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.

Two new species of Pachira (Bombacoideae, Malvaceae) and typification of Pachira patinoi

“…Several nomenclatural novelties were published recently for the genus Pachira Aubl., including lectotypifications, designations of epitypes, descriptions of new species and combinations (Andino & Fernández-Alonso 2018;Carvalho-Sobrinho & Dorr 2020;Carvalho-Sobrinho et al 2021;Yoshikawa et al 2022).…”

“…Thus, the genus Pachira now includes about 50 species (Tropicos.org 2022;Andino & Fernández-Alonso 2018;Carvalho-Sobrinho & Dorr 2020;Carvalho-Sobrinho et al 2021;Yoshikawa et al 2022), nearly half of which occur in Brazil: 18 species in Amazonian rainforest and 6 in Atlantic Rainforest (Mata Atlântica) and dry shrub-thorn forest (caatinga) (Flora & Funga do Brasil 2022).…”
