Identification. This species is characterized by having terrestrial habit, minutely denticulated blade margins (when fresh), typically lanceolate, obtuse to rounded at base; inflorescences with green lanceolate spathes, markedly decurrent on the peduncle, green spadices, and flowers with separate tepals and prominent conical styles. In the study area, only two species of the genus Spathiphyllum have been recorded and both are mainly differentiated by the morphology of the inflorescences and flowers (see couplet five of the key).

Distribution and ecology. Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Panama. This species of wide distribution, occurs in the semideciduous and evergreen forests of Cerro Pirre, between 90 and 800 m. Individuals of this species usually grow near rivers and streams or in very steep slopes areas.
