Biennial. August. 



A large and conspicuous plant, not easily overlooked. Root tap- 

 shaped. Stem 3 feet high, with numerous wide-spreading 

 branches, leafy, round, strongly furrowed, slightly hairy, full of 

 pith. Leaves sessile, not decurrent ; covered with close bris- 

 tles on the upper side, and with cottony down at the back ; their 

 lobes each tipped with a strong spine, and spreading alternately 

 in two directions, afford a singular and striking character. FL 

 numerous, very large, purple, solitary at the end of each branch, 

 with a smaller leaf or two close underneath. Cal. often about 

 3 inches in diameter, globose, or rather depressed, the purplish 

 tips of its scales projecting out of the mass of cottony wool, 

 which envelopes the whole calyx like a dense cobweb. Seeds 

 obovate, polished, with a feathery down. The radical leaves 

 are frequently 2 feet in length, and their lobes are disposed in 

 double ranks with singular exactness. Ft. occasionally white.
