Three recent phylogenetic studies have used DNA sequence data to examine evolutionary relationships in Amsinckiinae (Boraginaceae). In each of these studies, the genus Plagiobothrys Fisch. u0026 C. A. Mey. has been recovered as non-monophyletic. So that only monophyletic groups are recognized, two new genus names are provided here: Amsinckiopsis (I. M. Johnst.) Guilliams, Hasenstab u0026 B. G. Baldwin and Simpsonanthus Guilliams, Hasenstab u0026 B. G. Baldwin. The new combination P. collinus (Phil.) I. M. Johnst. var. pringlei (Greene) Guilliams u0026 B. G. Baldwin is given for plants from Arizona that were found to be phylogenetically nested within P. collinus. The genus name Sonnea Greene is lectotypified.
