 This is the Largest British species of the Lamim 

 its frond ; n - >me instances forming, when Bpread out on 

 the ground, a circle twelve feel in diameter. Its common 

 name is Furbelows, and its aspect must be familiar t 

 rs of the Bea-shore.

This is a very distinct and beautiful species, and one of 

 the largest of the genus, the frond being frequently as large 

 as a moderately-sized table-cloth. It abounds along the 

 coast of North America, as far south as Boston Bay, and 

 is of particularly Large dimensions, and in great abun- 

 dance, in the deep harbour of Halifax. It would seem also. 

 from its other recorded habitats, to be generally dispersed 

 through the Arctic Sea. But what are its claims to a place 

 in the British Flora? At present they are extremely doubt- 

 ful — all the specimens which have been found being merely 

 the Btipes, covered with barnacles, and deprived of both 

 root and leaf. The hollow stipe, tapering to both ends, is 

 however so remarkable that do mistake can be made in 

 identifying the specimens. In general aspect it resembles 

 i charina, but the frond is proportionally broader and 

 more blunt, and of thinner substance ; ti hile the very long 

 stem, hollow and Bomewhat Bwollen in the middle, will 

 always afford a clear mark of distinction. Our figure is 

 taken from a characteristic specimen collected at Halifax,
