Discussion

Subspecies trifidus grows in the foothills of the Sierra Nevada. T. I. Chuang and L. R. Heckard (1986) recognized subsp. hansenii as distinct based on its shallowly cleft inflorescence bracts and robust distal branches. These characteristics do not distinguish subsp. hansenii but occur occasionally in plants of both subsp. hansenii and subsp. trifidus. Also, the plants they separated as subsp. hansenii occur in two disjunct populations, separated geographically by their subsp. trifidus. Combining the subspecies creates a geographically, ecologically, and morphologically coherent group.
