Common Name The Rio Viao Lepanthes [refers to where the orchid was discovered]

Flower Size .08" [2 mm]

Found in Antioquia department of Colombia on the central cordillera of the Andes in cloud forests at elevations around 2000 meters as a mini-miniature sized, cool to cold growing epiphyte with slender, erect ramicauls enveloped completely by 6 to 7, microscopically ciliate lepanthiform sheaths with oblique ostia and carrying a single, apical, erect, thickly coriaceous, very narrowly ovate, acute, cuneate and contracted below into the petiolate base leaf that blooms in the late spring on a, filiform, congested, distichous, .56 to .64 [1.4 to 1.6 cm] long including the .16 to .24 [4 to 6 mm] peduncle, successively single, many flowered inflorescence arising on the back of the leaf with muriculate floral bracts.

Similar to L petalopterx of the western cordillera of the Andes but it has minutely denticulate sepals and 2 veined lateral sepals and the petals has obliquely truncate upper and lower lobes. The lips of both species are essentially the same.

Also similar to L pleurorachis, and L anchicayae
