LATE EARLY

Common Name The Spade Like Tongue Masdevallia [refers to the shape of the lip]

Flower Size 1.2" [3 cm] wide

Found in Peru without locational data as a small sized, presumably epiphytic orchid with stout, erect ramicauls enveloped by a tubular sheath and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, elliptical, subacute, cuneate below into the petiolate base leaf that blooms in the late summer and early fall on an erect, peduncle triquetrous, to 2.4 to 2.8" " [6 to 7 cm] long, provided with a bract below the middle, arising from low on the ramicaul, subcongested, successively few, single flowered inflorescence with a tubular, shorter than the ovary floral bract.

"Among the numerous species of subgenus Polyantha section Alatieaules, this species is characterized by a long-petiolate leaf and a peduncle not longer. The flower resembles one of those related to the common Masdevallia bicolor Poepp. & Endl. with sepaline cup, concave synsepal, and relatively short tails. The lip, however, is distinguished by an obovate, spade shape with a pair of prominent, marginal folds near the apex of the lip is triangular and minutely subverrucose with the tip decurved.
