Posted on April 11, 2026

Finding
SITF has determined this plant to be Trichopilia fragrans, not Trichopilia peruviana (Apr 2026).Using the key in the "Orchids of Peru", (https://www.biodiversitylibrary.org/page/2464900#page/26/mode/1up), this keys to T. fragrans. T. fragrans and this plant have: conspicuous pseudobulbs and leaves that have distinct leaf blades; peruviana flowers are very small (sepals less than 2.5 cm long); these are 4.4 cm long; the leaf form is sessile, not petiolate; the pseudobulb shape is flatten and ovoid; not linear-cylindric. There are two species that share these similar traits: T. fragrans and T. grata. In T. fragrans, the crest is a simple, more or less a linear lump sitting on the yellow spot. T. grata differs in that the crest is significantly wider at the top and abruptly terminated at the outer end giving the look of a chopped off triangle (trapezoid). This crest is not noticeably wider at the top than at the bottom, so not T. grata.
