to the stalk at night. Seeds obovate, furrowed, entirely without 

 any border, or crown, but sometimes, as Haller describes them, 

 rough with minute tubercles. This however is not invariable. 

 Recept. highly conical, almost cylindrical, beset with slender 

 permanent scales. 

 Every part of the plant is fetid and acrid, blistering the skin when 

 much handled, which Dr. Hooker justly attributes to the minute 

 resinous dots sprinkled over its surface. Dillenius has noticed 

 a variety with double flowers.

Biennial } July, August. 



Stem bushy, corymbose, erect, 1 8 inches high, leafy, angular, solid, 

 downy or cottony, especially in the upper part. Leaves sessile, 

 doubly and accurately pinnatifid, with sharp, partly notched, 

 parallel, decurrent segments ; green, rough, or hairy, above ; 

 white and cottony beneath. Ft. on long, terminal, striated, 

 downy stalks, solitary, large, of a bright yellow in the rays as 

 well as disk. Cat. downy, or shaggy, especially the inner scales. 

 Seeds oblong, quadrangular, striated, each crowned with a nar-

 they are much used in Sweden. Sometimes the radius varies 

 to a pale straw-colour. There are several handsome exotic spe- 

 cies nearly akin to this.
