Discussion

Variety erubescens is localized and rare, known only from the eastern Scott Bar Mountains west of Yreka in Siskiyou County, and Trinity Mountain, Trinity County. Technically, the three bracts along the “branchlet” terminate a branch, and a peduncle extends from the whorl of bracts to the base of the involucre.
