Flower Size 1.2" [3 cm]

Found in Ecuador without collection data as a mini-miniature sized, cool growing, caespitose epiphyte with blackish, erect, slender ramicauls enveloped basally by 2 to 3 loose, tubular sheaths and carrying a single, apical, erect, coriaceous, elliptical, acute, narrowly cuneate below into the blackish, elongate petiolate base leaf that blooms in the summer on a slender, ascending to horizontal, 1.6 to 2.4" [4 to 6 cm] long, single flowered inflorescence arising from low on the ramicaul and a tubular floral bract.

"The superficially similar Masdevallia rosacea of the SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Caudatae Veitch 1889 differs from M amoena by the 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
