Common Name or Meaning The Mountain Growing Trichosalpinx
Flower Size 1/2" [1.25 cm]
Found in Minas Gerais, Rio de Janiero, Santa Catarina and Sao Paulo states of Brazil as well as Colombia, Ecuador, Peru and Bolivia at elevations of 1000 to 4000 as a miniature, cool to cold growing epiphyte with erect, thick ramicauls enveloped basally by 4 to 9 dark, closely appressed, lepanthiform sheaths with thick, ciliate ostia and carrys a single, apical, erect, coriacceous, narrowly elliptical, acute leaf that is cuneate below into the petiole that blooms in the spring and fall in Brazil on a loose, flexous, flexible, successively several flowered, racemose, 8" [20 cm] long inflorescence arising from near the apex of the ramicaul, and frequently carrying 2 simulataneously opening, pendant flowers.
I found the orchid in the photographs above in a small valley in eastern Sao Paulo Brazil next to a pond in a microenvironment that was constantly extra humid, to the point that my camera fogged [evident in Photo #2] over from the inside and this was the last clear picture of that day and 1/2 of the next.
"Similar to T dirhamphis but differs in the narrowly elliptical leaves that are far exceeded by the lax, flexible, arching, successively flowered raceme [simultaneous in T dirhamphis] and long acuminate sepals with the laterals connate to about the middle into an ovate blade [the lateral sepals of T dirhamphis are free and spreading]. The petals are obtuse with the apical margin more or less irregular. The lip is distinctive by an erect pair of uncinate, basal lobes." Luer 1997
