Nov. 21. READ the following “ Notice of the discovery of Cucubalus bacci- 
Jer, L., in the Isle of Dogs.” By Mr. George Luxford, A.L.S. 
“ The accompanying specimen of Cucubalus baccifer was, with 
many others, collected by me in the Isle of Dogs in the early part of 
last August. This plant was originally introduced into the British 
Flora by Dillenius in the third edition of Ray’s Synopsis. He there 
speaks of it as having been gathered in hedges in Anglesea (Mona) 
by Mr. Foulkes of Llanbedu, and sent by him to Dr. Richardson;

necessity, however unwillingly, of excluding the Cucubalus baccifer 
from our British Flora.“ It was accordingly omitted when Sir James 
published his * English Flora,’ 
* 'The locality in the Isle of Dogs is on the banks of the ditch on 
the left hand of the road from Blackwall to the Ferry House; and 
there, if not truly indigenous, it is at least perfectly naturalized. Ialso 
feel convinced that I have met with it in similar situations in other 
parts of England; but the plant not being in flower, I have passed 
it, as I did the first time I saw it in the Isle of Dogs, thinking it to 
be merely Cerastium aquaticum. It is probable that, like Polygonum 
dumetorum, this plant only requires to have the attention of botanists
