Discussion

Subspecies charlestonensis is known from the Mount Charleston region. Pennell and Clokey described this taxon based on its longer corolla and less pinnatifid leaves. Clokey later cited its restricted range in treating it as a subspecies. Examination of specimens of both subspecies confirmed that corolla length is a good discriminator, but leaf dissection is a less reliable character. A better character is the size of the primary leaf lobes; the lobes of subsp. charlestonensis are consistently smaller than those of subsp. semibarbata with much less overlap in size between the two.
