There are about 85 species distributed from tropical and subtropical Asia to the north-western Pacific. Most species grow in rainforest.
Dendrobium tetragonum, commonly known as the tree spider orchid, is a variable species of epiphytic or lithophytic orchid endemic to eastern Australia. Tree spider orchids are unusual in having pendulous pseudobulbs that are thin and wiry near the base then expand into a fleshy, four-sided upper section before tapering at the tip. There are only a few thin but leathery leaves at the end of the pseudobulbs and up to five flowers on relatively short flowering stems. To allow for the variations in the species there are five subspecies and a variety, some with a unique common name.
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.
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.
Drymoanthus, commonly known as midget orchids is a genus of epiphytic orchids in the family Orchidaceae. Plants in this genus are relatively small and unbranched with thick roots, narrow crowded leaves and small scented green flowers with a white labellum. There are four species, found in Australia, New Zealand and New Caledonia.
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.
Thelasis, commonly known as fly orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are usually epiphytes, sometimes lithophytes or rarely terrestrials. Some species have pseudobulbs with up to three leaves, whilst others have several leaves in two ranks. A large number of small, white or greenish yellow flowers are borne on a thin, arching flowering stem. There are about thirty species, distributed from tropical and subtropical Asia to the southwest Pacific.
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.
Octarrhena, commonly known as grub orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are small, orchids with short stems, thin roots, short, thick, fleshy leaves arranged in two ranks and tiny flowers. The labellum is rigidly attached to the base of the column. There are about fifty species native to areas from Sri Lanka and Malesia to the Western Pacific.
Pomatocalpa, commonly known as bladder orchids, or 鹿角兰属 , is a genus of about twenty five species from the orchid family, Orchidaceae. Plants in this genus are epiphytes or lithophytes with thick, leathery leaves and a large number of small flowers with a three-lobed labellum. There are about twenty five species found from tropical and subtropical Asia to the south-west Pacific.
Sarcanthopsis, commonly known as goliath orchids, is a genus of six species of flowering plants from the orchid family, Orchidaceae. Plants in this genus are large epiphytes or lithophytes with long, thick, leathery stems, large, crowded leathery leaves and many yellowish flowers on a branched flowering stem. Orchids in this genus occur in New Guinea and islands of the south-west Pacific.
Schoenorchis, commonly known as flea orchids, or 匙唇兰属 in Chinese, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are small epiphytes with thin roots, thin leafy stems with leaves in two ranks and tiny fragrant, almost tube-shaped flowers with a prominently spurred labellum. There are about twenty five species found from tropical and subtropical Asia to the Western Pacific.
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.
Bogoria matutina, commonly known as the cupped freckle orchid, is an epiphytic orchid from the family Orchidaceae. It has thin, spreading roots, fibrous stems, between three and eight dark green, leathery leaves and up to fifty fragrant, short-lived, yellowish flowers with brown blotches and a white or yellowish labellum. It usually grows on rainforest trees and is found in tropical North Queensland, Australia.
Robiquetia gracilistipes, commonly known as the large pouched orchid, is an epiphytic or lithophytic orchid from the family Orchidaceae that forms large, hanging, straggly clumps. It has long, thick, roots, a single stem, many thick, leathery leaves and up to forty cream-coloured, pale green or brownish flowers with red spots and a three-lobed labellum. It grows on trees and rocks in rainforest, usually in bright light. It is found in Malesia including New Guinea, the Solomon Islands 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.
