Cyrtostylis, commonly known as gnat orchids, is a genus of five or six species of flowering plants in the orchid family Orchidaceae and is native to Australia and New Zealand. Cyrtostylis orchids often form dense colonies of genetically identical plants. They have a single heart-shaped leaf and a thin flowering stem with pale coloured insect-like flowers. The lateral sepals and petals are similar in size and colour but the labellum is shelf-like and conspicuous with two prominent glands at its base.
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.
Spathoglottis paulinae, commonly known as the small purple orchid, is a plant in the orchid family and is native to New Guinea and Tropical North Queensland. It is an evergreen terrestrial orchid with crowded pseudobulbs, between four and seven large, pleated leaves and up to thirty mauve to purple flowers.
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 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.
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.
Arthrochilus oreophilus, commonly known as montane elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to higher places in far north Queensland. It has a rosette of leaves at its base and up to fifteen green, insect-like flowers with dark reddish brown glands on its labellum.
Arthrochilus oreophilus, commonly known as the untidy elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to near the tip of Cape York in Queensland. It has two or three leaves at its base and up to seven pale green, insect-like flowers with reddish glands on its labellum.
Arthrochilus aquilus, commonly known as the dark 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 up to five dark green leaves at its base and up to fifteen pale green, insect-like flowers with dark reddish black glands on its labellum.
Arthrochilus byrnesii, commonly known as the sandstone truffle orchid, is a rare species of flowering plant in the orchid family (Orchidaceae) and is endemic to the far north-west of Australia. It has three dark green leaves at its base and up to fifteen greenish, insect-like flowers with dark reddish black glands on its labellum. 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 lavarackianus, commonly known as the glaucous truffle orchid, is a species of flowering plant in the orchid family (Orchidaceae) and is endemic to the Torres Strait and Tropical North Queensland. It has one or two bluish green leaves at its base and up to fifteen greenish, insect-like flowers with red glands on its mushroom-like labellum. This species is known by some authorities as Phoringopsis lavarackiana.
Arthrochilus prolixus, commonly known as wispy elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to eastern Australia. It has a rosette of bluish green leaves at its base and up to twenty two pale green, insect-like flowers with dark reddish to purplish glands on its labellum.
Arthrochilus rosulatus, commonly known as rosetted elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to Tropical North Queensland. It has a rosette of bluish green leaves surrounding its base and up to fifteen pale green, insect-like flowers with dark red glands on its labellum.
Arthrochilus sabulosus, commonly known as the spotted elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to Tropical North Queensland and Horn Island. It has a rosette of dull green leaves on side growth at its base and up to fifteen pale green, insect-like flowers with reddish to brownish glands on its labellum.
Arthrochilus stenophyllus, commonly known as the narrow-leaved elbow orchid, is a flowering plant in the orchid family (Orchidaceae) and is endemic to Tropical North Queensland. It has a rosette of dull green leaves on side growth at its base and up to fifteen pale green, insect-like flowers with dark red to brownish glands on its labellum.
