pinnately cut from the middle to deep, and have many prickles on the
margins. Flower heads, red-purple, 2-2.5cm in diameter, are set a
few together on branch tips. Involucres are bell-shaped or
hemispheric,1.7-2.7cm in width; involucral bracts line up in 7-8
rows, and outer and middle ones bend back. Bloom time: May-July. |
