Common Name Deburghraeve's Trisetella [Belgian Orchid Enthusiast current]

Flower Size .4" [1 cm]

Most likely found in western South America as a mini-miniature sized epiphyte with erect ramicauls enveloped by 2 to 34, tubular papery sheaths and carrying an erect, coarsely leathery, somewhat succulent, narrowly linear, dark green leaf that blooms in the late spring on an erect, smooth, provided with 3 membraneous bracts, 1.4 to 1.6" [3.5 to 4 cm] long, successively single, to 3 flowered inflorescence witha a shorter than the pedicel floral bract..

"It differs from the similar Trisetella escobarii by the dominant, rhombus-shaped callus on the lip and the subpandurate petals which are just a little wider on the apex and also by the sepal-tails which are pointing forewards, versus the sepal-tails of Trisetella escobarii which are protruding to the side and upwards."
