Common Name Blaisdell's Trichosalpinx [Australian Collector and Plantation manager in Guatemala 1800's]
Flower Size .12" [3mm]
Found in Mexico, Belize, Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, western Colombia and Ecuador in tall evergreen rain forests at elevations of 200 to 2500 meters as a miniature sized, hot to cold growing epiphyte with ramicauls enveloped by several loose, acuminate, ciliate, lepanthiform sheaths and carrying a single, apical, coriaceous, narrowly elliptic, acute, gradually narrows below into the conduplicate petiolate base leaf that blooms in the late spring through early winter on an erect, arising from the leaf base, peduncle filiiform, .2 to .8" [.5 to 2 cm] long, short, .6 to 1.6" [1.5 to 4 cm] long overall, lax to subdense, simultaneously several flowerd inflorescence with shorter than the ovary floral bracts.
Characterized by a relatively stout, more or less erect ramicaul and an elliptical leaf either narrow or broad. The short, congested inflorescence is shorter than the elaf. The sepals are variously ciliate, occasionally glabrous [what was T tamayoana second Luer drawing above]. The connivent lateral sepals recurvein varying degrees. As happens in the Pleurothallidinae "giant" flowers sometimes occur. Sepals very in length from .12" [3 mm] to as long as .4" [1 cm] without morphological differences. A distinctive large variation was recognized as T lankesteriana [the third Luer drawing above]. The petals are variously ciliate. The lip is oblong, obtuse or rounded apically, with ciliate margins and with a low, rounded, more or less cellular callus at the base." Luer 1997
