Common Name The Naked Pleurothallis

Flower Size 1/2" or more [1.5 cm and more]

Found in wet montane forests of Colombia, Venezuela, Ecuador, Peru and Bolivia 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 that holds the semi-pendulous, successively opening, nodding singular flower near the leaf base.

Similar to P saueribut 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."
