Common Name The Folded Lepanthes [refers to the folded margins of the lateral sepals]
Flower Size .12" [3 mm]
Found in the La Paz department of Bolivia in cloud forests at elevations around 2100 to 2900 meters as a mini-miniature sized, cold growing epiphyte with slender, erect ramicauls enveloped by 4 to 7, long-ciliate lepanthiform sheaths and carrying a single, apical, erect, coriaceous, purple suffused beneath, elliptical, acute, broadly cuneate below into the petiolate base leaf that blooms in the winter, spring and summer on a filiform, congested, distichous, .52 to .68" [1.3 to 1.7 cm] long including the .12 to .28" [3 to 7 mm] long peduncle, successively single, several flowered inflorescence arising on the back of the leaf.
Similar to L crista-piscis but it has a microscopic appendix within an acutely cleft sinus while L ptyxis has a lip with a thick, protuberent, rounded margin of the body with a snall rounded appendix.
Part of the group of species related to L complicata by the outer margins of the lateral sepals that are involute to expose the muriculate exterior. The majority of these are from Bolivia and are L ciliolata, L complicata, L crista-piscis, L echnida, L panisca, L pileata, L ptyxis, L ringens.
