Description

It has a monopodial growth habit. The leaves are remarkable, as they are unusually purple for a Vanda. The purple foliage permits this plant to grow in full sun, as the accumulation of anthocyanins near the plant surface filters light and improves photoprotection. [3] This feature is also strongly expressed in hybrids. The flowers are rose or purple to white and are produced on 2-4 relatively short, densely many-flowered inflorescences. [2]

Taxonomy

This species is closely related to Vanda malipoensis and Vanda nana . The phylogenetic tree based on the plastid genome (i.e. the maternal line) indicates, that it is separate from other section Ascocentrum species. Section Ascocentrum is shown to be in part paraphyletic, depending on which genetic material is examined. The nuclear genome results in different relationships. This inconsistency can be explained by hybrid speciation. [4] This phylogenetic tree and the placement of Vanda christensoniana close to section Ascocentropsis, instead of section Ascocentrum, is confirmed in a second study. [5]

Orchidaceae Orchid family of flowering plants in the order Asparagales

Orchidaceae, commonly called the orchid family, is a diverse and widespread family of flowering plants, with blooms that are often colourful and fragrant.

<i>Vanda</i> Genus of orchids

Vanda, abbreviated in the horticultural trade as V., is a genus in the orchid family, Orchidaceae. There are about 87 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers. Vanda species are widespread across East Asia, Southeast Asia, and New Guinea, with a few species extending into Queensland and some of the islands of the western Pacific.

<i>Aerides</i> Genus of orchids

Aerides, known commonly as cat's-tail orchids and fox brush orchids, is a genus belonging to the orchid family. It is a group of tropical epiphyte orchids that grow mainly in the warm lowlands of tropical Asia from India to southern China to New Guinea. They are valued in horticulture for their racemes of showy, fragrant, colorful flowers.

<i>Phalaenopsis</i> Genus of orchids

Phalaenopsis, also known as moth orchids, is a genus of about seventy species of plants in the family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines.

<i>Cymbidium</i> Genus of flowering plants in the orchid family Orchidaceae

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.

Paulowniaceae Family of trees

Paulowniaceae are a family of flowering plants within the Lamiales. They are a monophyletic and monogeneric family of trees with currently 7 confirmed species. They were formerly placed within Scrophulariaceae sensu lato, or as a segregate of the Bignoniaceae.

<i>Holcoglossum</i> Genus of orchids

Holcoglossum (Holc.) is a genus of orchids, in the family Orchidaceae. It is native to China and Southeast Asia.

<i>Rhynchostylis</i> Genus of orchids

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.

Neofinetia Genus of flowering plants

Neofinetia was a genus of flowering plants from the orchid family, Orchidaceae, that is now classified as a Vanda. It contained three species and was distributed in China, Korea, and Japan.

<i>Vanda garayi</i> Species of orchid

Vanda garayi, or Garay's ascocentrum, is a small monopodial epiphytic orchid native to semi-deciduous and deciduous dry lowland forests of Thailand, Laos, and Sumatra.

<i>Vanda xichangensis</i> Species of epiphytic orchid

Vanda xichangensis is a species of epiphytic orchid native to China South-Central. It differs in the spur length from Vanda falcata. Some authors dispute this species status and regard it as a subspecies of Vanda falcata. Dr. Martin Motes argues against effective isolating mechanisms of the length of the spur. Accorting to Motes, the variation of this characteristic easily falls within a species range of variation and further research might reduce it to a varietal status.

<i>Phalaenopsis subparishii</i> Species of epiphytic orchid

Phalaenopsis subparishii, also known as 短茎萼脊兰 in Chinese, is a species of epiphyte in the family Orchidaceae, endemic to China, occurring in the provinces N Fujian, N Guangdong, NE Guizhou, SW Hubei, Hunan, NE Sichuan and Zhejiang at altitudes of 300–1100 m. The 1 to 1.5 cm long stems bear 1–10 cm long and 2.4-3.3 cm wide, alternate leaves. Inflorescences are between 9 and 10 cm in length and bear flowers with yellowish green, spotted petals and sepals. The spotting is pale brown on the adaxial surface. The midlobe bears lavender spotting. The horn-shaped spur ranges from 0.9 to 1.1 cm in length. The plants have four pollinia in two pairs. The species is closely related to Phalaenopsis tsii, which is however smaller than Phalaenopsis subparishii and it has a larger, white labellum in addition to a longer spur and column.

<i>Phalaenopsis japonica</i> Species of epiphytic orchid

Phalaenopsis japonica, also known as 萼脊兰 in Chinese, 나도붕난 (nadopungnan) in Korean and ナゴラン or 名護蘭 (nago-ran) in Japanese, is a species of epiphyte in the family Orchidaceae, native to open forests of China, Japan and Korea, occurring at altitudes of 600–1400 m. It also may grow lithophytically on cliffs along valleys. The 1 to 1.5 cm long stems bear 6–13 cm long and 2–3 cm wide, alternate leaves. Inflorescences are between 17 and 19 cm in length and bear flowers with whitish green, petals and sepals. The lateral sepals bear 1-3 transverse bands of dull brown spots on the adaxial surface. The midlobe is spotted purple to red. The horn-shaped spur ranges from 1.2 to 1.4 cm in length. The plants have four pollinia in two pairs, but previously they have been mistaken as two pollinia.

<i>Phalaenopsis hygrochila</i> Species of epiphytic orchid
