Flower Size .4" [1 cm]
Found in Morona-Santiago province of Ecuador in tall rainforests along streams at an elevation of 1600 meters as a mini-miniature sized, caespitose, cool growing epiphyte with erect ramicauls enveloped by 2 to 3 loose, tubular sheaths carrying a single apical, erect, coriaceous, purple spotting on the underside, narrowly elliptic, subacute, narrowing below into the base leaf that blooms in the fall on an erect, arising from low on the ramicaul, peduncle slender, 1.2 to 1.6" [3 to 4 cm] long, with a bract near the base, successively single, 2 to 5 flowered, racemose, smooth inflorescence and holding the flower well above the leaf with shorter than the pedicel floral bracts.
"Vegetatively this specis is similar to Trisetella triglochin but the flowers have only a shallow, obtuse mentum. Both the yellow dorsal sepal and the red purple synsepal of T andeettae bordered in yellow are minutely ciliate. The tail of the dorsal sepal is clavate, and the tails of the synsepal are apical [not lateral] and short. However the degree of thickending of the apex of the dordal sepal and the length of the tails of the lateral sepals is variable in manty species in the genus. The petals , lip and column aete not remarkably deffent from its relatives.
