Briquetiastrum: a new genus of Malvaceae and the redefinition of Briquetia

Abstract

A historical overview of the genus Briquetia, with an analysis of its circumscription conflicts and the proposal for a new genus, Briquetiastrum, based on new morphological studies and phytogeographical data were made. A taxonomic treatment and three new combinations from Briquetia to Briquetiastrum (Briquetiastrum inermis, B. spicatum and B. sonorae) are presented and Briquetiastrum sonorae is illustrated for the first time. Descriptions and a key to the treated species are included.
