Found in Costa Rica and Panama in wet montane cloud forests at elevations of 1300 to 1850 meters as a miniature sized, to cool growing epiphyte with a short rhizome giving rise to ovate pseudobulbs enveloped basally by 2 to 5, leaf-bearing sheaths with hyaline, scarious margins and carrying, rugose, laterally compressed, linear-lanceolate, subfalcate, acute leaves, the basal ones articulate to the sheaths that blooms in the summer on a lateral, peduncle filiform, provided with 2 triangular, acute bracts, lax, 3.45" [8.6 cm] long, 11 to 17 flowered inflorescence with a single, triangular, acuminate, shorter than the ovary floral bract.
