Found in lowland Antioquia department of Colombia at elevations around 800 meters as a mini-miniature sized, warm growing, caespitose epiphyte with a slender, erect ramicaul enveloped by 2 thin, tubular sheaths and carrying a single, apical, erect, narrowly elliptical-obovate, acute to subacute, gradually narrowing below into the indistinct, subpetiolate base leaf that blooms in the late winter and early spring on a congested fascile of erect, slender, [3.5 to 4.5 cm] long, successively single, few flowered inflorescence with imbricating, thin, half as long as the pedicel floral bracts.
