may be correct of the same fruits. The dorsal margins are 
sharply keeled or 4 winged.’ This character is valuable but 
is often difficult to make out. The fruits of these examples 
have an appreciable transparent 4 edge ’ to the dorsal margin. 
- — W. H. Pearsall. This is C. obtusangula Le Gall. — H. W. 
Pugsley. I now agree with Mr. Pugsley. — H. S. T. 
Callitriche truncata Guss. ? [Ref. 4324]. The same rhine 
on Sharpham Peat Moor, Somerset, v.c. 6, June 14 and 
Oct. 3, 1930. Some of the lower and practically leafless stems 
were nearly two feet in length. I regret specimens are not 
better. — H. S. Thompson. In the absence of fruits it is 
impossible to give a stable determination of these plants. 
They are obviously either C. autumnalis or the var. occiden- 
talis of C. truncata. The former is a more robust plant, with 
more numerous and much darker and longer leaves, so 
tentatively I am inclined to let the name stand. Plants from 
the same habitat, gathered earlier in the 1931 season, would 
be acceptable. — W. H. Pearsall. 
Ribes alpinum L. Valley of the Dove, near Ashbourne, 
Derbyshire, per Walter Barratt, May 18, 1910. — A. 0. Hume. 
Comm. S.L.B.I. 
Peplis Portula L. A muddy pond at 1,000 feet on the 
Mendip plateau, E. of Blackclown, Somerset North, had on 
June, 1930, a broad belt of this plant so strangely rare in 
Somerset. — H. S. Thompson. It ascends to 1,200 feet in 
Yorkshire. — J. Fraser. 
Epilobium montanum L. ? Clifton, Bristol, v.c. 34. A 
garden weed, and on wall adjoining, June 4, 1930. — H. S. 
Thompson. Yes, excellent specimens of the large-flowered 
form. — E. Drabble. Correct. — A. E. Wade. 
Epilobium tetragonum Curt. Sandy allotment ground near 
Weybridge, Surrey, July 10, 1930. [Ref. B 50]. — J. E. 
Lousley. Yes. — E. Drabble and H. W. Pugsley. 
Epilobium tetragonum Curt. Waste ground near Thames 
at Ham, Surrey, July 9, 1930. [Ref. B 54], — J. E. Lousley. 
Yes, this is very good tetragonum. The basal autumnal shoots 
ought to be present for complete representation. — E. Drabble. 
Correct. — A. E. Wade. E. tetragonum Curt., luxuriant, — 
H. W. Pugsley.
