CRYPTOGAMIA ALGiE. ^i,^ 



The middle ftalk is flat and linear, about one- 

 fifth of an inch wide, and continued throughout 

 from the bafe to the fummit of the plant, ending 

 acutely. 



This ftalk is doubly proliferous ; for out of the 

 edges, in a diftichous and oppofitely pinnated 

 order, grow narrow, fword-fbaped, leafy liga- 

 ments, from three to eight inches long, which 

 are again pinnated with fliorter but fimilar liga- 

 ments, ciliated on the margins with the rudi- 

 ' • ments of others, not much bigger tlian hairs. 



The primary ligaments are for the mod pare 

 gradually fhortened towards the fummit of the 

 ftalk, fo as at lafl to leave it fimply pinnated, 

 and thereby give to the plant a nearly conical 

 form. 



The fruftifications v/e have never obferv'd, but 

 fuppofe they muft refide in the minute cilia or 

 marginal ligaments.
