Monstera dubia is a species of plant in the genus Monstera native to Central and South America.

[1] M. dubia is known for the dramatic transformation its foliage makes as it climbs from seed stage on the forest floor, to shingling closely up a host tree trunk or other surface, until mature leaves with fenestrations similar to Monstera deliciosa appear.

[2] This transformation is an example of leaf dimorphism.

[3] Dubia refers to dubious, because authors were not certain that the species fell within the genus Marcgravia, where it was initially placed.
