Discussion

Variety oblongifolia largely replaces var. miniata from the upper elevations of the San Bernardino and eastern San Gabriel mountains in San Bernardino County, as well as the Cuyamaca and Laguna mountains in San Diego County, and it extends southward into the mountains of northwestern Baja California, particularly in the Sierra Juarez. Variety oblongifolia rarely has oblong leaves, but it differs from var. miniata in its densely puberulent stems and leaves, unusually long, narrow, acuminate calyx lobes, usually ascending-appressed leaves that are often brittle and slightly fleshy, and usually pale orange-red inflorescences. While they are occasionally found singly in populations of the nominate variety, the combination of these otherwise unusual characters is unique in var. oblongifolia.
