Pterostylis stenochila, commonly known as the narrow-lip leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to Tasmania. Flowering plants have up to seven shiny, transparent green flowers with darker green stripes. The flowers have an insect-like labellum which is green with an emerald green stripe along its centre. Non-flowering plants have a rosette of leaves on a stalk, but flowering plants lack the rosette, instead having five or six stem leaves.
Arthrochilus, commonly called elbow orchids, is a genus of about fifteen species of flowering plants from the orchid family (Orchidaceae) and is found in Australia and New Guinea. The flowers are pollinated by male thynnid wasps which attempt to mate with the flower and are held in place by hooks while the pollinium is transferred between insect and flower.
Arthrochilus latipes, commonly known as robust elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to the "Top End" of the Northern Territory in Australia. Each plant has from two to four ground-hugging leaves and between three and fifteen flowers during the wet season and the species often forms spreading colonies on sandstone escarpments. Like others in the genus, the flowers are pollinated by a species of thynnid wasp.
Pterostylis williamsonii, commonly known as the brown-lip leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to Tasmania. Flowering plants have up to seven transparent green flowers with darker green and brown bands and a hairy, insect-like labellum with a blackish stripe. Non-flowering plants have a rosette of leaves on a short stalk but flowering plants lack the rosette, instead having five to seven stem leaves.
Pterostylis hamata, commonly known as the southern hooked rustyhood, is a plant in the orchid family Orchidaceae and is endemic to eastern Australia. It has a rosette of leaves and between two and twelve transparent flowers with green and brown markings, a thick, brown, insect-like labellum and dished lateral sepals.
Pterostylis calceolus, commonly known as the Bungonia rustyhood, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It has a rosette of overlapping leaves and between two and seven reddish-brown flowers with transparent "windows" and a fleshy brown, insect-like labellum. It is only known from near Bungonia.
Pterostylis flavovirens, commonly known as the coastal banded greenhood, is a plant in the orchid family Orchidaceae that is endemic to South Australia. As with other similar orchids, non-flowering plants differ from those in flower. Flowering plants have up to seven pale to translucent green flowers with darker green stripes. The flowers have an insect-like labellum which is yellowish green with a slightly darker green stripe along its centre. Non-flowering plants have a rosette of leaves on a stalk, but flowering plants lack the rosette, instead having three to six stem leaves.
Arthrochilus huntianus, commonly known as common elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to south-eastern Australia. It has no leaves but an insect-like flower which has its labellum dangling like a lure away from the rest of the flower. Because of its thin, wiry stem and small, dull-coloured flowers, this orchid is difficult to locate. Like others in the genus, the flowers are pollinated by a species of thynnid wasp. Some authorities use the name Thynninorchis huntiana for this orchid.

This species is known by some authorities as Phoringopsis byrnesii.
Arthrochilus corinnae, commonly known as the swamp elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to the northern part of Cape York in Queensland. It has two or three dull bluish green leaves near its base and up to twelve pale green, insect-like flowers with shiny yellowish glands on its labellum.
Arthrochilus dockrillii, commonly known as the green truffle orchid, is a species of flowering plant in the orchid family (Orchidaceae) and is endemic to Tropical North Queensland. It has one or two dark green leaves at its base and up to twenty five greenish, insect-like flowers with red glands on its labellum. This species is known by some authorities as Phoringopsis dockrillii. There is a single record of this species from Papua New Guinea.
Arthrochilus irritabilis, commonly known as clubbed elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to Queensland. It has up to five leaves and up to thirty light greenish or reddish, insect-like flower with reddish, hair-like glands on its labellum. There is a single record of this species from Papua New Guinea.
Arthrochilus laevicallus is a species of flowering plant in the orchid family (Orchidaceae) and is endemic to Papua New Guinea. It is leafless but has up to seven green, insect-like flowers with dark reddish glands on its labellum.
