We have never had the good fortune to fee this plant in a 

 ftate of growth ; only fragments thrown upon the fhore have come 

 to our hands. We can fpealc therefore only of the upper parts of 

 the frond ; we give the height and the fubftance from Gmelin. 



The account which Gmelin gives of its growth feems rather ex- 

 traordinary. His words are — ' The branches arifing from the main 



* ftalk produce a footftalk which bears an oblong veficle ; from this 



* veficle another footftalk proceeds, and again this footftalk is fwelled 



* with another veficle, fo that the branches make up a feries of pro- 

 ' liferous veficles.' We have an idea that Gmelin's defcription is 

 applicable to the unfolding of the frond, rather than the growth 

 itfelf ; for the leaves at the bafe of the little branches are without 

 any veficle at all — then not unfrequently after the branch has 

 proceeded to the produi^ion of a veficle, a barren leaf or two inter- 

 venes
