CRYPTOGAMIA ALG^. • I55 



This is found in the fame places, mix'd with the 

 foregoing. 



The color and fubftance is the fame as in the pre- 

 ceding. 



The leaves are flat and doubly pinnatifid j the 

 fegments about a quarter of an inch wide j the 

 dents flat, obtufe, and callous on the mar- 

 gins. 



It is probably no more than a variety of the lafl ; 

 but though the plant is generally larger, and 

 the fegments wider, it is fomewhat remarkable 

 that we never yet could difcover its feeds ; but 

 the dents always continue flat, without any 

 other figns of fru6lification than a callofity on 

 their margins. Pofllbly this Fucus may be 

 (dioecious, and this the male variety.
