Corollas 6–7 mm. Cypselae (3.8–)4.5–5 mm.


Phenology: Flowering Aug–Oct.

Discussion

Known only from San Benito and Santa Clara counties, var. diabolica occurs in primarily inland, montane habitats. Var. diabolica differs from var. vernonioides in its resinous, usually densely stipitate-glandular vestiture (villous hairs lacking or sparse along the stems), consistently reduced, somewhat bractlike distal cauline leaves, and longer corollas and cypselae.
