Taxonomy and discovery
This species was initially described as Phragmipedium xerophyticum by Soto Arenas, Salazar & Hágsater in 1990, but transferred to its own genus by Albert & Chase in 1992, in part based on results from
Its name is derived from the country of origin Mexico and the Latin pes (“foot”), referring to the slipper-shaped
Mexipedium xerophyticum is known from a single location in Oaxaca, Mexico. Only seven plants were observed at the time of its discovery. Mexipedium was recently rediscovered in a nearby locality.[3] A small number of plants were removed for propagation in case plant hunters eradicated the wild stock. Plants are now available as propagules.
Description and habitat
This is a lithophytic orchid, growing on cliffs, shielded from the sun, at an elevation of 320 m (1,050 ft).[3] But it grows as well on rocks or in the detritus in crevasses. Its growth form is unusual in that it tends to spread by runners, offset from the parent plant by several centimeters. The silvery-green leaves are small, stiff and semi-erect. The tiny white-pink flowers show a shieldlike, pinkish staminode and a slipper-shaped lip. The curved petals are scythe-shaped. Inflorescences are multifloral and branched.
