Notes: I've put the specific epithet of this plant in parentheses to indicate uncertainty; it is too immature to distinguish from the similar species, Perideridea bolanderi, within which it often grows in mixture.
Location: Downstream of the junction of the New Army Pass trail and Rock Creek trail (approximately 1/2 mile south of the Soldier Lake trail junction), on an unnamed tributary of Upper Rock Creek which is locally referred to as Army
Creek, Sequoia National Park, California
