Cymbidium suave, commonly known as the snake orchid or grassy boat-lip orchid, is a plant in the orchid family and is endemic to eastern Australia. It is an epiphytic orchid that forms long-lasting clumps of grass-like leaves. Up to fifty crowded olive green to dark or brownish green flowers are borne on an arching flowering stem. Of the three Australian species of Cymbidium, this is the only one that does not have prominent pseudobulbs. It is found in eastern Australia, usually growing in the hollows of old or fallen, decaying trees.
Cymbidium canaliculatum, commonly known as the channelled boat-lip orchid, tiger boat-lip orchid, native cymbidium or tiger orchid is a plant in the orchid family and is endemic to Australia. It is a clump-forming epiphyte with large, greyish green pseudobulbs, each with up to six curved, deeply channelled leaves and up to sixty fragrant, variably coloured flowers that often have spots and blotches and a white to cream-coloured labellum with red markings. This orchid usually grows in the forks or hollows of trees and is found from New South Wales to the northern parts of Western Australia.
Pterostylis grandiflora, commonly known as the cobra greenhood or superb greenhood, is a species of orchid endemic to south-eastern Australia. As with similar orchids, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves but the flowering plants lack a rosette and have a single flower with leaves on the flowering spike. This greenhood has a green and white, striped flower with deep red-brown markings especially on its "galea", and a sharply pointed dorsal sepal.
Prostanthera ovalifolia, commonly known as the oval-leaf mintbush or purple mintbush, is a species of flowering plant in the family Lamiaceae and is endemic to south-eastern continental Australia. It is an erect shrub with egg-shaped leaves and groups of mauve to deep blue-purple flowers arranged in groups at the ends of branchlets.
Lyperanthus, commonly known as beak orchids, is a genus of flowering plants from the orchid family, Orchidaceae, that is endemic to Australia. There are two species, one in Western Australia and the other in four eastern Australian states, distinguished by their single long, narrow, leathery leaf and dull coloured flowers which have prominent short calli on their labellum. Both form loose colonies which reproduce asexually from their tubers, and sexually using their flowers.
Orthoceras strictum, commonly known as the bird's-mouth orchid or horned orchid, is a species of orchid native to eastern and southern Australia, New Zealand and New Caledonia. It has between two and five linear leaves and up to nine yellowish green, brownish or blackish flowers with two long, erect to spreading lateral sepals.
Genoplesium fimbriatum, commonly known as the fringed midge orchid is a small terrestrial orchid found from southern Queensland to southern New South Wales. It has a single thin leaf and up to thirty green to brownish-green flowers with red stripes and a red-tipped labellum with hairy edges.
Lyperanthus suaveolens, commonly called brown beaks, is a species of orchid that is endemic to the eastern states of Australia.
Prasophyllum alpinum, commonly known as the alpine leek orchid, is a species of orchid endemic to Tasmania. It was formerly described as occurring in mainland Australia but has smaller flowers than the species occurring there. It has a single, tube-shaped leaf and up to fourteen green to greenish-brown flowers and grows in subalpine areas.
Pterostylis cucullata, commonly known as the leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. It has a rosette of fleshy leaves at its base and a single white, green and reddish-brown flower.
Pterostylis squamata, commonly known as the southern rustyhood or ruddyhood, is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. Flowering plants have up to ten translucent green flowers with reddish-brown markings and a hairy, insect-like labellum. Non-flowering plants have a rosette of four to eight egg-shaped leaves. This species is very similar to Pterostylis rufa which has a narrower labellum and other minor differences.
Pterostylis gibbosa, commonly known as the Illawarra rustyhood, or Illawarra greenhood, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It has a rosette of leaves at its base and up to nine bright green flowers with translucent "windows", relatively wide lateral sepals with short-pointed tips and a dark, fleshy, insect-like labellum.
Pterostylis ophioglossa, commonly known as the snake-tongue greenhood, is a species of orchid endemic to eastern Australia. It has a rosette of leaves at the base and a single dull green, white and brown flower with a deeply notched labellum.
Pterostylis reflexa, commonly known as the dainty greenhood, is a species of orchid endemic to New South Wales. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering stem. This greenhood has a relatively large white, green and light brown flower with a long, curved dorsal sepal and a protruding labellum.
Pyrorchis nigricans, commonly known as red beaks, is a species of orchid endemic to Australia and is found in all Australian states except Queensland and the Northern Territory. It has a single large, oval leaf and up to eight relatively large red and white flowers. It usually only flowers after hot fires.
Acianthus caudatus, commonly known as the mayfly orchid, is a flowering plant in the orchid family Orchidaceae and is endemic to eastern Australia. It is a terrestrial herb with a single egg-shaped or heart-shaped leaf and up to nine dark purplish flowers with thin, spreading sepals and petals, often with a musty odour.

Thelymitra media, commonly called the tall sun orchid, is a species of orchid that is endemic to eastern Australia. It has a single fleshy, channelled leaf and up to thirty blue flowers with darker streaks but without spots. The labellum is narrower than the other petals and sepals.
Dendrobium canaliculatum, commonly known as the brown tea tree orchid or thin tea tree orchid, is an epiphytic or lithophytic orchid in the family Orchidaceae. It has cone-shaped or onion-shaped pseudobulbs, up to six deeply channelled, dark green leaves and up to thirty star-shaped, light brown to caramel-coloured white or greenish to apricot-coloured flowers with darker tips. It grows in tropical North Queensland and New Guinea.
Dendrobium rigidum, commonly known as the smooth tongue orchid or smooth tick orchid, is a species of orchid native to tropical North Queensland and to New Guinea.
