thefe leaves are proliferous, having others more minute growing : 
from their fides. 
The fruétification confifts of minute feffile tubercles, numerous, 
but placed without order on the lower part of the principal 
branches, and fometimes, but rarely, on the leaves; dark red, fo 
{mall as {carcely to be diftinguifhed by the naked eye, unlefs the 
plant be moiftened, but eafily difcernible with a common eye- 
| glafs. 
The whole plant has fomewhat of a granulated appearance, 
which, added to the gelatinous nature of the frons, has occafion- 
ed it to be fuppofed an Ulva; but this appearance is fallaci- 
ous, the granulations under the microfcope proving to be no- 
thing more than the fubftance of the frons, in this refpect 
agreeing. with Fucus rubens, which fubmitted to the fame exami- 
nation has a fimilar appearance. 
This A/ga was firft found a few years fince, wafhed up by the 
tide at Yarmouth, by Mr. L. Wigg, an affociate of this Society ; 
and was then pronounced, by a highly refpectable botanift, to be 
the Ulva, filiformis of Hudfon ; but it does not accord with the Ípe- 
cific chara&er of that plant in the Flora Anglica, and whether 
it be at all defcribed in that work feems very doubtful At any 
rate the fructification, confifting of diftin& tubercles + 
projecting from the fubftance of the frons, fufficiently pont it out 
to be a Fucus. E | 
.. Its place in the Syftem is next to Fucus valis (Fl. Ang.), which, 
in the fubftance of the frons, and form and difpofition of the 
. leaves, it confiderably refembles, confequently in the fubdivifion, 
* fokis diflinétis ? but as it is evident that both thefe plants have 
feiby leaves, not differing in fubftance from the reft of the frons, 
they
