Notes on the ‘ Cybele Britannica, Volume ITI. 
By Wituiam Boreer, Esq., F.R.S., &e. 
(THESE Notes were kindly given for my use by Mr. Borrer. And 
seeing that most of them have the valuable recommendation of being 
either additions to knowledge previously on record, or corrections of 
imperfect and erroneous records, I requested Mr. Borrer’s permission 
to forward them to the ‘ Phytologist, which he has allowed me to do.

10. Potamogeton flabellatus. Add to the enumeration of counties 
Warwick. Mr. Kirk found it at Coventry, and was the 
first to point out its difference from the true P. zosteraceus, 
Fries. 
14. Potamogeton zosterifolius. I have never seen a Sussex spe- 
cimen. It is by mistake, no doubt, that it is said to grow at 
Henfield. 
18. Potamogeton heterophyllus and (p. 22) P. plantagineus. In 
the ‘ Phytologist’ for 1852 (iv. 637) these two species are 
said to occur on the ridge of Tilgate Forest, about a mile 
South of Balcombe. Having never before heard of the for- 
mer as a Sussex plant, and suspecting that the Sussex spe- 
cimens that have been named P. plantagineus belonged, in 
fact, to P. oblongus; I applied to one of the writers of the 
memoir referred to for specimens of the plant, or directions 
to the spot producing them; but received no answer. I 
must, therefore, still hesitate to regard them as natives of the 
county. 
84. Eriophorum latifolium. Whatever the E. polystachion of 
Dartmoor may be, this is a native of Devon. It grows in the 
deep valley on the right of the ascent of Haldon, in the way 
from Exeter to Chudleigh: W. B. 
85. Eriophorum gracile. Myr. Woods’s specimens, of which I 
possess one, prove his Yorkshire plant to be this species. 
Hagnaby, in the ‘ Manual,’ is no doubt an error of the pen or 
of the press. The Sussex plant, as well as Don’s from the 
Highlands of Scotland, has long since been ascertained to be 
a slender variety of E. angustifolium, Roth, E. polystachion, 
Linn.
