Found in the Constanza province of Dominican Republic in cloud forests at elevations of 1300 to 1600 meters as a mini-miniature sized, cool growing, caespitose epiphyte with stout, erect ramicauls enveloped by 2 to 3 thin, tubular sheaths and carrying a single, apical, erect, thickly coriaceous, elliptical, subacute to obtuse, denticulate-erose margins, cuneate below into the petiolate base leaf that blooms in the spring and fall on a .04 to .2" [1 to 5 mm] long, single flowered inflorescence arising laterally from the ramicaul and has an oblique, acute, longer than the ovary floral bract.

"As in many others from DR the margins of the leaves of this are minutely denticulate. The short stemmed flower is borne singly, the dorsal sepal is deeply connate to a concave synsepal, the petals are narrowly oblong and the lip is bilamellate above the middle, the lamina fitting between broaad, descending wings of the column from above."
