Chromatographic and spectrophotometric techniques were used to identify the anthocyanin pigments present in Mimulus cardinalis and its related species of section Erythranthe of the genus Mimulus (Scrophulariaceae). On the basis of rigorous tests, the flowers of M. cardinalis were found to contain pelargonidin‐3‐glucoside, pelargonidin‐3‐rhamnoglucoside, the caffeoyl ester of pelargonidin‐3‐glucoside, cyanidin‐3‐glucoside, cyanidin‐3‐rhamnoglucoside, and the caffeoyl ester of cyanidin‐3‐glucoside. Qualitatively all members of the group contain these six anthocyanins except M. lewisii. All of its populations lack the pelargonidin glycosides and some lack, in addition, the cyanidin‐3‐rhamnoglucoside. The striking differences in flower color and intensity appear to be due to quantitative differences not here analyzed.
