Found in Trinidad & Tobago, Venezuela, Guyana, Fr Guiana, Surinam and northern Brazil in rainforests at elevations of 100 to 1000 meters as a creeping, miniature sized, hot growing, long-repent epiphyte or lithophyte with stout, erect to suberect ramicauls enveloped by 2 thin, tubualr sheaths and carrying a single apical, erect, coriaceous, elliptical to broadly elliptical, otuse, cuneate below into the petiolate base leaf often purple below leaves that blooms on an erect, to arching, subflexuous, successively many flowered inflorescence with shorter than the pedicel floral bracts.

"The ascending ramicauls bear a slightly longer elliptical leaf with a successive, solitary flower at the base. The narrow dorsal sepal is conspicuously longer than the deeply concave synsepal. The petals are microscopically denticulate. The lip is elliptical, deeply denticulate above the middle with a serrated, lateral lobe below the middle and with a pair of crested calli on the middle third." Luer 2004
