Acacallis (orchid)

For the mythological Greek mortal after whom this genus is named, see Acacallis (mythology). Acacallis Lindl. 1853, was a small South American genus with a few species from the orchid family Orchidaceae.According to the authoritative database of the Royal Botanical Gardens in Kew, the genus Acacallis Lindl. has become a synonym of Aganisia Lindl. All Acacallis species have now been synonymized with Aganisia species, except Acacallis rosariana V.P.Castro & M.M.Silva that has become an unplaced name.The species of this former genus are found in the countries of Brazil, Colombia, Venezuela, Guyana, and Peru. Both species have flowers that generally reach 4cm in width and whose color is rare among orchids, varying from a rose-tinted violet to a blue-tinted violet produced from a creeping rhizome.
