leafy ; in some species wanting, the Jlo-joer-sialks being

 simple, various in breadth ; either undivided, entire, 

 toothed, or pinnatifid; mostly rough or hairy ; sometimes 

 smooth. Fl. yellow, very seldom reddish. The herbage 

 in general is milky, and more or less bitter, but these 

 qualities are in some instances hardly perceptible.

Perennial. Jidxj. 



Root blackish, rather woody. Herh clothed with prominent, hoary, 

 ri^id hairs, tawny at their base. Leaves almost entirely radical, 

 asolitary one being only now and then elevated a little way up 

 the stalk, all of them of a narrow obovate figure, ta))ering at the 

 base, either quite entire, or slightly and distantly toothed, about 

 2 inches long, dark green and equally hairy on both sides. Stalk 

 solitary, erect, bearing a large, bright yellow^ozfer, whose calyx 

 is black and very hairy. Tube of each^orei externally hairy. 

 Seeds minutely dotted, angular, reddish-brown. Doicn rough. 



H. alpinum, Ehrli. Herh. 79, and especially his strongly and sharply 

 toothed variety 89, with a divided stalk, have indeed the shaggy 

 dark calyx, and \\&\xy florets, of our plant, but they are far more 

 gigantic than any specimens of British growth that I have seen. 

 This n. 89 may perhaps be H. Halleri, Hook. Scot. 229, but it is 

 not H. villosum of EngL Bot. t. 2379, nor H. pamilnm of Will- 

 denow, both of wliich are caulescent.
