Leaves erect to ascending; petioles often purplish, margins ciliate to tomentose; blades usually linear to oblanceolate, rarely spatulate, 10-40(-50) cm, margins usually dentate to lobed, or laciniately pinnatifid, rarely subentire, lobes 3-5 pairs, opposite to irregular, linear to lanceolate, usually antrorse, sometimes spreading; lobules often present, faces ± villous to canescent. Peduncles elongating after flowering, (15-)25-60(-96) cm in fruit, ± glabrate, or apically villous to tomentose, eglandular, sometimes bracteate.
