Abstract
Three new species ofQuercus are described from northeastern Mexico:Quercus hintoniorum, Q. coahuilensis, andQ. miquihuanensis. These species form a morphological complex withQ. hypoxantha, which is shown to be of much more restricted distribution than previously reported. A key to the 4 species, full descriptions, synonymy, geographic distributions and illustrations are presented.
