962 CRYPTOGAMIA ALGIE. 



oval or oblong, not tubular as in the preceding, 

 but fiat, like the jointed leaves of the CAC- 

 TUS opuntia, Lin. and frequently producincr 

 forked and tendril- like ligaments from their fum- 

 mits, particularly at the tops of the branches. 



The feeds may be difcovered, by the help of a 

 microfcope, to be lodged in great numbers in 

 the fubftance of fome of the extreme joints, 

 appearing like grains of a fine purple powder. 



This fpecies is nearly related to the preceding, 

 but quite diftinfl. It feems alfo to be the 

 link which unites together the three Genera of 

 FUCUS, ULVA, and CONFERVA.

 We found it fparingly upon the rocks of the 



Little IJles of Jura. VII. 

 This is nearly allied to the 39th, but is certainly 



a diftind fpecies. 

 The color of it is a pale or whitifh green. The 



fubftance membranaceous. The height about 



five inches. 

 Several ftalks arife from one root, each of which 



is about the fize of a fmall goofe-quill, tubular, 



nearly equal, or fo obfcurely jointed as to be
