CRYPTOGAMIA ALGM. 249 



The leaves are varioufly laciniated, in a good mea» 

 fure like the radical leaves of the SeneciGjacohaa 

 or common ragwort ; when young and frefh, of 

 a dull green,- but, when old or dry, of a fufcous 

 or reddifh brown colour. Their upper fide is 

 fmooth and pitted, their under one covered v/itb 

 a dark, fufcous fpongy down, almoft black to- 

 wards the bafe of the leaves, but light-brown or 

 buff-colour'd near the extremities of the feo-- 

 ments. Intcrfperfed among this down are many 

 little holes or cavities, which appear like round 

 white points or dots. 

 The fhields, or/)^//^, are very rarely found. They 

 grow at the extremities of the fegments, of a 

 roundifh or oval form, very fmall, and chefnut- 

 colour'd. Befides which fhields, the difc of the 

 leaves, and the prominent wrinkles on the fur- 

 face, are often fprinkled with brownifli or whitifh 

 farinaceous tubercles. In one fpecimcn we ob- 

 ferved thefe tubercles, and the little holes amonoft 

 the dov/n, of a bright yellow colour. 

 The dry leaves, when foak'd in water, yield a 

 ftrong urinous fmeli.
