It has many common names, including, the Toothed Habenaria, Dai-Sagi-So, Seitaka-sagi-s, Mao Yu Feng Hua, Wan khao nieo, and Ueang khao tok. [1]
The whole plant is about 35 to 80 cm in height. It has a smooth round tuber that give rise to a single plant. Lower part of stem sheathed, middle leafy and upper part bracteate. Leaves 4 to 6 cm long, oblong to elliptic, 5 nerved, sometimes 7 also, the base of the leaf narrowed into a long tubular sheath. Spike 4 to 8 cm long, laxly flowered. Sepals sub-equal, broadly ovate, acute, spreading, the lateral pair sub-erect. Petals narrowly oblong, sub-acute, curved inwards, shorter than the sepals. Lip as long as the sepals, variable in breadth, with large cuneate or rounded, fimbriate or crenate side lobes and a small oblong entire apical lobe. Spur infundibuliform at the base, slender laterally compressed, geniculate, sub-clavate below the knee, longer than the shortly stalked beaked ovary. Stigmas separated by the area in the centre by the orifice of the spur. [2] It generally blooms in August- September.

Bletilla, common name urn orchid, is a temperate, terrestrial genus of orchids containing five currently recognized species distributed through China, Japan, Taiwan, south to Vietnam, Thailand and Myanmar. The name is actually a diminutive of Bletia because of the resemblance between the two genera even though Bletia is a New World genus. The genera JimensiaRaf. and PolytomaLour. ex Gomes are generally included into Bletilla. This genus is abbreviated Ble in trade journals.
Calanthe, commonly known as Christmas orchids, is a genus of about 220 species of orchids in the family Orchidaceae. They are evergreen or deciduous terrestrial plants with thick roots, small oval pseudobulbs, large corrugated leaves and upright, sometimes arching flowering stems. The sepals and petals are narrow and a similar size to each other and the labellum usually has spreading lobes.
Phaius, commonly known as swamp orchids or in Chinese as 鶴頂蘭屬/鹤顶兰属 , is a genus of forty-five species of flowering plants in the orchid family, Orchidaceae. They are evergreen, terrestrial herbs which form clumps with crowded, sometimes stem-like pseudobulbs, large, pleated leaves and relatively large, often colourful flowers. Species in this genus are found in the tropical parts of Africa, Asia, Southeast Asia, New Guinea, Australia, and various islands of the Pacific and Indian Oceans. One species is also naturalized in Hawaii, Florida, and the Caribbean.
Zeuxine, commonly known as verdant jewel orchids, is a genus of about eighty species of orchids in the tribe Cranichideae. They are native to parts of tropical Africa, Asia, Southeast Asia, New Guinea, Australia and some Pacific Islands. They have relatively narrow, dark green leaves and small, dull-coloured resupinate flowers with the dorsal sepal and petals overlapping to form a hood over the column. The labellum has a pouched base and its tip has two lobes.
Goodyera, commonly called rattlesnake plantain, jade orchids or ladies' tresses is a wide-ranging genus of orchids in the tribe Cranichideae. About 100 species of Goodyera have been formally described. With a center of diversity in East Asia, Goodyera is found across Europe, Madeira, North and Central America, Australia, and on islands from the west Indian Ocean to the Pacific Ocean. They have a rosette of leaves at their base and usually many small white resupinate flowers. They are similar to orchids in the genus Spiranthes but can be distinguished from them by the shape and colour patterns of the leaves.
Platanthera blephariglottis, commonly known as the white fringed orchid or white-fringed orchis, is a species of orchid of the genus Platanthera. It is considered to be an endangered species in Connecticut and Ohio, a threatened species in Florida, Maryland and Rhode Island, exploitably vulnerable in New York, and susceptible to be threatened in Québec.
Gastrodia, commonly known as potato orchids or as 天麻属 , is a genus of terrestrial leafless orchids in the family Orchidaceae, about ninety of which have been described. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to Asia, Australia, New Zealand, central Africa, and various islands of the Indian and Pacific Oceans.

It contains about 100 species widespread across many of the tropical areas of the world.
Neottia is a genus of orchids. The genus now includes the former genus Listera, commonly known as twayblades referring to the single pair of opposite leaves at the base of the flowering stem. The genus is native to temperate, subarctic and arctic regions across most of Europe, northern Asia, and North America, with a few species extending into subtropical regions in the Mediterranean, Indochina, the southeastern United States, etc.
