Common Name The Small Flowered Platystele

Flower Size 1/8" [3 mm]

Found in Costa Rica and Panama at elevations of 1400 to 2000 meters as a miniature sized, cool growing epiphyte with erect, slender ramicauls enveloped basally by 2 to 3 thin, ribbed, imbricating sheaths and carrying a single, apical, erect, coriaceous, narrowly-elliptical-obovate, subacute, narrowly cuneate into the petiolate base leaf that blooms in the winter and early spring on a erect, slender, .8" [2 cm] long including the .4" [1 cm] long peduncle, distichous, flexuous, subdense, successively several to many flowered, racemose inflorescence with only 1 to 2 flowers open at any one time arising from low on the ramicaul, and has thin, shorer than the pedicel floral bracts.

"In spite of the extremely small flowers P microtantha is easily distinguished by the comparitively large, flat, triangular callis occupying most of the basal portion of the lip. The callus, however, is not as wide as the blade of the lip. The column streching over the callis is unusually elongate for the genus. A similar species is P schneideri with a broadoer callus of the lip, is widely distributed throughout Columbia.
