Common Name The Three-Edged Masdevallia

Flower Size to almost 5" [to almost 17.5 cm]

A mini-miniature sized, Colombian, Ecuadorian, Peruvian or Venezuelan, warm to cold growing, tufted epiphytic species found in mist forests at elevations of 750 to 2300 meters that likes an airy, humid, well watered environment, with which it will bloom in the summer and fall with a single non-fragrant flower held well above the leaves on an erect, slender, erect, to 6" [15 cm] long inflorescence arising from low on the ramicaul with a brown spotted bract near the base and a tubular floral bract. The medium to small sized plant has a slender, erect, blackish ramicaul enveloped basally by 2 to 3 tubular sheaths carrying a single, apical, 6" [15 cm] stalked leaves that are obovate, erect or suberect, coriaceous, and their margins tend to furl toward the base.

This species can be confused with M. instar but differs in having an obovate labellum lamina, of which the widest portion is just below the apical lobule which has a denticulate-tuberculate margin and surface.
