slender bristles of the receptacle, and the glandular foliage. 
10, 8. Radula (Harv.); stem herbaceous, erect, angle-furrowed, rough 
with hard points, racemoso-corymbose at the summit; radical leaves 
obovate-oblong, obtuse, tapering much at base, some subpetiolate, repand

This has much of the habit and foliage of 8. Rhapontica; but besides the want of

petioles, obovate-oblong, tapering to the base, pinnatifid, the lobes 
rounded, with a sub-revolute, unequally many-spined margin, cauline
