Found in Guatemala and Honduras at elevations around 1800 meters as a mini-miniature sized, cool growing epiphyte with a relatively stout, erect ramicaul enveloped by 6 to 8, ciliate, lepanthiform sheaths and carrying a single, apical, erect, rigidly coriaceous, elliptical, subacute to obtuse, contracted below into the petiolate base leaf that blooms in the late fall and early winter on an erect, lax, filiform, .6 to 1" [1.5 to 2.5 cm] long including the .2 to .32" [5 to 8 mm] long peduncle, simultaneously 3 to 6 flowered inflorescence arising from near the apex of the ramicaul.

Similar to T blaisdelii but differs in the sparsely ciliate sepals with the dorsal sepal obtuse and the laterals connate to near the middle and reflexed, The petals are glabrous, triangular and acute and the lip is finely ciliate and has a convex apex and an erect, sundial-like callus similar to that of T memor at the base and the callus has a pair of low fork-like calli above the middle.
