2014 37E(2) 79-87 Thomas B. Croat, Vincent Pelletier, Ludovic Salomon, Jean Weigel New species of Xanthosoma (Araceae) from Western French Guiana (Read)
ABSTRACT: A new species of helophytic Xanthosoma, X. nodosum Croat & V. Pelletier, is reported for western French Guiana. The species is a member of section Xanthosoma and is allied with X. sagittifolium (L.) Schott and X. jacquinii Schott but differs from both of those species by its hydric habit and conspicuously arrayed short knobby rootlike propagules on its stem. In addition, Xanthosoma jacquinii also differs by having a spathe tube which is dark purple on the inside.
