BRISTOL BOTANY IN 1915 AND 1916. 
of North Somerset. Discovered June, 1915, in a peaty pool not 
far from Meare, S., by Mrs, Sandwith. And at the end of 
the following month in a pond near Brent Knoll Station, and in 
another towards Lympsham by the same lady in company with 
Mr. C. Bucknall. On August 5, Mrs. Sandwith found it again 
in a rhine between Catcott and Shapwick, quite hidden and 
covered by masses of duckweed. It shewed itself by adhering to 
the botanist's stick. In September the plant was found once 
more by Miss Roper in a pond and rhine by the railway between 
Middle Burnham. and Edith Mead. 
Cyperus fuscus L. As stated in my paper for 1914 this sedge 
had not been seen in the Walton valley for a considerable time. 
In September last, however, a few plants of it rewarded a joint 
search made with several friends along some of the peaty ditches. 
Eriophorum latifolium Hoppe. Is now known in three dis- 
tinct spots on the western face of Blackdown. 
Carex lasiocarpa (filiformis) x ripana=C. evoluta Hartm. 
This hybrid, which had not previously been seen in Britain, was 
observed by Mr. H. S. Thompson in July, towards the eastern 
end of the peat-moor between Edington and Street. Its distri- 
bution on the Continent and synonomy are fully described by 
the discoverer in Journ. Bot. LIU., p. 309. 
C. hirta L. var. spinosa Mortensen. Gathered by Mr. H. S. 
Thompson at Charterhouse on Mendip, whence he kindly fur- 
nished me with an excellent specimen. It is a form with com- 
pound spikes and long spinescent glumes, that appears to have 
been ignored by most writers on the genus who possibly deem 
it of little importance. 
Spartina Townsendii H. and J. Groves. The Proceedings of 
the Bournemouth Nat. Science Society contain instructive records 
of the spread of this grass along the tidal shores and inlets of 
Poole Harbour. These are the result of five years' labour by 
our former member, Mr. R. Vowell Sherring, F.L.S., who has 
long occupied himself with observations on the rapid and ex- 
tensive progress of this grass. Many mud-flats have now become 
thickly covered and converted into meadows of succulent fodder, 
for which cattle have a great liking. We may anticipate a 
like change among the mud-flats of North Somerset, as the Rev. 
E. Ellman reports the interesting fact that he has seen the 
Spartina being planted (in 19 13 to begin with) on the foreshore 
between Clevedon and Woodspring with the evident object of 
binding the mud and solidifying it against inroads of the tides. 
C alama.gr ostis epigeios Roth. Highwood Lane, Oyer, G., 
F. Samson. Plentiful for many yards north of the old canal 
and railway between Meare and Shapwick Station, S. Ine 
specimens so closely resembled C. lanceolata in their loose, open 
panicles that it was only by dissecting flowers that determina- 
tion became definite.
