Discussion
Plants of subsp. pumila in the San Gabriel Mountains are rather uniformly small, with the rosette leaves rhomboid and short-acuminate to cuspidate. Taken by themselves, they would seem a quite well-distinguished subspecies, and many plants of the Santa Lucia Mountains are similar. Plants of the San Bernardino Mountains are similar but apparently more variable; in the Santa Lucia Mountains the plants are perhaps even more variable, some like subsp. cymosa. Thus there is no clear line between the two subspecies.
