Chiloglottis diphylla, commonly known as the common wasp orchid, is a species of orchid endemic to Australia. It has two broad leaves and a single narrow, greenish brown to reddish flower with a black, insect-like callus covering the upper surface of the labellum.
Chiloglottis diphylla is a terrestrial, perennial, deciduous, herb with two leaves NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. A single greenish brown to reddish flower NaNsigfig=1NaNsigfig=1 long and NaNsigfig=2NaNsigfig=2 wide is borne on a flowering stem NaNsigfig=1NaNsigfig=1 high. The dorsal sepal is spatula-shaped, NaNsigfig=1NaNsigfig=1 long and about 2sigfig=1NaNsigfig=1 wide with a glandular tip a further NaNsigfig=1NaNsigfig=1 long. The lateral sepals are NaNsigfig=1NaNsigfig=1 long, about 0.5sigfig=1NaNsigfig=1 wide and curve downwards. There is a glandular tip NaNsigfig=1NaNsigfig=1 long on the end of each lateral sepal. The petals are oblong, NaNsigfig=1NaNsigfig=1 long, about 2sigfig=1NaNsigfig=1 wide and turned strongly downwards. The labellum is diamond-shaped, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=2NaNsigfig=2 wide with a black, insect-like callus covering most of its upper surface. Flowering occurs from February to May.[1] [2]
Chiloglottis diphylla was first formally described in 1810 by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[3] [4]
The common wasp orchid grows in moist places in shrubby forest on the coast and ranges between Carnarvon Gorge in Queensland and Batemans Bay in New South Wales.
