Common Name The Membraneous Foliage Trichosalpinx

Flower Size very small

Found in Costa Rica and Panama in very wet forests at elevations of 950 to 1000 meters as a mini-miniature sized, warm growing prolific epiphyte with erect, superposed ramicauls enveloped completely by 4 to 7, tubular, minutely hispid sheaths that terminate in spreading ovate, ciliate margined mouths, carrying 1 or more, thick, elliptic, minutely denticulate margined, shortly petiolate base leaves that blooms in the summer on an erect, peduncle .4" [1 cm] long, .4 to .6" [1 to 1.5 cm] long overall, successively single, few flowered inflorescence carrying flowers with yellowish white sepals, transluscent petals and a pale yellow lip.

"Similar to T dura but differs in the leaves with a minutely denticulate margin, a short inflorescence that bears only 3 to 4 pale yellow, tiny flowers in slow succession. The sepals are carinate and acute, the minute, elliptical petals are without a discernable vein, the lip is oblong with the apex and base broadly rounded and the disc of the lip is only slightly thickened with three veins. A pair of wings extends forward from the apex of the column to flank the anther similar to the columnar wings of T tropida." Luer 1997
