Found in Costa Rica, Panama and Colombia as a miniature sized, hot to warm growing epiphytic herb at elevations of around 1000 meters with close set, ovoid, smooth pseudobulbs carrying a single, apical, erect, coriaceous, elliptic, obtuse, basally clasping leaf that blooms in the spring and is different in that it has a basal, erect, lateral, 2" [5 cm] long, simultaneously 2 to 6 flowered, inflorescence with prominent, slightly longer than the ovary, widely triangular-ovate, subacute, amplexicaul, margin crenulate floral bracts and carrying fragrant, resupinate flowers occuring in the winter.

Known by its stems that form fusiform pseudobulbs, the sinlge apical leaf, the lateral inflorescence arising from the base of the stem, that is shoreter than the leaf, carrying 5 to 10, green flowers with the sepals .4 to .48" [1 to 1.2 cm] long, and a trilobed lip with long calli.
