Found in Pichincha province of Ecuador in montane cloud forests at elevations around 1650 to 2000 meters as a mini-miniature sized, cool growing epiphyte with erect, slender, ramicauls enveloped basally by 2 to 3, thin, ribbed, imbricating sheaths and carrying a single, apical, coriaceous, narrowly elliptical-obovate, subacute leaf that is narrowly cuneate below into the petiolate base and blooms in the late winter through fall on a weak, suberect, arising laterally from high on the ramicaul, peduncle filiform, .6 to 1.2" [1.5 to 3 cm] long , rachis 4 to 4.6" [10 to 11.5 cm] long, loose, distichous, flexuous, successively many flowered, racemose inflorescence with thin, shorter than the pedicel floral bracts.

Most notable for the extremely small flowers produced on a hair-like flexuous raceme much longer than the long-petiolate base leaves. The sepals and petals are less than .04" [1 mm] long and without any trace of a mid-vein." Luer 1984
