Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
Cymbidium, commonly known as boat orchids, is a genus of evergreen flowering plants in the orchid family Orchidaceae. Orchids in this genus are epiphytic, lithophytic, terrestrial or rarely leafless saprophytic herbs usually with pseudobulbs. There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The sepals and petals are all free from and similar to each other. The labellum is significantly different from the other petals and the sepals and has three lobes. There are about fifty-five species and sixteen further natural hybrids occurring in the wild from tropical and subtropical Asia to Australia. Cymbidiums are well known in horticulture and many cultivars have been developed. The genome of Cymbidium mannii has been sequenced to study epiphytism and crassulacean acid metabolism.
Cattleya is a genus of orchids from Costa Rica south to Argentina. The genus is abbreviated C in trade journals.
Acanthophippium is a genus of orchid with thirteen species. The name of this genus is derived from the Greek words acanthos ("spiny") and ephippion ("saddle"), referring to the saddle-like labellum of the plants.

Epipactis helleborine, the broad-leaved helleborine, is a terrestrial species of orchid with a broad distribution. It is a long lived herb which varies morphologically with ability to self-pollinate.
The genus Arachnis, abbreviated as Arach in horticultural trade, is a member of the orchid family (Orchidaceae), consisting of more than 20 species native to China, India, Southeast Asia, Indonesia, the Philippines, New Guinea, and the Solomon Islands.
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.
Scaphyglottis is a genus of orchids native to Mexico, Central America, northern South America and parts of the Caribbean. The current concept of this genus is the result of combining several genera which have been described at various times. The concept is characterized by the growth habit: not only are new pseudobulbs added at the base of the old ones, but new pseudobulbs also grow at the apices of the old ones. Many species are quite similar and difficult to distinguish, but some are clearly distinct. A few have showy colors. The genus comprises nearly 70 species.
Epidendrum conopseum, synonym Epidendrum magnoliae, sometimes called the green-fly orchid, is a species of orchid in the genus Epidendrum.
Cypripedium macranthos, the large-flowered cypripedium, is a species of orchid. It is native to Russia and East Asia.
Dactylorhiza sambucina, the elder-flowered orchid, is an herbaceous plant belonging to the family Orchidaceae. It is quite common and widespread throughout much of Europe from Portugal east to Finland and Ukraine. The flowers appear in spring and summer, in various colors from yellow to purple.
Dendrobium falconeri, commonly known as 串珠石斛 , is a species of orchid native to Asia.
Phalaenopsis taenialis, also known as 小尖囊蝴蝶兰 in Chinese, is a species of epiphytic orchid occurring from the eastern Himalaya to China (Yunnan). The specific epithet taenialis is derived from the long, flattened roots, which resemble tapeworms. The specific epithet taenialis, from the Latin taenia, means ribbon or band.
Papilionanthe is a genus of flowering plants from the orchid family, Orchidaceae. It is native to Southeast Asia, southern China, and the Indian Subcontinent.
Goodyera yunnanensis is a species of orchid endemic to southern China. It has been reported only from the provinces of Yunnan and Sichuan, growing in forest scrub at elevations of 2,600–3,900 m (8,500–12,800 ft).
Malaxis seychellarum is a species of orchid endemic to the Seychelles Islands in the Indian Ocean. First described in 1902, it is now considered a vulnerable species.
Hemipilia cucullata is a species of flowering plant in the family Orchidaceae, native to temperate Eurasia from Poland to Japan, and also to the Himalayas. It is terrestrial, growing from tubers, to a height of up to 30 cm, with pinkish flowers arranged in a one-sided spike. It was placed in several different genera before being placed in its present genus.
