Full shade Cool Cold SpringSummer Fall

Common Name The Branching Trichosalpinx

Flower Size .2" [5 mm]

Found in Colombia, Ecuador and Bolivia at elevations of 1150 to 2800 meters as a mini-miniature to miniature sized, cool to cold growing epiphyte with a prolific, branching, erect to suberect rhizome giving rise to an ascending, slender ramicaul enveloped by 2 to 8, minutely ciliate, lepanthiform sheaths and carrying a single, apical, ascending, coriaceous, narrowly elliptical, acute, contracted below into the petiolate base leaf that blooms in the spring summer and fall on a loose, subflexuous, filiform, .8 to 2" [2 to 5 cm] long including the .2 to .6" [.5 to 1.5 cm] long peduncle, simultaneously several flowered inflorescence arising from near the apex of the ramicual.

"Distinguished by the branching, prolific ramicauls that bear narrowly elliptical leaves. The flowers are produced simultanously in racemes longer than the leaf. The sepals are free and narrowly acute and the lateral lobes of the lip are large, erect and antrorse with an irregular margin. There is no callus. The species is similar to T cedralensis but the former is distinguished by the usually larger flowers, tall, oblique, lateral lobes of the lip with the anterior margins of the lobes irregular and with antrorse, apical wings of the column. Large vegetative and floral forms of T acremona appear similar to T vagans and T dunstervillei but both these are distinguished by the low lateral lobes of the lip with tall keels on the disc."
