Flower Size 2/4" [2 cm]

Found in Peru in very wet montane forests at elevations of 1800 to 1850 meters as a miniature, caespitose, cool growing epiphyte with a minute, inconspicuous ramicaul enveloped basally by 2 to 3 tubular sheaths with a single, apical, erect, elliptic, oblong-obovate, spatulate, elongate channeled petiole, coriaceous, very dark green leaf with a tridenticulate apex and blooms on an ascending to horizontal, 1/2 to 1" [1.25 to 2.5 cm] long, slender inflorescence arising from low on the ramicaul with a single, basal, infundibuliform bract and a small, tubular floral bract with the single flower held below the leaves occuring in nature in the spring.
