Common Name Bonpland's Masdevallia [French Botanist in South America 1800's]

Flower Size 1" [2.5 cm]

Found in Colombia, Ecuador and Peru in cloud forests on fully exposed grassy hillsides at elevations of 1100 to 3750 meters as a small sized, cool to cold growing terrestrial orchid with stout, erect ramicauls carrying a single, apical, suberect to erect, thickly coriaceous, obovate-linear to semi-terete obutse, sulcate, leaf that is gradually narrowed into the subpetiolate base and blooms in the summer on a stout, suberect to erect, single flowered, 4" [10 cm] long, purple spotted, inflorescence that arises from low on the ramicaul with a bract near the base and a single floral bract. Very similar to M coriacea it differs in having a wider range, a smaller plant with narrower, semi-terete, sulcate leaves, a shorter peduncle and smaller flowers, except the lip and petals are almost the same in size and shape. The sepals are marked with purple either in heavy spots or various degrees of suffusin.
