Common Name The Ribbed Rachis Lepanthes [refers to the inflorescence]

Flower Size .08" [2 mm]

Found in Colombia and Ecuador in cold cloud forests at elevations around 1000 to 1650 meters as a mini-miniature sized, warm to cool growing epiphyte with an erect, slender ramicaul enveloped by 6 to 8, minutely scabrous, lepanthiform sheaths and carrying a single, apical, erect to suberect, coriaceous, narrowly ovate, acuminate to acute, obtuse to rounded below into the contracted, petiolate base leaf that blooms in the summer on a slender, flexuous, loose, to .44" [1.1 cm] long including the .24" [6 mm] long, successively single, few flowered inflorescence arising on the back of the leaf.

"Similar to L columbar, L viahoensis, L petalopterix and L anchicayae, but easily distinguished by the dense, distichous, comb-like racemes borne behind a small, narrowly ovate leaf carrying minute flowers with the three sepals similar, ellitical and essentially free: the transverse petals are acute, the upper lobe inconstantly bearing a small angle on the inner edge of the uper lobe: and a cordate, bladless lip shallowly retuse at the rounded apex with a minute apiculum." Luer 1996
