Genus of orchids
Acanthophippium is a genus of orchid with thirteen species (family Orchidaceae). 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.
This terrestrial and sometimes myco-heterotrophic genus of sympodial orchids is distributed from the Indian subcontinent to Taiwan, China, Japan, Southeast Asia, New Guinea and the southwest Pacific.
The terrestrial species are up to 80 cm tall. They have short rhizomes. The oblong and fleshy pseudobulbs are up to 25 cm tall. They produce at their apex 2 to 3 large , , parallel-veined leaves, which can be up to 65 cm long.
The erect inflorescence arises laterally from the pseudobulbs, with 3 to 6 flowers, by large, bracts. The flowers are prominent, large, cup- or urn-shaped, fleshy, waxy, and about 4 cm long. They resemble a tulip, a most unusual shape for an orchid. The flowers have a wide range of colors, from dull yellow to red to shades of orange and pink, marked with stripes or spots. The blossoms are usually odiferous with a very strong fragrance.
This genus is allied to genera "Calanthe", "Cephalantheropsis", "Phaius", and "Spathoglottis".
Taxonomy.
The genus "Acanthophippium" was first described by Carl Ludwig Blume in 1825. He used the spelling with an "o". Many sources have since spelt the name "Acanthephippium" (i.e. with an "e"). This is regarded as an orthographic variant by the International Plant Names Index. The original spelling is used by sources such as the World Checklist of Selected Plant Families.
