Chiloglottis valida, commonly known as the large bird orchid[2] or common bird orchid,[3] is a species of orchid endemic to south-eastern Australia.It has two dark green leaves and a single greenish purple to purplish brown flower with six to ten blackish, column-like calli on the labellum.

There is a large, black, column-like callus up to 4 mm (0.2 in) long, surrounded by between one and four pairs of smaller calli on the labellum.

[2][3][4][5] Chiloglottis valida was first formally described in 1991 by David Jones from a specimen collected in Namadgi National Park and the description was published in Australian Orchid Research.

[6] The specific epithet (valida) is a Latin word meaning "strong", "sound" or "powerful",[7] in reference to this species being the largest in the genus.

[4] The large bird orchid is widespread and common, growing in a range of habitats from coastal to subalpine areas.
