Potentilla amicarum Ertter es el nombre que se proporciona para plantas de elevaciones altas (2700–3700 m) en el centro y sur de Sierra Nevada, así como las montañas White y Sweetwater de California, que han sido tratadas como P. drummondii o P. bruceae depauperadas, o también P. breweri con hojas subpinnadas. El nombre P. breweri var. viridis Jepson se ha aplicado a veces a estas plantas, pero el tipo de ese nombre se interpreta como el híbrido de P. wheeleri y P. breweri. Se hipotetiza un origen híbrido que implica a P. breweri, P. drummondii, y/o P. glaucophylla. El rango de tamaño y elevación de P. bruceae en tratamientos florísticos recientes se ajusta a los nuevos datos, y se discute la dis-tribución de P. drummondii en California.
