Montia parvifolia (Moc. ex DC.) Greene var. batholithica Ertter & C.A.M. Prent. (Montiaceae) is described as a new variety from high elevations (2100–2800 m) in central Idaho and adjacent Montana, based on an overview of variation within the species using a combination of standard taxonomic analysis of herbarium specimens, morphometric analysis, fieldwork, and common garden studies. Taxonomic history of the species is summarized, morphology and life history are clarified, and variation elsewhere in the species is also briefly addressed.
