Common Name The Naked Pleurothallis
Flower Size .6" or more [1.5 cm and more]
Found in Colombia, Federal District of Venezuela, Pastaza and Morona Santiago provinces of Ecuador, Huanuco and San Marin departments of Peru and Cochabamba department of Bolivia in wet montane forests at elevations of 500 to 2100 meters as a warm to cold growing, caespitose epiphyte with green or dark purple ramicauls with 2 to 3 basal, tubular scarious sheaths and a single, apical, elliptic-lanceolate to narrowly oblong, minutely bilobed, narrowing below into the conduplicate petiolate base leaf that blooms in the spring, fall on an apical, short, fasciculate, few flowered inflorescence with thin, tubular, half or less as long as the pedicel floral bracts and holding the semi-pendulous, successively opening, nodding singular flower near the leaf base.
Similar to P saueri but it is distinguished by a considerably larger plant size and flower, the sepals being 2" [5 cm] long. The lip lacks the usual prominent, three purple stripes of L. nuda; the basal lobes are rounded and concave anteriorly; and the midlobe is surrounded by a broad margin of dense, hairlike spicules."
