Pseudobombax tomentosum is a species of deciduous tree native to South America.

[2] Pseudobombax tomentosum is present on the outskirts of forests or roads in Brazil and Paraguay in South America.

[1][3] The large and rigid structure of the tree's flowers, combined with the flower's placement on the ends of branches and the chamber for nectar favors pollination by medium-sized mammals such as Caluromys as well as various bats.

The plant is predominantly pollinated by bats, but the species Caluromys lanatus frequents the tree in its native habitat as the placement and infrequency of flowers favors the movement of marsupials from one tree to another.

[2] As the wood of the tree is not very durable, it is used in low value goods such as toys, boxes, or wooden shoes.
