Common Name The Pointed-Petal Masdevallia

Flower Size about 1" [about 2.5 cm]

This miniature sized, warm to cold growing, epiphytic species is found in Costa Rica, Panama and Ecuador in cloud forests at an altitude of 700 to 2400 meters with short, erect, slender stems enveloped basallly by 2 to 3 thin, close, tubular sheaths carrying a single apical, elliptic-oblong, conduplicate, petiolate leaf that gradually narrows below to a subpetiolate base and blooms with 1 flower per 2 to 3" [5 to 7.5 cm] long, erect inflorescence that is usually shorter than the leaves and has waxy, long-lasting, bell shaped flowers occuring in the late winter and early spring.

This species is very similar and may be conspecific with to Masdevallia laucheana but occurs ar lower elevations, has shorter inflorescence and smaller flowers with sharper lines on the sepals.
