The genus Montrichardia are among the most remarkable emergent macrophytes in tropical wetlands. It occurs exclusively in the Neotropics and contains two living species, M. linifera (Arruda) Schott and M. arborescens (L.) Schott. Montrichardia linifera has been reported mainly in the Amazon basin (southern Venezuela to Guyana, Brazil, Ecuador and Peru), whereas M. arborescens occurs in Central America (Mexico to Panama), the Lesser Antilles and northern South America. Based on our review of herbarium specimens from Central America and Colombia, as well as field documentation in Panama, we hereby provide the first report of the occurrence of M. linifera in Panama, Central America and western Colombia. Furthermore, this finding represents the first record on the Pacific Slope for this species in the Neotropics. The habitat, ecology, life‐form, taxonomic remarks and morphological characteristics of the species are presented, discussed and illustrated. Additionally, a key for the species of the genus Montrichardia is included; we also provide a discussion about the helophyte concept for the genus Montrichardia.
