Discussion
Iliamna latibracteata is distinctive in having large involucral bracts, which more or less envelop the calyx and equal or surpass it in length. It occurs in the Klamath and Siskiyou mountains of Del Norte and Humboldt counties in California, north to Coos, Curry, Douglas, Jackson, and Josephine counties in Oregon, with an eastern outlying station reported from Mount Shasta, California.
