Discussion

Diplacus brandegeei is known only from Santa Catalina (Los Angeles County), Santa Cruz (Santa Barbara County), and Guadalupe (Baja California) islands. The earliest name for the species, Mimulus latifolius A. Gray, was first transferred to Diplacus as D. latifolius (A. Gray) G. L. Nesom, but that name is a later homonym of D. latifolius Nuttall.
