Common Name The Constricted Masdevallia [refers to the elongate compressed sepaline tube]

Flower Size 1 1/2" [4 cm]

This mini-miniature, caespitose epiphytic species is found in Ecuador and Peru in wet montane forests on old trees and is best grown in warm to cool conditions as they are found at elevations of 1200 to 1800 meters with short, inconspicuous ramicauls hidden by basal, tubular, overlapping bracts with a single, apical, erect, coriaceous, oblong-oblanceolate, tapered to the channeled base leaf with a tridentate apex and blooms with a slender, suberect, 3" [8 cm] long, longer than the leaves, single flowered inflorescence arising from low on the ramicaul with a bract above the base and a floral bract holding the flower just above the leaves and all occuring in the fall through winter. A major distinguishing factor in this specis is the floral tube that is constricted at the middle.

The First 2 photos by Jay Pfahl illustrate what is known best as M constricta with a wider opening to the sepaline tube. The 2 photos by Eric Hunt are more what has been considered M urosalpinx with a much more narrow opening to the sepaline tube.
