Apostasioideae is one of the five subfamilies recognised within the orchid family, Orchidaceae. Only two genera, Neuwiedia and Apostasia, and 15 species, are recognised within the Apostasioideae in contrast to the other orchid subfamilies which are highly species rich.
Apostasia, commonly known as grass orchids, is a genus of eight species of primitive orchids in the family Orchidaceae. They are terrestrial, evergreen, grass-like plants, barely recognisable as orchids and are distributed in humid areas of the Himalayan region, China, India, Sri Lanka, Southeast Asia, New Guinea, and Queensland. They have many narrow leaves and small yellow or white, non-resupinate, star-like flowers usually arranged on a branched flowering stem.
Tainia, commonly known as ribbon orchids or 带唇兰属 is a genus of about thirty species of evergreen, terrestrial orchids in the distributed from India, China, Japan, Southeast Asia to New Guinea, the Solomon Islands and Queensland.
Odontochilus is a small genus from the orchid family (Orchidaceae). These terrestrial, mycoparasitic orchids occur from China, Japan, the Himalayas, Southeast Asia, New Guinea and Melanesia. The genus is related to Gonatostylis, endemic to New Caledonia.
Phoebe is a genus of evergreen trees and shrubs belonging to the Laurel family, Lauraceae. There are 75 accepted species in the genus, distributed in tropical and subtropical Asia and New Guinea. 35 species occur in China, of which 27 are endemic. The first description of the genus was of the type species P. lanceolata made in 1836 by Christian Gottfried Daniel Nees von Esenbeck in Systema Laurinarum, p. 98.
Acriopsis, commonly known as chandelier orchids or 合萼兰属 is a genus of flowering plants in the family Orchidaceaes. Orchids in this genus are epiphytic herbs with spherical or cylindrical pseudobulbs, creeping, branched rhizomes, thin white roots, two or three leaves and many small flowers. The flowers are non-resupinate with the lateral sepals joined along their edges and have spreading petals and a three-lobed labellum. The column has projections that extend hood-like beyond the anther.
Rhynchostylis is a genus in the orchid family (Orchidaceae), closely allied to the genus Vanda and comprising four currently accepted species native to the Indian Subcontinent, China, Indochina, Malaysia, Indonesia and the Philippines. The name consists of a compound of two Greek elements : rhynchos 'beak' and stylis 'column' – in reference to the very broad, fleshy column of the flower. The flowers are borne in dense racemes and are noted for their intense, spicy fragrance. Although lacking in pseudobulbs, the plants have leathery leaves that are drought-resistant. These orchids grow naturally in warm, moist, shaded tropical areas and will thrive in cultivation if given consistent warmth, uniform moisture and bright, but indirect light. Hobbyists wanting to grow them will need a warm, humid growing environment with gentle air movement. They can be grown in pots, but are better grown in baskets, owing to the extreme fleshiness of their roots. Their unusually fragrant blooms often appear in the slightly cooler winter months.
Trichoglottis, commonly known as cherub orchids or 毛舌兰属 , is a genus of flowering plants in the family Orchidaceae. Orchids in this genus are epiphytic plants with thick roots, relatively thick, fibrous stems and many large, thick, leathery leaves arranged in two ranks. The flowers are usually small and yellowish with light brown or purple markings. The flowers have broad sepals, narrower petals and a labellum which has three lobes and is often hairy. There are about 85 species distributed from tropical and subtropical Asia to the north-western Pacific. Most species grow in rainforest.
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.
Neuwiedia zollingeri is a species of orchid that native to Hainan, Hong Kong, Yunnan, Borneo, Sumatra, Java, Bali, Malaysia, Singapore, Thailand, Vietnam.
Brachypeza, commonly known as sage orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Orchids in this genus have short stems with fleshy leaves and arching flowering stems with short-lived flowers. The sepals and petals are similar in size and shape and the labellum is pouch-like and suspended at the base of the flower. Sage orchids occur in tropical areas from Indochina to New Guinea.
Chrysoglossum is a genus of flowering plants from the orchid family, Orchidaceae. Its 4 species are native to China, the Indian Subcontinent, southeast Asia, New Guinea and some islands of the western Pacific.
