Common Name The Golden Frog Masdevallia [Refers to the yellow flower]

Flower Size 1.2" [3 cm]

Found in northwestern Peru without collection data as a mini-miniature sized, caespitose presumably epiphytic orchid with erect, slender, blackish ramicauls enveloped by 2 to 3 tubular sheaths and carrying a single, apical, erect, coriaceous, elliptical, acute, narrowly cuneate below into the blackish petiolate base leaf that blooms in the fall on a slender, arising from low on the ramicaul, suberect, [4 to 5 cm] long, single flowered inflorescence with a tubular, as long as the pedicel floral bract.

"Similar to M os-viperae but the leaves are elliptical, not narrowly ovate and acute. All floral parts of M rana-aurea are pure orange, the same color as seen in M hirtzii. The sepals are connate into a slightly compressed, narrowly cylindrical tube with the free portions broadly expanded, but totally glabrous as in M hirtzii. The petals, lip and column are similar to M os-viperae." Luer 1999
