Flower Size .12" [3 mm]

Found in Nariño department of Colombia at elevations around 1800 meters as a small sized, cool growing densely caespitose epiphyte with erect, slender ramicauls enveloped by a close, tubular sheath on the middle third and another 2 below and at the base and carrying a single, apical, erect, coriaceous, elliptical, acute to subacute, cuneate below into the petiolate base leaf that blooms in the early winter on a single, arising through a slender spathe from a node below the apex of the ramicaul, peduncle .8" [2 cm] long, rachis to 4.4" [11 cm] long, erect, secund, congested, simultaneously many flowered inflorescence with tubular, obtuse, as long as the ovary floral bracts and carrying yellow flowers.

"This caespitose species, cultivated by the La Planada Research Center, is distinguished by a congested, secund raceme of small flowers that exceeds the leaf. The sepals are three-veined with the lateral sepals shallowly connate and antrorse to form a concave synsepal. This is one of many that are not clearly defined as belonging to section Humboldtia. The petals are three-veined, and the lip is type A with a broadly obtuse apex." Luer 2016
