Spathoglottis, commonly known as purple orchids or 苞舌兰属 is a genus of about fifty species of orchids in the family Orchidaceae. They are evergreen terrestrial herbs with crowded pseudobulbs, a small number of leaves and medium-sized resupinate flowers on an upright flowering stem.

Species of Spathoglottis are found from eastern and south-eastern Asia to Australia and some Pacific Islands.
Caladenia, commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state.

These orchids are found from tropical Asia to northern Australia.
Tropidia, commonly known as crown orchids, is a genus of about thirty species of evergreen terrestrial orchids in the family Orchidaceae. They have thin, wiry stems with two or more tough, pleated leaves with a flowering spike at the top of the stem, bearing crowded flowers. Species in this genus are distributed across the warmer parts of both the Eastern and Western Hemispheres.
Bromheadia, commonly known as reed orchids, is a genus of about 29 species of orchids in the family Orchidaceae. They are evergreen terrestrial and epiphytic plants with unbranched stems, the leaves arranged in two rows along the flowering stem. The flowers appear in succession near the end of the flowering stem with the sepals and petals free from each other. The labellum is like a landing platform and has three lobes. They are native to areas from tropical Asia to northern Australia.
Sarcochilus, commonly known as butterfly orchids or fairy bells is a genus of about twenty species of flowering plants in the orchid family, Orchidaceae. Most species are epiphytes but a few species only grow on rocks or in leaf litter. Orchids in this genus usually have short stems, leaves arranged in two rows and flowers arranged along unbranched flowering stems. Most species are endemic to Australia but some are found in New Guinea and New Caledonia.
Cheirostylis, commonly known as fleshy jewel orchids or velvet orchids, is a genus of about sixty species of flowering plants in the orchid family Orchidaceae. Plants in this genus are terrestrial herbs with a caterpillar-like rhizome and a loose rosette of leaves. Small, white, hairy flowers develop as the leaves wither. They are found in tropical Africa, southern Asia, Southeast Asia, Malesia, New Guinea and Australia.
Geodorum, commonly known as shepherds' crooks or 地宝兰属 , is a genus of eight species of flowering plants in the orchid family, Orchidaceae. They are deciduous, terrestrial herbs with underground pseudobulbs, broad, pleated leaves and small to medium-sized, tube-shaped or bell-shaped flowers on a flowering stem with a drooping end. Species in this genus are found in southern Japan, tropical Asia, Australia and islands of the southwest Pacific Ocean.
Vrydagzynea, commonly called tonsil orchids, is a genus of orchids in the tribe Cranichideae. About forty five species of Vrydagzynea have been formally described. They are native to India, Taiwan, Southeast Asia, Malesia, Melanesia and Polynesia. A single species in Australia is possibly extinct. They have thinly textured, stalked leaves and small, dull-coloured resupinate flowers with the dorsal sepal and petals overlapping to form a hood over the column.
Townsonia, commonly called myrtle beech orchids is a genus of two species of flowering plants from the orchid family, Orchidaceae. They form small clusters of plants with their tubers connected, each tuber with one or two leaves. The flowers are inconspicuous.
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.
Micropera, commonly known as dismal orchids or 小囊兰属 is a genus of about twenty species of flowering plants from the orchid family, Orchidaceae. Plants in this genus are large epiphytes with thick roots, long, fibrous stems, linear leaves and whitish or yellow, non-resupinate flowers. The sepals and petals are similar to each other and the labellum is shoe-shaped or sac-like and has three lobes. It is found from Tibet to tropical Asia and the western Pacific Ocean.
Rhomboda, commonly known as velvet jewel orchids, is a genus of about twenty species of flowering plants in the orchid family Orchidaceae. Plants in this genus are mostly terrestrial herbs with a fleshy, creeping rhizome and a loose rosette of green to maroon coloured leaves. Small resupinate or partly resupinate, dull coloured flowers are borne on a hairy flowering stem. The dorsal sepal and petals overlap and form a hood over the column and there is a deep pouch at the base of the labellum. They are found in tropical regions from northern India through Southeast Asia, China, Japan to Australia and some Pacific Islands.
Phaius amboinensis, commonly known as Arnhem Land swamp orchid, is a plant in the orchid family and is native to areas from Malesia through to New Guinea, Australia and islands in the Pacific Ocean. It is an evergreen, terrestrial herb with up to eight pleated leaves and up to twenty, relatively large white flowers with a yellow labellum. It grows in wet, shady forests.
Rhinerrhizopsis, commonly known as freckle orchids, is a genus of three species from the orchid family, Orchidaceae.

These orchids are found in the Bismarck Archipelago, the Solomon Islands, New Guinea and tropical North Queensland, Australia.
Trachoma, commonly known as spectral orchids, is a genus of flowering plants in the family Orchidaceae. Orchids in this genus are epiphytic plants with leafy stems, crowded, leathery leaves arranged in two ranks and a large number of relatively small, short-lived flowers that often open in successive clusters. The sepals and petals are free from and more or less similar to each other, except that the petals are often smaller. The labellum is rigidly fixed to the column and is more or less sac-shaped. There are about 17 species distributed from Assam to the Western Pacific Ocean. Most species grow in rainforests, often on emergent trees such as hoop pine.
