Flower Size 3/8" [1 cm]

This miniature sized, cool growing, epiphytic species can be found in Panama and Costa Rica in lower montane rain forests at elevations of 1200 to 1800 meters with thin ramicauls enveloped basally by several tubular sheaths and carrying a single, apical, oblong-oblanceolate, conduplicate at the base leaves and blooms with an apical, 1 1/4" to 4" [3 to 10 cm] long, racemose, laxly several [6 to 8] flowered inflorescence arising from a spathe at the leaf base, with triangular bracts, which is longer than the leaves and occurs in the winter and spring. An easy diagnostic characteristic of this species is the white flowers and the shallowly, saccate pilose synsepal, has a resemblance to a toilet seat.
