Common Name The Clawed Tongue Masdevallia [refers to the claw at the apex of the lip]

Flower Size 1.2" [3 cm] wide

Found in Peru without locational data as a small sized, caespitose, 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 8" [20 cm] long, provided with a basal bract, arising from low on the ramicaul, successively few, single flowered inflorescence with a tubular, shorter than the ovary floral bract.

"Superficially this species appears very similar to the Colombian Masdevallia tsubotae Luer. The only apparent differences are the petals and lip. Instead of merely oblong, the petals of M. cheloglossa are wide at the base with obtuse, marginal angles, and the epichile of the lip of M. cheloglossa is tubular with revolute sides, and with a prominent hook-like process at the tip."
