All these varieties are found common enough in our seas, 
except the first sort which is mentioned by Linnzus, but-I be- - 
lieve has not been found on our coast. ~~ 
The structure of the fructifications much resembles that of 
the F. serratus, and the mid-rib dies away where the granulations 
in. Pe 
Both this and the F. serratus when fully grown, are forced 
continually by the flux of the tides against the rocks, and by 
the constant collision lose the membranaceous part of their lower 
leaves, while the main stems, which are exceedingly tough, 
acquire a smooth roundish form, and the forked ribs which per- 
vade Pye leaves wear away to sharp thorny points: In 
this state both these plants have a shrub-like appearance, whilst 
the short leaves and inflated vessels at the summit of the branches 
are frequently entire. If the F. vesiculosus receive an injury of 
fracture, in any part of the leaf, provided it be in a healthy 
vegetating state, it constantly throws out abundance of young 
leaves from the injured part. If even a small aperture be made 
in the middle of it, a new leaf on either side will be found to 
shoot out. I have rarely discovered this proliferous tendency in 
the F. serratus. Major Vettey. The terminating bladders 
when broken off are also replaced by a number of smaller ones.
