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.
Caladenia carnea, commonly known as pink fingers, is a plant in the orchid family Orchidaceae and is endemic to eastern and south-eastern Australia, including Tasmania. It has a single thin, green leaf and one to five white or pink flowers with red stripes and two rows of yellow-tipped "calli" on their labellum.
Adenochilus, commonly known as gnome orchids is a genus of two species of flowering plants in the orchid family Orchidaceae, one endemic to New Zealand and the other to Australia. Both species have a long, horizontal, underground rhizome with a single leaf on the flowering stem and a single resupinate flower with its dorsal sepal forming a hood over the labellum and column.
Cyrtostylis reniformis, commonly known as common gnat-orchid, is a species of orchid endemic to eastern Australia. It usually has a single kidney-shaped leaf and a flowering spike with up to eight reddish flowers with a shelf-like labellum.
Caladenia alpina, commonly known as the mountain caladenia, is a species of plant in the orchid family Orchidaceae and is native to subalpine areas of south-eastern Australia and to New Zealand. It has a single fleshy leaf and a thin wiry flowering spike bearing two white flowers with red bars on the labellum. In New Zealand this orchid is sometimes known as Caladenia lyallii.
Acianthus sinclairii, commonly known as pixie cap or heart-leaf orchid, is a flowering plant in the orchid family Orchidaceae and is endemic to New Zealand. It is a terrestrial herb with a single, heart-shaped leaf and up to ten translucent green flowers, usually tinged maroon.
Pterostylis foliata, commonly known as the slender greenhood, is a species of orchid widespread in south-eastern Australia and New Zealand. Flowering plants have a rosette of three to six, dark green, crinkled leaves crowded around the flowering stem and a single dark green and brown flower with a deep V-shaped sinus between the lateral sepals.
Pterostylis micromega, commonly known as the swamp greenhood, is a species of greenhood orchid endemic to New Zealand. Both flowering and non-flowering plants have a rosette of leaves while flowering plants also have a single, relatively large whitish flower with a pointed dorsal sepal. The flower colour and pointed dorsal sepal are unique in New Zealand Pterostylis.
Pterostylis puberula, commonly known as the dwarf greenhood or snail greenhood is a species of orchid which is endemic to New Zealand. It has a rosette of pale yellowish, stalked leaves and a single silvery-white and green flower with relatively long, erect lateral sepals.
Prasophyllum colensoi is a species of orchid endemic to New Zealand where it is commonly known as the leek orchid. It has a single tubular, dark green leaf and up to twenty scented, yellowish-green to reddish-brown flowers. It is similar to P. hectori, the only other species of Prasophyllum found in New Zealand, but is distinguished from it by its smaller size, fewer flowers and different habitat.
Prasophyllum solstitium is a species of orchid endemic to the Northern Tablelands of New South Wales. It has a single tubular, bright green leaf and up to thirty five greenish-pink to purplish-red flowers crowded on the flowering stem. It grows in grassland on heavy basalt soil.
Genoplesium nudum, commonly known as the tiny midge orchid in Australia or the red midge orchid in New Zealand, is a small terrestrial orchid native to south-eastern Australia and New Zealand. It has a single thin leaf fused to the flowering stem and up to forty small, reddish-purple or green and red flowers. Australian and New Zealand authorities use the name Corunastylis nuda but Genoplesium nudum and Prasophyllum transversum are used by the World Checklist of Selected Plant Families.
Prasophyllum crassum is a species of orchid endemic to South Australia. It has a single tube-shaped leaf and up to fifteen greenish and pinkish-brown flowers with a whitish labellum. It is a recently described plant, previously included with P. fitzgeraldii, but distinguished from that species by its smaller number of smaller, less colourful flowers and different labellum shape. It grows in the south-east of the state and usually only appears after fire.
Genoplesium pumilum, commonly known as the green midge orchid in Australia, and the yellow gumland leek orchid in New Zealand is a small terrestrial orchid native to south-eastern Australia and New Zealand. It has a single thin leaf fused to the flowering stem and up to twenty five green to yellowish-green flowers which sometimes have red markings. Australian and New Zealand authorities use the name Corunastylis pumila.
Microtis rara, commonly known as the scented onion orchid, is a species of orchid endemic to Australia, with the exception of the Northern Territory. It has a single hollow, onion-like leaf and up to fifty small green or yellowish-green, scented flowers. It is similar to Microtis oblonga and some authorities regard the two as being one species.
Chiloglottis cornuta, commonly known as the green bird orchid, is a species of orchid found in south-eastern Australia and in New Zealand, including many of its offshore islands. It has two broad leaves and a single green or pinkish flower with six to eight rounded, flattened green, reddish or blackish calli on the labellum.
Cyrtostylis oblonga, commonly known as the winter orchid or gnat orchid, is a species of orchid endemic to New Zealand. It has a single rounded leaf and a flowering stem with up to four pink or pinkish green flowers with a flat, oblong labellum.
Cyrtostylis robusta, commonly known as large gnat-orchid or mosquito orchid, is a species of orchid endemic to southern Australia. It usually has a single more or less round leaf and a flowering spike with up to seven reddish flowers with a shelf-like labellum.
Adenochilus gracilis is a species of plant in the orchid family Orchidaceae and is endemic to New Zealand. It has a long, thin underground rhizome, a single leaf on the flowering stem and a single white flower with glandular hairs on the outside. Its labellum has red to maroon bars and a central band of yellow calli, but is almost obscured by the dorsal sepal.
Corybas oblongus is a species of terrestrial orchid endemic to New Zealand. It has a solitary oval-shaped leaf, often patterned with maroon, and a reddish-purple and white flower with a fimbriate labellum.
