Common Name The Different Sized Wings Masdevallia [refers to the dorsal and lateral speals different shapes]

Flower Size 2/4" [2 cm]

Found in Antioquia department of Colombia in cloud forests at elevations around 2500 to 2700 meters as a mini-miniature sized, cold growing epiphyte with erect, slender ramicauls enveloped basally by 2 to 3 loose, tubular sheaths and carrying a single, apical, erect, coriaceous, narrowly elliptic, subacute to obtuse leaf that is cuneate below into the petiole and blooms in the spring and fall on a loose, successively few flowered, 4 3/4" [12 cm] long inflorescence arising from low on the ramicaul with a bract above the base and tubular floral bracts

As it's name implies it has a major difference between the shape of the dorsal sepals and the lateral sepals. If they are of the same length and form then most likely your species is M fasciata. Often sited as a synonym of M fasciata but it is definitely a distinct species.

Synonyms Masdevallia fissa Kraenzl. 1921; Rodrigoa heteroptera (Rchb.f.) Braas 1979
