Arachnis annamensis is a species of orchid, originated in Vietnam. [1]
It is a sizable monopodial orchid that thrives in warm climates, exhibiting epiphytic growth. The elongated stem carries numerous alternate leaves, slightly bilobed at the apex. It produces an upright inflorescence around 60 cm long in spring, with numerous flowers in the axils. [1]
It is found in Vietnam in evergreen, semi-deciduous forests, and low dry deciduous forests at elevations from sea level to 1500 meters.
Arachnis annamensis was described by (Rolfe) J.J.Sm. and published in Dutch-Indian Journal of Natural History 72: 73. 1912. [2]
Arachnis: generic name derived from the Latinization of the word Greek: αράχνη (arachnis) meaning "spider", about the shape of its flowers.
annamensis: Geographical epithet referring to its location in Annam in Vietnam. [1]
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.
Vanda, abbreviated in the horticultural trade as V., is a genus in the orchid family, Orchidaceae. There are 90 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.
Alstonia is a widespread genus of evergreen trees and shrubs, of the family Apocynaceae. It was named by Robert Brown in 1811, after Charles Alston (1685–1760), professor of botany at Edinburgh from 1716 to 1760.
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.

Many areas of Vietnam are under protection. While the national reserves cover small areas of scientific significance with restricted access, the national parks also cover wetlands of Ramsar designated areas and BirdLife International inscribed bird areas. The largest of the national parks initially covered were the Cúc Phương National Park, the Cát Tiên National Park, and the Côn Đảo National Park which to start with were forest areas cum reserves or prohibited areas. The objective for creating national parks was to allow access to the reserved areas as a part of ecotourism and cultural needs with full attention to the basic approach of conservation of natural environmental resources.
Triphora trianthophoros, the threebirds or three birds orchid, or nodding pogonia, is a species of terrestrial orchid native to eastern North America.
