Discussion

Variety tracyi is possibly adventive in northern Alabama. Spring-blooming plants of var. graminifolia can look similar because of aberrant development of only a few, and therefore larger, heads. This is the only variety with sometimes moderately long-pilose disc corolla throats and lobes throughout.
