Alyxia is an Australasian genus of flowering plant in the dogbane family, Apocynaceae. It contains at present 106 species, but Alyxia stellata and A. tisserantii are very variable, might be cryptic species complexes, and are need of further study. It consists of shrubby, climbing or scrambling plants. This genus occurs in China, the Himalayas, Southeast Asia, Australia, New Caledonia and the Pacific Islands. There are 14 species in Australia, 21 in New Caledonia and 7 in the other Pacific Islands, including Hawaiʻi.
Gaultheria is a genus of about 283 species of shrubs in the family Ericaceae. The name commemorates Jean François Gaultier of Quebec, an honour bestowed by the Scandinavian Pehr Kalm in 1748 and taken up by Carl Linnaeus in his Species Plantarum. These plants are native to Asia, Australasia and North and South America. In the past, the Southern Hemisphere species were often treated as the separate genus Pernettya, but no consistent reliable morphological or genetic differences support recognition of two genera, and they are now united in the single genus Gaultheria.
Canarium is a genus of about 100 species of tropical and subtropical trees, in the family Burseraceae. They grow naturally across tropical Africa, south and southeast Asia, Indochina, Malesia, Australia and western Pacific Islands; including from southern Nigeria east to Madagascar, Mauritius, Sri Lanka and India; from Burma, Malaysia and Thailand through the Malay Peninsula and Vietnam to south China, Taiwan and the Philippines; through Borneo, Indonesia, Timor and New Guinea, through to the Solomon Islands, Vanuatu, New Caledonia, Fiji, Samoa, Tonga and Palau.
Plocoglottis is a genus of orchids, native to Southeast Asia and to various islands from the Andaman Islands to the Solomons.
Lecanorchis is a genus of orchids belonging to the subfamily Vanilloideae.
Chionanthus, common name: fringetrees, is a genus of about 150 species of flowering plants in the family Oleaceae.
Actinodaphne is an Asian genus of flowering plants in the laurel family (Lauraceae). It contains approximately 125 species of dioecious evergreen trees and shrubs.
Pothos is a genus of flowering plants in the family Araceae. It is native to China, the Indian Subcontinent, Australia, New Guinea, Southeast Asia, and various islands of the Pacific and Indian Oceans.
Cyrtostachys is a genus of flowering plant in the family Arecaceae. Its species are found in southeast Asia, New Guinea, and in some of the South-Central and Southwest Pacific island habitats of the Oceanian realm.
Ptychosperma is a genus of flowering plant in the family Arecaceae. Most are native to Australia and/or New Guinea, with a few in the Solomon Islands and in Maluku Province of eastern Indonesia. Some have been cultivated abroad as house or garden plants, and reportedly naturalized in certain regions.
Anodendron is a genus of plant in the family Apocynaceae first described as a genus in 1844. It is native to most of tropical Asia: China, the Indian subcontinent, Southeast Asia, New Guinea, and some islands of the western Pacific.
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.
Hydriastele is a diverse and widespread genus of flowering plant in the palm family found throughout northern Australia, Melanesia, Polynesia, and Southeast Asia. It consisted of just nine species until 2004, when molecular research, supported by morphologic similarities, led taxonomists to include the members of the Gulubia, Gronophyllum, and Siphokentia genera. About 40 species are now recognized.
Pholidota, commonly known as rattlesnake orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are clump-forming epiphytes or lithophytes with pseudobulbs, each with a single large leaf and a large number of small, whitish flowers arranged in two ranks along a thin, wiry flowering stem that emerges from the top of the pseudobulb. There are about thirty five species native to areas from tropical and subtropical Asia to the southwestern Pacific.
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.
Hetaeria, commonly known as hairy jewel orchids, is a genus of about thirty species of flowering plants in the orchid family Orchidaceae. Plants in this genus are terrestrial herbs with a succulent rhizome and a loose rosette of leaves. Small, pale, hairy non-resupinate flowers are borne on a thin, hairy flowering stem. They are found in tropical Africa and Asia to New Guinea, Australia and some Pacific Islands.
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.
Hornstedtia is a genus of plants in the Zingiberaceae. It is native to Southeast Asia, the Himalayas, southern China, New Guinea, Melanesia and Queensland.
