[deadasthedodo.com] Historical range, Presumed extinct: The Santa Catalina Monkeyflower is apparently known exclusively from the type material that was collected in 1901 or 1904 (depending on the source); the species was restricted to Santa Catalina Island in the Channel Islands group offshore the Pacific coast of California, USA.
The species presumably disappeared due to grazing by introduced ungulates and is now considered extinct. (contributed by Mary Ann Machi)
