Found in Santander Colombia at elevations around 1900 meters as a mini-miniature sized, cool to cold growing epiphtye with small, linear-elliptic pseduobulbs enveloped by 3 papyraceous sheaths and carrying a single, fleshy, green, elliptic-ovate to oblong, obtuse to minutely retuse sesile leaf that blooms in the summer on a terete, to 1" [2.5 cm] long, single [rarely 2] flowered inflorescence with ovate acute floral bracts
This species is part of the T pulchrum group which includes T longicalcaratum, T obcordilabium, T pulchrum and T loyalicum but differs in that the keels of the obovate lip are glabrous or obscurely puberulent and the floral segments are greenish white and never have purple spots or blotches.
