This fpecies, for a fpecimen of which I am indebted to Mr. Turner, is 

 nearly allied to C.Jlrifia, but the habit of the two plants is very different. 

 It is of about the fame fize, but may be diftingui filed by its more diffufe 

 growth, by its different ramification, and numerous {hort lateral ramuli. 

 The length of the joints in both fpecies is fubje£t to fome variation, but 

 thofe of C. patens are comparatively fhorter. Many of the ultimate ramuli 

 in the fpecimen now before me are fwollen, and in thefe red globules may 

 be obferved, fimilar to thofe which in feveral of the other marine algte are 

 called feeds ; but with all due deference to the opinion of my friend Mr. 

 Turner, I mull confefs that I ftill feel myfelf very doubtful of their real 

 nature. The (ketch at Plate G was made from a dried fpecimen by Mr. 

 Hooker, and reprefents different parts of C. pate/is magnified with powers 

 5, 3, and 1 of his microfcope.

The plant which I have here arranged as a variety of C. flriSla, was 

 gathered in the neighbourhood of Bantry by Mifs Hutchins, and in her 

 opinion is a diftinft fpecies. There is indeed at firft fight a ftriking difference 

 between them, but this gradually vanifhes when the two plants are compared. 

 It differs in its mode of growth, which is much more bufliy, and in its 

 general outline, which is more orbicular. The common appearance of C. 

 Jiricfa retains its gloffy red when dried, but the color of this variety then
