Found in Holguin province of eastern Cuba in humid and shady to open conditions, along waterways or foggy mountain crests in gallery forests or montane rainforests from 300 to 800 meters as a mini-miniature sized, hot to warm growing, shortly repent epiphyte or lithophyte with an erect ramicaul enveloped completely by 2 scarious, infundibuliform, conduplite, acute sheaths and carrying a single, apical, erect, coriaceous, obovate to spathulate to broadly elliptic, flat to folded, grey green to green above, green beneath, obtuse to acute to subacumiante, tridentate, narrow to shortly attenuate below into the base leaf that blooms in the spring on a pendent to erect, 1.2 to 2.8" [3 to 7 cm] long, 2 to few flowered inflorescence with tubular, as long as the pedicel floral bract.

"Characterized by a row of narrowly linear leaves produced by ramicauls about 06" [1.5 mm] long. The flower seemed to have been solitary but later proved to be successively flowered. The dorsal sepal and synsepal barely separate and the petals are proprtionally large. The lip is ovoid with the apical half narrowly obtuse and papillose. Below the middle the sides are thick and erect behind short, antrorse lateral lobes. Immediately above the base is a circular structure, concave anteriorly and elevated with a curved callus at the base. The base is solidly connate to the base of the column. The anther is eight loculate with eight free, pyriform pollina." Luer 2006
