quality, as old herbalists record. Gerarde justly observes that 

 the hot acrid Hijdrocotijle was very unluckily used by some in- 

 stead of the Cotyledon.

 V. 3.471. 



On moist rocks and old walls, very rare. 



In the West Riding of Yorkshire. Mr. Tojield. Seen by Mr. Hud- 

 son, in the garden of a Mr. Clement, who received it from 

 Somersetshire. Roots, given by Mr. Hudson to the Chelsea 

 garden, have long flourished there, and from thence the figure 

 in Engl. But. was drawn. 



Perennial. Jtilij. 



Root fleshy and creeping. Herb smooth, taller than the foregoing, 

 a foot or more in height. Lower leaves only very slightly pel- 

 tate ; the rest kidney-shaped, obovate, or ovate, strongly ere- 

 nate or toothed ; the uppermost gradually diminishing to ovate, 

 toothed bracteas, on short stalks, solitary under each flower. 

 Fl. numerous, twice the size of the last, erect, of a full yellow, 

 in a leafy, simple or branched, spike, rather than cluster, the 

 partial stalks being very short, or scarcely any. Cor. divided half 

 way down, its segments bearing the 5 smaller stamens. Cal. 

 separated almost to the base. 



Linnaeus confused himself among the synonyms of old writers, and 

 was led to make this the type of his C. Umbilicus. It appears 

 however to be specifically distinct, and not to have been figured 

 by any botanist before Dodart.
