leafy; in some species wanting, the Jlower-sfalks being

 simple, various in breadth ; either undivided, entire, 

 toothed, orpinnatifid; mostly rough or hairy; sometimes, 

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

 in general is milky, and more or less bitter, but the^e 

 qualities are in some instances hardly perceptible.

Perennial. July. 



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

 ■rigid hairs, tawny at their base. Leaves almost entirely radical, 

 asoUtary one being only now an-d then elevated a little way up 

 the stalk, all of them of a narrow obovate figure, tapering at the 

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

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

 solitary, erect, bearing a large, bright yellow^oii'er, whose calyx 

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

 Seeds minutely dotted, angular, reddish- brown. Down rough; 



H. alpinum, Ehrh. Herb. 79, and especially his strongly and sharply 

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

 dark calyx, and hairy^07e^\ of our plant, but they are far more 

 gigantic than any specimens of British growth that 1 have seen. 

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

 not H. villosum of Engl. Bot. t. 2379, nor H. pumilum of Will- 

 denow, both of which are caulescent.
