Common Name Posada's Lepanthes [Colombian Orchid Nurseryman Current]

Flower Size .2" [5 mm]

Found in Colombia and Ecuador on the western slopes of the Andes at elevations around 1300 to 1900 meters as a small sized, warm to cool growing epiphyte with an erect, slender ramicaul enveloped by 11 to 23, minutely ciliate lepanthiform sheaths carrying a single, apical, suberect to spreading, thinly coriaceous, convex, elliptical-ovate, acute, cuneate to rounded and contracted below into the petiolate base leaf that blooms in the fall on a slender, congested, 1.2 to 2.6" [3 to 6.5 cm] long including the [1.5 to 5 cm] long peduncle, successively many flowered inflorescence arising on the back of the leaf.

This species is similar to L janitor, L agglutinata and L pilosaures which have petals lobes subequal in length and an uncinate process between the lobes but none of them share the unusual forked column and the bilobed stigma beneath that this species has.
