leaves only, and originally numbered 2632, and from the same 
ditch, Mr. Pearsall wrote, “ I should include this with 2631.” 
And of a sheet numbered 2632 Mr. Pugsley wrote, “ The sheet 
seems identical with No. 2631.” Some of 2631 and 2632 were 
obviously not completely homogeneous sets. — H. S. T. The 
sheet 2631 sent shows a branched plant with the leaves linear 
and notched, except those of the terminal rosettes, which are 
broadly spathulate. The fruits are like those of C. obtusangula 
Le Gall. Rouy (FI. France, xii, 185) remarks that the lower 
leaves of this species are sometimes linear. As the plant 
appears to grow with normal C. obtusangula and perhaps C. 
truncata, it is possibly of hybrid origin rather than a form of C. 
obtusangula ; or the second parent may be C. intermedia , as 
was suggested for C. Lachii Warren, which was found in 
Cheshire and seems to be a somewhat similar plant. — H. W. 
Pugsley. 
Callitriche obtusangula Le Gall. [2633]. Roadside ditch, 
Sharpham Peatmoor, Somerset, v.c. 6, June 26, 1931. — - 
H. S. Thompson. Yes ; possibly with some slight admixture, 
almost inseparable from this genus. — W. H. Pearsall. The 
sheet received seems correctly named. The specimens have 
apparently come from the same station as those sent last year. 
— H. W. Pugsley. 
Callitriche obtusangula, Le Gall. Fridge, near Tunbridge 
Wells, Sussex, May 31, 1931 . — H. W. Pugsley and H. C. P. 
Epilobium parviflorum x tetragonum ? [2641], By dock, 
Hotwells, Bristol, v.c. 34, Aug. 3, 1931. — H. S. Thompson. 
Of the three specimens seen originally by Dr. Drabble, two 
were correctly named and the third was tetragonum. — H. S. T. 
A sheet sent to Mr. Little was found by him and Dr. Drabble 
to be narrow-leaved parviflorum only (stigma fully lobecl). 
Epilobium montanum L. fl. albo. [C 34], Nant Ffrancon, 
Carnarvonshire, June 29, 1931. — J. E. Lousley. I have never 
before seen so extensive a colour-form of this. For about a 
mile and a half along the road from Ty-gwyn to Tyn-y-meas 
1 met with only the white form. Then colonies of white and 
coloured plants occurred, finally giving place to all coloured. 
When gathered these flowers were pure white with no trace of 
colour ; in the press a few developed traces of colour. — J. E. 
Lousley. Yes ; my specimen shows some purple colour in the
