LATE

Common Name The Winged Petal Lepanthes [refers to the shape of the petals]

Flower Size .2" [5 mm]

Found in Choco' department of Colombia at elevations around 1600 meters as a mini-miniature sized, cool growing epiphyte with slender, erect, ramicauls enveloped by 6 to 7 microscopically ciliate-scabrous lepanthiform sheaths and carrying a single, apical, erect, coricaceous, narrowly ovate, acute, cuneate below into the petiolate base leaf that blooms in the late summer, fall and early winter on a slender, congested, distichous, .6 to .68" [1.5 to 1.7 cm] long including the .4 to .48" [1 to 1.2 cm] long peduncle, successively several flowered inflorescence with muricate floral bracts.

"A short raceme is borne beside a narrowly ovate leaf. The sepals are elliptical and obtuse. Most distinctive is the pair of large, winglike petals. The obliquely subquadrate lobes are almost mirror images of each other. The short column is surrounded by a reniform lip that is rounded when expanded. A microscopic lobule is present at the base in the shallow, apical incision." Luer & Escobar 1994

Similar to L viahoensis of the central cordillera of the Andes but L petalopterx 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
