Abstract

The genus Rollinsia Al-Shehbaz is reduced to synonymy of Dryopetalon A. Gray (Brassicaceae), and the characters distinguishing the latter from Sibara Greene and Thelypodiopsis Rydberg are discussed. An expanded description of Dryopetalon (southern United States and northern Mexico) and a key, synonymies, and distributions of its eight species are presented. The new combinations D. breedlovei (Rollins) Al-Shehbaz, D. byei (Rollins) Al-Shehbaz, D. paysonii (Rollins) Al-Shehbaz, and D. viereckii (O. E. Schulz) Al-Shehbaz are proposed. Dryopetalon purpureum Rollins is reduced to synonymy of D. palmeri (S. Watson) O. E. Schulz, and D. crenatum var. racemosum Rollins and D. runcinatum var. laxiflorum Rollins are reduced to synonymy of their respective species. Arabis endlichii O. E. Schulz is lectotypified.
