Pterostylis is a genus of about 300 species of plants in the orchid family, Orchidaceae. Commonly called greenhood orchids, they are terrestrial, deciduous, perennial, tuberous, herbs found in Australia, New Zealand, New Guinea, New Caledonia and one Indonesian island. The flowers are mostly green, sometimes with brown, reddish or white stripes, and are distinguished from other orchids by their unusual flower structures and pollination mechanism.
Diuris, commonly known as donkey orchids, bee orchids, nanny goat orchids or pansy orchids, is a genus of more than sixty species of flowering plants in the orchid family, Orchidaceae and is endemic to Australia, apart from one species endemic to Timor. The name "Diuris" refers to the hanging sepals but the common name "donkey orchid", derives from the ear-like petals common to all species. Many have mainly yellow flowers with darker markings and are thought to mimic nectar-producing flowers which open at the same time.
Microtis, commonly known as onion orchids or mignonette orchids is a genus of about 20 species of plants in the orchid family, Orchidaceae. Onion orchids are terrestrial herbs with a single leaf at the base of the plant. They are similar to orchids in the genus Prasophyllum in that they have an onion-like leaf. The flowers are small but often scented and attractive to their insect pollinators. They are widespread in Asia, Australia and some Pacific islands.
Chiloglottis, commonly known as wasp orchids, ant orchids or bird orchids, is a genus of about 25 species of flowering plants in the orchid family, Orchidaceae and is found in eastern Australia and New Zealand. Wasp orchids are terrestrial herbs which grow in colonies of genetically identical plants. They usually have two leaves at the base of the plant and a single resupinate ("upside-down") flower. The labellum is more or less diamond-shaped and has calli resembling the body of a wingless female wasp.
Eriochilus, commonly known as bunny orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is endemic to Australia. Orchids in this genus are distinguished from those in the similar Caladenia by having a glabrous leaf and a densely woolly labellum. Species occur in south-west Western Australia, South Australia, Queensland, New South Wales, the Australian Capital Territory, Victoria, and Tasmania. Their common name alludes to their prominent ear-like lateral sepals.
Corunastylis is a historically recognized genus of about 50 species of orchids, native to Australia and New Zealand, now included in the genera Genoplesium and Prasophyllum.
Cyanicula, commonly known as blue orchids, is a genus of twelve species of plants in the orchid family, Orchidaceae. All are endemic to Australia, eleven are endemic to Western Australia and one species occurs in eastern Australia. While both the common and scientific names refer to "blue", the two subspecies of C. ixioides have yellow or white flowers. They are similar to orchids in the genus Caladenia but differ in their flowers colour and in other important ways.
Genoplesium commonly known as midge orchids, is a genus of about 50 species of flowering plants in the orchid family, Orchidaceae and is found in Australia, New Zealand and New Caledonia. Midge orchids are terrestrial herbs with a single leaf at the base of the plant. They are similar to orchids in the genus Prasophyllum in that plants without flowers have a hollow, onion-like leaf. The flowers are small but often scented and attractive to their insect pollinators. There is disagreement about which species belong to this genus and some taxonomists suggest that most belong in the genus Corunastylis.

Caladenia longicauda subsp. merrittii, commonly known as Merritt's white spider orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and up to three large, mainly white flowers with very long, drooping lateral sepals and petals, and a white broad labellum with relatively short labellum teeth. It is one of the largest spider orchids.
Caladenia longicauda subsp. redacta, commonly known as the tangled white spider orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and up to three large, mainly white flowers with long, drooping lateral sepals and petals. It is most similar to subspecies eminems but has smaller flowers and shorter teeth on the side of the labellum.
Caladenia longicauda subsp. rigidula, commonly known as the rigid white spider orchid or island white spider orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and up to three large, mainly white flowers with relatively short lateral sepals and petals. It is similar to the reclining white spider orchid but that species has smaller, cream-coloured flowers.
Caladenia longicauda subsp. extrema, commonly known as the late white spider orchid or Seaton Ross spider orchid is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and one or two mainly white flowers with long, mostly spreading lateral sepals and petals. It is a relatively rare orchid which is similar to the tangled white spider orchid but has larger flowers and a later flowering period.
Caladenia exilis is a species of flowering plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It is a ground orchid with a single erect, linear leaf and up to three white to greenish-cream or dark pinkish-maroon flowers.
