Common Name The Quinata Sobralia [A tree in Costa Rica]
Found in Costa Rica on the Atlantic slope at elevations of 1000 to 1400 meters as a small to just medium sized, warm growing terrestrial with stems that are sometimes leafless and carrying from 0 to 4, plicate, elliptic, long-acuminate, acute leaves that blooms in the summer and fall on a terminal, curved, 1.5" [3.5 cm] long, successively single flowered inflorescence arising from an imbricate, ellipsoid bract cluster.
Similar to S Sobralia fuzukiae but differs in the flower being faced backward facing the stem so as to hide the lip, 3 prominent keels that are tallest at or near the apice and have some erect lobules, as well as a inflorescence that is markedly curved and 1" or longer with the flowers arising from the outer edges.
