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.[3]

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 plicate, lanceolate, parallel-veined leaves, which can be up to 65 cm long.[4]

The erect inflorescence arises laterally from the pseudobulbs, with 3 to 6 flowers, subtended by large, glabrous bracts. The flowers are prominent, large, striated 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.[4]

This genus is allied to genera Calanthe, Cephalantheropsis, Phaius, and Spathoglottis.

Taxonomy

[edit]

The genus Acanthophippium was first described by Carl Ludwig Blume in 1825. He used the spelling with an "o".[5] 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.[6] The original spelling is used by sources such as the World Checklist of Selected Plant Families.[1]
