Found in Colombia and Ecuador? without locational data as a mini-miniature to miniature sized, shortly repent epiphyte with stout, erect, slightly compressed below, channeled above ramicauls enveloped by 2 to 3 near basal tubular sheaths and carrying a single, erect, coriaceous, elliptical, subacute, cuneate below into the sessile base leaf that blooms on an arching then pendent, arising through a spathe at the base of the leaf, peduncle ca. 4" [10 cm] long, to ca. 7.2" [18 cm] long overall, loosely simultaneously several-flowered inflorescence with oblique, acute, much shoerter than the pedicel floral bracts and carrying purple colored flowers.

"This species, apparently from Colombia, is characterized by stout, erect ramicauls with thick, elliptical leaves, and a longer, drooping, loosely flowered raceme of purple flowers. The very narrow, two-centimeter-long dorsal sepal is directed 90 degrees from the synsepal and descending rachis. The filiform tips of the petals are as long as the fimbriate blade below, and the lip is thick and ovoid with erect, rounded margins below the middle." Luer & Sijm
