Cauline leaves: proximal (1–) 2-pinnately lobed (lobes linear, apices obtuse or acute), ultimate margins entire or denticulate, apices usually obtuse; distal linear to filiform (sometimes pinnately lobed, lobes linear to filiform). Arrays of heads relatively crowded. Cypselae 1.8–2.2 mm. 2n = 18.


Phenology: Flowering Feb–Dec.
