A leaf anatomical survey was conducted to gather critical data for interpreting relationships among 32 species of annual Muhlenbergia . Phenetic analyses, utilizing 14 anatomical characters, support recognition of four major species groups. These four major species groups are not concordant with previously reported groups. Muhlenbergia brandegei , known only from three islands in Baja California Sur, is believed to be more closely related to M. appressa, M. microsperma , and M. tenuifolia , rather than, M. biloba , as suggested in prior publication. Muhlenbergia diversiglumis is morphologically similar to species of Pereilema and does not show close affinities with other annual species of Muhlenbergia . Anatomically, M. ciliata, M. pectinata , and M. tenella are very similar and form the most distinctive group among the annual Muhlenbergia .
