Leaf anatomical data from 13 taxa of the Muhlenbergia montana complex were surveyed, and 18 critical characters were found. Results obtained from the phenetic analysis of anatomical data have given independent data to compare with the morphological, phytogeographical, and flavonoid data (previously reported) in determining the relationships of the species. An anatomical dendogram illustrates a close corroboration. Leaf anatomy clearly supports the recognition of a close relationship among the two taxa — M. virescens and M. quadridentata— as has been suggested in previous reports. Therefore, a change of level is suggested in which M. quadridentata (H.B.K.) Kunth is proposed here as M. virescens (H.B.K.) Kunth ssp. quadridentata (H.B.K.) Herrera (comb. nov.).
