Discussion

Variety scaberrima is found in the inner Coast Ranges. Its branches tend to be longer on average; the arrays are thus rather large and open compared to undamaged plants of the other varieties. The smaller leaves of much branched and few-headed specimens of var. rudis can result in a habit similar to that of var. scaberrima. This could create confusion in identity if the ovate outer phyllaries of the latter are overlooked.
