Flower Size .8" [2 cm] wide

Found in La Paz department of Bolivia at elevations around 1500 meters as a miniature sized, cool growing, caespitose epiphyte with slender, erect ramicauls enveloped by 2 to 3, thin, tubular sheaths and carrying a single, apical, erect, coriaceous, narrowly obovate, subacute to obtuse, gradually narrowing below into the indistinct, petiolate base leaf that blooms in the winter on a suberect, slender, triquetrous peduncle, 3.2 to 4" [8 to 10 cm] long, from low on the ramicaul, rachis .8 to 1.2" [2 to 3 cm] long, loose, successively single, few flowered inflorescence with tubular shorter than the pedicel floral bracts and carrying flowers with glabrous sepals with the dorsal dull yellow, the laterals dull yellow, heavily suffused with brown, the petals white with purple dots on the apical margin and a diffusely spotted with purple lip.

"The species is closely related to M sanctae-fidei from Colombia and Venezuela but the species differs in the larger habit, the longer peduncle, the lax raceme, and the flowers less widely expanded synsepal. Other details of the sepals, petals and lip are very similar." Luer 2000
