This often varies on the same plant. In M. alterniflorum it 
may be 3 or 4, in M. spicatum more usually 4 (but may be 
3 or 5 on occasion) and in M. verticillatum it is more often 5 
than fewer. I trust Mr. Thompson will be able to gather this 
again in a flowering condition.— W. H. Pearsall. Of a Blagdon 
Lake specimen, Sept 5, 1933, Mr. Fraser says it seems right 
for M . spicatum ; but an inflorescence would have settled the 
matter. I could find or reach only one flowering spike at 
both Reservoirs.- — H. S. T. 
Callitriche [stagnalis Scop. ? var. platycarpa Kuetz.]. Chew 
Magna Reservoir, N. Somerset, Oct., 1933. Some of it in 
large prostrate patches on the mud. — H. S. Thompson. 
Hegelmaier in his Monograph insists that ripe fruit is essential 
for the correct determination of species in this genus, and the 
late Arthur Bennett often declared that without fruits it was 
‘ mere guess work.’ On my sheet there are none, but the 
leaves and habit are not those of C. stagnalis, our largest 
species. According to Kiitzing the var. platycarpa has the 
lowest leaves 11-12 mm. long “ cetera varia plurimum obovata 
16-18x5-6 mm.” The largest leaves on my sheet are only 
8x2-5 mm. In my judgment the plants are not C. stagnalis 
nor its var., but more probably C. polymorpha. I should much 
like to see mature fruits of these plants this year. — W. H. 
Pearsall. I was misguided by two somewhat similar sheets in 
my herbarium from Rotten Park Reservoir, Birmingham, 
1893, which had been named for me by the late W. R. Linton.

Callitriche truncata Guss. var. occidentalis Rouy. [Ref. 1762] 
Muddy and/or sandy bed of R. Derwent, Chipstead, W. Kent, 
v.c. 16, Aug. 26, 1933. Growing submerged in the swift 
stream and forming oval clumps. — E. C. Wallace. Excellent 
material of a rare plant, although not flowering. — H. W. 
Pugsley. The leaves of these specimens are narrowed at the 
base, widened upwards, and rounded at the apex with a small 
notch or two teeth. They are also wider than any descriptions 
and figures allow, so it may be Rouy’s variety. I fail to find 
any fruit, and these water-weeds are rather polymorphic in 
the leaves. — J. Fraser. 
Epilobium : Mr. Ash agrees to the naming of all the 
Epilobia sent him, but does not think it necessary to write a 
short ‘ yes ’ to each. He has kindly written a few notes when 
he thought there was something of interest to say. — Ed.
