PlaceOfPublication Fedde Rep. Sp. Nov. Beih. 19:283. 1923.
Description Small, caespitose, epiphytic herbs. Secondary stems, very short, unifoliate, covered with a loose sheath. Leaves subcoriaceous, attenuated into a petiole at the base and with an abscission layer above the one at the apex of the secondary stem. Inflorescence terminal, usually one from each" stem, few-flowered; flowers small. Dorsal sepal broad, cucullate, enclosing the column. Lateral sepals con- nate into an oblong, bidentate lamina, longer than the dorsal sepal. Petals small, linear, inserted on the apex of the column-foot, retuse at the apex and with a large, auriculate, hood-shaped callus or ligule toward the base. Column arcuate, with a broad, membranaceous wing on each side; column-foot elongated, subequal to the column; pollinia 2, ceraceous.
Note A small genus of only two species, one Panamanian. Perhaps the most dis- tinctive of the Pleurothalloid genera in Central America.
