Report for 1908. 
native here ; but is not there a chance of its being introduced with 
game food ? — G. C. Drucf:. 
Sparganuun neglectum, Beeby. Large pool north of Falfield, 
W. Glos., 22nd July 1908. A very puzzling plant, inasmuch as it 
has the habit and facies of 6”. neglecUun, and yet the fruit — which 
have no marked shoulders — are smaller and more numerous than 
is usual in that species. The heads might well pass for those of 
var. microcnrpum of ramosum. Mr. C. E. Salmon had mature 
fruiting specimens from one not long ago, and through them I am 
looking for Mr Beeby’s kind determination. — J. W. White. Prob- 
ably correct, but we should like to have seen a more mature 
specimen. — H. and J. Groves. 
Sagittaria heterophylla, Pursh, var, iscaua, Hiern. River F-xe, 
Exeter, Aug, 1908. See ‘Journal of Botany,’ 1908, page 273, In 
some considerable quantity, close to the Children’s playground, on the 
muddy margin of the River Exe, at hlxeter. It also grows in several 
large patches near the bridge ; but I was unable to see any in the 
river a/fove the Paper Mill. Mii/iuliis Langsdorfii also occurs in 
the stream. As to the manner of introduction into the Exe of 
this North American species, one can only, at present, conjecture. 
I found that American wood pulp has been used at the mill, and 
heard that American logs had been brought to the river at Exeter : 
whether the s6eds came with them we have no evidence. It is 
evidently not of quite recent origin, although I suspect it is a very 
rapid grower. Unfortunately at the date I gathered it no trace of 
dowering stalks were visible ; but on the principle that “ half a loaf 
is better than no bread,” I have ventured to send leaves onlv. 
These, as it will be seen, resemble AHsma Plantago-aquatica more 
than those of our native Sagittaria, and have undoubtedly misled 
the local botanists, who failed to notice this alien in their midst. 
The very succulent leaf-bases were not promising subjects for drying 
paper. — G. Claridge Druce. 
Potamageton pensylvanicus, Cham, et Schum. (wrongly spelt 
pensylvauica on labels). Canal, Salterhebble, Halifax, S. W. Yorks, 
v.-c, 63, June and July 1908. Coll. Miss A. E, Vigurs; Comm. 
C. C. Vigurs. The double sheets, showing the plant before the 
flowering and in the fruiting stage, will, I hope, give members 
a good idea of the characters of this beautiful plant ; though the 
preparation, for which I am responsible, leaves much to be desired. 
It seems to have flowered later this year than last, when there was 
good fruit by the end of June. This year my sister found a second 
patch in another part of the canal, so we hope it is spreading. The 
first report of the plant in Britain was given by Mr. A. Bennett in
