Chiloglottis trapeziformis
Also called Dainty Bird Orchid, Diamond Ant Orchid
A small, deciduous, tuberous terrestrial orchid native to south-eastern Australia, with two narrow leaves and a single flower with a diamond-shaped lip. It is a wild woodland orchid rarely grown in gardens, and it depends on the presence of its ant pollinator and on sheltered, undisturbed sites.
Chiloglottis trapeziformis, commonly known as broad-lip bird orchid, diamond ant orchid or dainty bird-orchid, is a species of orchid endemic to south-eastern Australia. It has two narrow leaves and a narrow, greenish to purplish or brownish flower with a short, shiny black, ant-like callus covering the lower quarter of the diamond-shaped labellum. It has been recorded as a vagrant in New Zealand.
Broad-lip bird orchid is widespread and common in sheltered sites in a wide range of habitats. It occurs in south-eastern Queensland, eastern New South Wales and eastern Victoria. There is a single small population in south-eastern South Australia and scattered populations at Wynyard, Launceston, Flinders Island and Great Dog Island in Tasmania. A single vagrant population, now extinct, was known from a pine plantation near Levin in New Zealand.
