Rhodospatha moritziana is distinguished by having terrestrial habit, short internodes, relatively broad blades and inflorescences with whitish spathes, and uniform spadices with naked bisexual flowers. So far, R. moritziana is the only species with consistent terrestrial habit of the genus in Panama . Due to its terrestrial habit, it is possible to confuse the individuals of R. moritziana with those of the genus Spathiphyllum . On Cerro Pirre, R. moritziana differs from all species of Spathiphyllum by having reddish-punctate blades on the lower surface, with numerous primary lateral veins. Distribution and ecology.
