Common Name The Three-Edged Masdevallia

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

Found in Colombia, Ecuador, Peru and Venezuela in mist forests at elevations of 750 to 2300 meters as a medium to small sized, mini-miniature sized, warm to cold growing, tufted epiphytic plant with a slender, erect, blackish ramicaul enveloped basally by 2 to 3 tubular sheaths carrying a single, apical, 6" [15 cm] long, obovate, erect or suberect, coriaceous, and their margins tend to furl toward the long petiolate base leaf that blooms in the summer and fall 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 and carrying a single fragrant, musty, repugnant smelling flower held well above the leaves.

This species likes an airy, humid, well watered environment.

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.
