Marantaceae are found in the lowland tropical forests of Asia, Africa and the Americas.
Marantaceae are readily distinguished from all other plant families by 2 distinctive vegetative characters: 1) the sigmoid (S-shaped) lateral veins and the numerous parallel cross veins of the leaf blade and 2) the presence of a region of specialized cells just below the blade, termed the pulvinus, which controls the movement of the leaves.
Marantaceae floral structure initially evolved in response to bee pollination and the vast majority are still bee pollinated.

Marantaceae are clearly monophyletic, uniquely defined by two vegetative traits: leaf venation of broadly sigmoidally-curved (S-shaped) lateral veins with numerous, regular, parallel cross veinlets (attached at right angles) between them and the pulvinus at the base of the leaf blade.
Florally, Marantaceae are characterized by their highly modified staminodes and unusual pollination mechanism: explosive, secondary pollen presentation.
Within the Zingiberales, Marantaceae are most closely related to Cannaceae, with in which it had been merged untithey were originally placed.l K. Koch (1857) recognized the taxon as a distinct family.

Starting with savanna along its northern and eastern borders, the vegetation changes to a variety of tropical rain forest, from pioneer forest to Marantaceae forest and finally to mature forest in the southwestern half of the park.
The savannas in Lopé, completely enclosed within the vast forest of the Congo Basin, are remnants of the savanna expansion in Africa during the last ice age and its subsequent periods of drier and cooler climate.
Beyond the newly colonized forest is the Marantaceae forest.

However, instead of grasses, the forest floor is densely covered by herbaceous plants from the wild ginger family (Zingiberaceae) and the Marantaceae family.
The Marantaceae forest is much more extensive south of the Tri-National Park; it is also found in another of our study sites, the Lopé National Park of Gabon.
Although some speculate that this is a relic of past agricultural activities in the region, there is a lack of concrete evidence to support this claim.
