02 2 CRYPTOGAMIA ALGiE. 



Podded Fucus. Anglis. 



Upon rocky fliores, but not very frequent. VII. 

 VIII. 



This Fucus varies from one to four feet in length ; 

 is of a hard coriaceous fubftance, a dark olive 

 color when frefh, but quite black when dry. 



The root or bafe by which it is faftened to the 

 rocks is a hard expanded horny lubftznce, as 

 in moft of the larger fpecies of .this genus. 



From this bafe arifes' a thick, opaque, narrow, 

 comprefs'd, waved llalk, nearly of equal fize 

 throughout, greatly branched, the branches 

 alternate, both dented on the edges with the 

 rudiments of Footftalks. 



The frudlifications refemble little flat pods, about 

 half an inch long, of a narrow elliptic form, 

 having a point or beak at the extremity \ 

 crrowing alternate on fhort peduncles out of 

 the edges of the ftalk and branches, but moft 

 numerous near their fummits. 



Thefe pods, on the outfuie, are tranfverfely fur- 

 row'd, iviihin, full of a vifcid liquor, contain- 

 ing feminal veficles, parted by tranfverfe Sep!a 

 or Diaphragms. 



The plant is alfo furnilhed with alternate lanceo- 

 late leaves, much longer and narrower than the 

 pods. But the pods are in reality no other 

 than thefe leaves in a ftate of fructification, fo
