Common Name The Slim-Beaked Masdevallia

Flower Size 1 1/2" [3.75 cm]

Endemic to Antioquia department of Colombia in cloud forests at elevations of 2000 to 2200 meters as a miniature sized, cold growing, caespitose epiphyte with stout, erect ramicauls enveloped by 2 to 3 loose, tubular sheaths carrying a single, apical, erect, coriaceous, elliptical-obovate, apically obtuse to rounded leaf that gradually narrows into the subpetiolate base that blooms in the spring on a stout, arising from the base of the ramicaul with a basal bract, congested, erect, 2 2.8" to 3.4" [7 to 8.5 cm] long, successively few flowered, racemose, triquetrous inflorescence with tubular, imbricating, shorter to as long as the pedicel floral bracts holding the successive single flower at leaf height.

"Recognized by the distinctive large flowers with a yellow green dorsal sepal and brown spotted, expanded lateral sepals with recurving margins. The lateral sepals are deeply connate, but they are connate to the dorsal sepal only at the base, forming a negligible sepaline cup. The tail of the dorsal sepal curves upward beyond the horizontal blade, while the acuminate tails of the lateral sepals bend downwards only slightly. The epichile of the lip is remarkably crested and fringed." Luer 2000
