Common Name The Two Hooked Trichosalpinx [refers to the basal lobes of the lip]

Flower Size .4" [1 cm]

Found in southern Ecuador in montane forests at elevations of 750 to 1200 meters as a miniature sized, warm to cool, pendant growing epiphyte with erect, slender ramicauls that produce other ramicauls from the apex and enveloped by 2 to 9, closely adpressed, lepanthiform sheaths with ciliate ostia and carrying a single, apical, coriaceous, elliptical to narrowly elliptical, acute, contracted below into the petiolate base leaf that blooms in the summer on a loose, lightly flexuous, 8" [20 cm] long, flexible, simultaneously several to many flowered, racemose inflorescence arising from near the apex of the ramicaul.

"Related to T montana but differs in the frequently prolific habit of the ramicauls, narrowly elliptic leaves that are far exceeded by a showy, lax, simultaneously flowered raceme with bright yellow flowers that are often striped in red and a large, brown lip. The sepals are long-acuminate with the laterals free and diverging. The petals are obtuse with the apical margin more or less irregular. The lip is distinctive with a pair of erect, uncinate basal lobes. The size and shape of the basal lobes is variable. Sometimes they are half the dimensions of the largest." Luer 1997
