Description

M. davisii is grown cool and blooms in the late spring with a single brilliant yellow flower, usually deep orange inside. The 6.5 to 9 cm flowers hold themselves high and appear successively on an erect, slender peduncle

Distribution

M. davisii is found in growing on rocky slopes in Peru at elevations of between 3000 and 3600 metres.

Culture

M. davisii can be grown in cool conditions in partial shade. It should be potted in fine bark with perlite

.... The other parts of the flower are yellowish, white and of the deepest splendid orange inside; so that it would appear to give a most welcome contrast in a group of the scarlet and vermillion and white Masdevallias. It was discovered by a, most probably new collector, Mr. W. Davis... I have a very good opinion of this collector, who was introduced to me by a set of new dried Orchids; so I thought it my duty to attach the name of such a promising collector to such a welcome Masdevallia."


M. davisii flowered for the first time in England in August 1874 and rapidly gained favour, becoming widely cultivated in Europe for many years, but it eventually disappeared from collections, joining the ranks of "lost" orchid species, before being re-introduced by David Wellisch of San Francisco in 1978 and by Berthold Wurstle of Spielberg, Germany in 1980.
