in moist eucalypt forests with small tubers giving rise to a solitary, stalked, cordate, somewhat three-lobed, apiculate leaf with reticulation above and purpilish below which is held horizontal to the ground that blooms in the winter and spring on an erect, slender, glabrous, 6" [15 cm] long, few [1 to 9] flowered inflorescence with lanceolate, acuminate bracts and flowers that have an unpleasant odor, said to being akin to an unwashed dog.
