Typification of names in Pachira aquatica Aubl. (Malvaceae, Bombacoideae) with a new combination and new status from the Brazilian Amazon forest

ABSTRACT A new combination and a new status, Pachira manausensis, is here proposed. After making field observations and analyzing type and herbarium specimens, we realized that P. aquatica var. manausensis should be treated as a species due to many morphological and distribution differences compared to the typical variety. We provide detailed descriptions and a distribution map, table, key, and plate to distinguish both species using morphological characteristics. Typifications and nomenclatural notes for related names were performed.
