Discussion

Yellow-flowered populations of Erythranthe cardinalis occur on Cedros Island, Baja California, and in the Siskiyou Mountains of Oregon (R. K. Vickery 1992). They have been documented also on Santa Cruz Island, California.

Populations of Erythranthe cardinalis in King and Yakima counties, Washington, are introduced and naturalized.
