Main distinction between varieties of C. nuttallii treated in TJM (1993) is differences in rhizomal leaves; however, rhizomal leaf morphology has been found to be highly variable and generally not useful for recognizing varieties within the species. Needs field surveys and further study. A synonym of C. nuttallii in TJM 2.
