XIII. The Hifory i A of a new Species of Fucus, By Thomas 
Woodwatd, Efq. Fellow of the Linnean Society. 
Read April 7, 1789. 
PLANT belonging to the order of Algæ of the Crypto- 
gamia clafs of Linnæus, and fuppofed to be a non-defcript 
Fucus, has been long found in great quantities on the beach at 
Yarmouth, amongft other rejeétamenta of the fea. A fpecimen of 
this was fent fome years ago by Mr. Pitchford to the late ingenious - 
Mr. Lightfoot, whofe knowledge of this clafs of plants was un- 
doubtedly great, and whofe judgment defervedly held in the higheft 
efteem. In anfwer to Mr. Pitchford’s enquiries, Mr. Lightfoot de- 
clared that the plant was new to him, and was not, as he believed, 
defcribed in Mr. Hudfon’s Flora Anglica, or by any author with 
which hewas acquainted; but, till it could be found in fructification, © 
nothing could be pofitively afcertained concerning it. On the ar- 
rival of the Linnean Herbarium in England, I carried a fpecimen 
to London, and compared it, along with my worthy and learned 
friend, in whofe poffeffion the Herbarium now is, with the fpe- 
cimens of Fuci there preferved; but we found none that at all cor- 
refponded with it. In this ftate it refted, it not being ever known 
from whence the plant, though fo frequent on the Yarmouth beach, 
' was wafhed ; when in the month of October, 1787, I vifited Cro- 
mer, on the north-eaft coaft of Norfolk, with a view of examining © 
whzt fea-plants grew on the rocks there; as they are called by the
