Found in Costa Rica and Panama at elevations of 1300 to 1450 meters as a mini-miniature sized, cool growing epiphyte with erect, slender ramicauls enveloped by 2 to 3 thin, loose, imbricating sheaths and carrying an erect, coriaceous, narrowly obovate, subacute, narrowly cuneate below into the petiolate base leaf that blooms in the late winter and early spring on an erect, distichous, filiform, to 1.8" [4.5 cm] long overall, rachis .8 to 1" [2 to 2.5 cm] long, loose, distichous, 3 to 4 simutaneously opening, several flowered inflorescence with thin, shorter than the pedicel floral bracts.

"Distinguished by the little tuft of narrowly obovate leaves topped by a slender, several flowered racemes that produces 3 to 4 tiny flowers simultaneously.THe sepals and epetals are simple, each about .04" [1 mm] long, THe habit is reminiscent of P lancilabris, not Platystele oxyglossa .
