Before the feeds are ripe, the tubercles appear as rcprefcnteJ iii 

 Gmelin's figure, and have conftantly one or two furrows acrofs 

 them. They are fituated on the upper part of the frond, but not 

 on the extreme divifions, and are ufually diftant, but fometimes two 

 or three are found aggregate. 



This fpecies is readily diftinguifhed from all its affinities, by its 

 expanded leathery root — its very different mode of frudtifying — its 

 very acute terminations — and by its brighter and more tranfparent 

 purple colour, which is clearly difcernible when dry, if the plant be 

 held to a ftrong light. 



It grows on the large flones at Cromer on the coafl of Norfolk^ 

 and is found amongft other rejedamenta at Yarmouth and other 

 places to the fouthward.
