Basal and lower stem leaves with 3-5 cm long petiole, lamina narrow oblong, 6-15 x 1.5-2 cm, 2-3-pinnatisect, with alternate primary lobes and linear-oblong, 2.5-5 x 0.5 mm, ± acute ultimate segments; upper leaves in the floral region subtending capitula simple, linear, approximate, 1.5-3 x c. 1 mm, acute.
