CAREX AQUATILIS Wahlb. IN LAKE 
LANCASHIRE. 
ARTHUR BENNETT, F.L.S. 
Croydon, Surrey. 
Amonc a large parcel of Irish plants sent me by Mr. Praeger were 
two British from Lake Lancashire, ‘Windermere, 1895, R. Lloyd 
Praeger,’ both of which are additions to Mr. Baker’s Flora of the 
English Lake District, 1885, one being Ca/amagrostis lanceolata Roth., 
the record of this not having been confirmed (I have specimens 
gathered at Dufton, Westmorland, by Prof. Oliver) as occurring at 
rea Lonsdale. 
r. Praeger has kindly furnished me with the following note on 
the facies for the two species :—‘ Edge of Blelham Beck, Winder- 
mere, Lancashire. The stream flows from Blelham Tarn into 
Windermere, debouching at the Ambleside end, half-a-mile south of 
the mouth of the River Brathy. If you row up the stream you will 
find Carex aguatilis growing on the north bank, a short distance 
from the mouth. Ca/amagrostis grows on the south bank a little 
further up. The sedge was found by Miss Knowles and myself; 
the grass by me. Date August 8th, 1895.) The ground imme- 
diately around the Tarn is about 500 ft. above ‘sea-level,’ the depth 
of the Tarn is given at 138 ft. in the Bathymetrical Survey of the 
English Lakes by H. R. Mill (Geographical Journal, July and 
August, 1895). The Tarn is fed by small streams, and also connected 
with a smaller Tarn near ‘ Randy Pike.’ The highest land which 
seems to drain into the Tarn is about 1,000 ft. from Claife Heights. 
The other, Carex aguatilis Wahlb., is the lowland form. 
Mr. Baker notes under L. Lancashire, ‘In the Whitehaven Cata- 
logue, C. aguatilis Wahlb. is reported from St. Bees, but no doubt 
the name is incorrect, as it is a high-mountain speciés,’ p. 221. 
At the time this was written no one would have thought of 
accepting such a plant without specimens, for 25 years before this 
we find it even doubted whether we really had Wahlenberg’s species 
in Britain (see Hooker and Amott, Brit. FL, ed. 8, p. 508, 1860), and 
by so good an authority on the genus as Dr. Boott. 
Its occurrence in Wales (about 52° 15”) was to some extent 
a surprise, but still more so when it was found to be an Irish plant, 
and so far south as Kerry. It seems a very interesting case of 
distribution when we come to look at its European range ; I know 
of no station south of Livonia and Ingria (St. Petersburg) in Russia, 
and this cannot be under 57° N. Lat. We may call Kerry 52° ; but 
March 1897.
