A Mimulus guttatus B Mimulus × smithii (Mimulus luteus luteus × Mimulus luteus variegatus) C Mimulus × robertsii (Mimulus guttatus × Mimulus luteus), and D Mimulus peregrinus. Each taxon is represented by flowers from two individuals from a single locality to illustrate within-population variability: Mimulus guttatus = Dunblane, Perthshire; Mimulus × smithii = Coldstream, Scottish Borders; Mimulus × robertsii = Nenthall, Cumbria; Mimulus peregrinus = Leadhills, South Lanarkshire.
