Flower Size .2" [5 mm]
Found in Zamora Chinchipe province of Ecuador in cloud forests at elevations of 2450 to 2700 meters as a mini-miniature sized, cold growing epiphyte with a slender, erect ramicaul enveloped by 5 to 8 lepanthiform sheaths with conspicuously dilated, ciliate ostia and carrying a single, apical, erect, coriaceous, broadly ovate, subacute to obtuse, rounded and contracted below into the petiolate base leaf that blooms in the later summer and early fall on a filiform, loose, distichous, flexuous, to 5.4" [13.5 cm] long, successively single, many flowered inflorescence.
"This little species with long, loose, flexuous racemes has small, red flowers with green or yellow margins, very similar to those of L disjuncta from the same area. L disjuncta however has short, congested racemes. The conectives of the lip of L exogena form a narrow body with the appendix located externally at the base. The connectives of L disjuncta are not united into a body, but the similar appendixz originating from beneath the column is in approximatley the same position as that of L exogena." Luer 1996
