The new species is a locally common hemiepiphytic herb in the shady understory of the humid montane forests of the Atzalan municipio between 990 and 1430 m, where it cooccurs with other aroids, such as Anthurium scandens (Aubl.) Engl., Monstera egregia Schott, Philodendron sagittifolium Liebm., and Syngonium neglectum Schott. In this area, the natural forest vegetation in general is mostly fragmented and highly threatened by the transformation into pastures and plantations; thus, we believe that the populations of Monstera florescanoana do suffer severe anthropogenic pressures. However, the new species is probably not in danger of extinction, as we have observed some individuals growing in secondary vegetation close to a bridge along a roadside. In any case, the discovery of this new species demonstrates that more floristic inventories in remote and inaccessible areas are badly needed to complete our knowledge of the flora of Veracruz and along to take the necessary conservation measures for the remaining areas of high diversity and endemism.
