Montrichardia is a genus of flowering plants in the family Araceae. 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 Neotropical rainforest environment preserved in the Paleocene Cerrejón Formation of Colombia.[2] Living Montrichardia species have a diploid chromosome number of 2n=48.[3]

Species


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]
