192 BRITISH SEA- WEEDS. \Rhodospermecf: . 



a specimen got by Mr. Yalclen in the Pritli of Tortli ; it is, 

 therefore, not a little strange that it has not been found in 

 any part of ScotLand since. 



2. Griffithsia simplicifilum, Agarclk. 



This is like the preceding, but a more elegant plant. Its 

 branches are attenuated to a sharp point, and it keeps its 

 fine colour in drying. Coast of Norfolk, Eev. W. S. Hore, 

 from whom I have a beautiful specimen. 



3. Griffithsia Devoniensis, Harvey. 



"\Thile I refer for the figure of it to Phyc. Brit., PI. xvi., 

 I have great pleasure in quoting the following from that 

 work : — 



" This graceful little plant, which appears different from 

 all the species of Griffithsia yet described, was discovered in 

 the summer of 1840 by the Rev. Mr. Hore, at Plymouth ; 

 and in the autumn of the same year, added to the flora of 

 Devonshire, by Mrs. Wyatt. I record this latter habitat in 

 the specific name, because it affords me an opportunity, of 

 which I avail myself, to connect the name of Mrs. Griffiths 

 with that of the county wdiose shores she has so long and 

 so successfully explored, where the best part of her life has 

 been spent, and the natural history of ^hich, in all its 

 varied branches, her researches have so greatly advanced.'^
