Found in central Colombia in dense, dwarf, mossy, cloud forests at elevations of 1800 to 3300 meters, as a large to giant sized, cool to cold growing terrestrial with elongate, leafy stems enveloped by many nerved, striate, leafbearing sheaths and carrying erect-patent, ligulate-oblong, subacute, coriaceous leaves that blooms in the late spring and summer on a terminal, shortly pedunculate to 2.8" [7 cm] long, paniculate, to 5.2" [13 cm] long, densely many flowered inflorescence with lanceolate, acuminate floral bracts and carrying sweetly fragrant flowers

This species has white pedicels and a white back to the flowers which makes it very noticable in the forest as well as its very strong fragrance that can be detected from several meters away.
