Common Name The Rose-Like Masdevallia

Flower Size 1" [2.5 cm] wide

Found in Peru without locational data as a mini-miniature to miniature sized, caespitose epiphyte with slender, erect ramicauls enveloped by 2 to 3, tubular sheaths and carrying an erect, coriaceous, elliptical, acute, cuneate below into the petiolate base leaf that blooms in the fall on a slender, erect, peduncle 2.4 to 3.2" [6 to 8 cm] long, single flowered inflorescence with somewhat shorter to just as long as the pedicel floral bracts and carrying flowers with white sepals faintly suffused with rose below the middle, white petals and a yellow white lip with purplish at the apex.

"Both vegetatively and florally, this species is superficially similar to Masdevallia amoena of SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Oscillantes Luer 1986 , but the simple lip of M. rosacea indicates SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Caudatae Veitch 1889 . Masdevallia rosacea also differs with glabrous, white sepals lightly suffused with rose below the middle and a concave dorsal sepal. The sepals of M. amoena are light rose, suffused with yellow toward the base, and the dorsal sepal is not concave. The lip of M. rosacea differs by being oblong and more or less flat and featureless, while the lip of M. amoena is more or less winged with a slight constriction below the recurved tip. " Luer 2012
