Montrichardia is a genus of flowering plants in the familyAraceae. It contains two species, Montrichardia arborescens and Montrichardia linifera, and one extinct species Montrichardia aquatica.[1][2] The genus is helophytic and distributed in tropical America (West Indies, Belize, Brazil, Colombia, Costa Rica, French Guiana, Guatemala, Guyana, Honduras, Nicaragua, Panama, Peru, Puerto Rico, Suriname, Trinidad, Tobago, and Venezuela). The extinct species M. aquatica is known from fossils found in a Neotropicalrainforest environment preserved in the PaleoceneCerrejón Formation of Colombia.[2] Living Montrichardia species have a diploidchromosome number of 2n=48.[3]

M. linifera and M. arborescens can be differentiated by the appearance of their stem, leaves and spathe, with M. linifera having a stem described as "bamboo-like, smooth or tuberculate (never aculeate)" and M. arborescens having a "moderately slender, prominently aculeate" stem, among other differences.[4]
