several by which the Park can be entered. Mr. H.C. Watson, in his 
‘Cybele,’ states that this species may, perhaps, have been passed 
over as P. arenarium ; and it would be worth while carefully to exa- 
mine any alleged inland localities for the latter, on the chance of find- 
ing P. asperum with it or instead of it.”—Jd. 
On the Yorkshire Locality for Anacharis alsinastrwm, Bab. 
“Perhaps it may be worth while to note, to prevent any chance of 
misapprehension, that the Yorkshire station for this plant mentioned 
in last month’s ‘ Phytologist’ (v. 55), viz., a pond below the bridge 
over the Wiske at Kirby Wiske, near Thirsk, is precisely the same 
that was recorded Phytol. iv. 365; and that in Phytol. iv. 721, I 
explained when and in what manner it had been introduced. At my 
last visit, about three months ago, it seemed scarcely to have spread 
beyond the limits of the pond in which it was originally planted.”—

A Supplement to the ‘ Flora of Yorkshire. 
“ A Supplement to Baines’s ‘ Flora of Yorkshire’ is in preparation, 
and will most likely be ready for publication in the course of a few 
weeks. Any information relative to the rarer plants of the county, 
especially if they are not included in the original work or the ‘ Cybele 
Britannica, will be thankfully received, by either Mr. Baines or 
myself.” —Id.

The President made the following communication :— 
“ T have much pleasure in being able to add this little fern to the 
British Flora. It has just been discovered, in some abundance, by 
Mr. George Wolsey, in the Island of Guernsey. It occurs, amid short 
and very level herbage sloping towards the South, on the summit of 
rocks on the South coast of the Island, and not far from Petit Bot 
Bay. On this elevated down are a few scattered and stunted furze- 
bushes, and around these the grass is, as usual, somewhat longer ; 
and here the little adder’s-tongue is not quite so minute as on the 
level turf, where it scarcely attains an inch in length. It grows in 
company with Trichonema Columne and Scilla autumnalis, and on 
the 17th of January was in full fruit. The very early fructification, 
and the minute size, of this species will readily account for its not 
having been previously observed; and may also suggest the poss¢be- 
lity of its existing undiscovered in similar situations on the sea-coast
