“ Rannncidus cunfiisus, Godr.” East eud of Duddiiigston Loch, 
near Edinburgh, July 6, 1876. This is a locality specified in Syme, 
‘ E. B.’ My sj)ecimens are not so good as I could have wished, 
but are the best 1 could find. The plant is confined to one end of 
the Loch, growing amongst the rharginal vegetation in shallow 
water. I could see no sign of it where the water was more than a 
few inches deep, and there were no fragments of the plant amongst 
the broken Mijrwphijllum, Pvtamoyeton, &c., that had floated to the 
edge of the Loch. — F. M. Webb. The following note was sent 
with this to the Curator by Mr. Baker : “ Mr. Hiern thinks this 
better called IJaudutii than confuam." I have no doubt that this is 
really it. cunfusus, Gren. & Godr. I sent specimens of it to the 
late Professor Grenier under this name, and he returned an answer 
that they were correctly named, according to his judgment. 
J{. cun/Hsus I believe to be the fresh-Avater form of E. Baudotii . — 
T. B. Boswell. The Duddingston Loch plant is Baudotii, as Mr. 
Hiern thinks. — C. C. Babington. 
“ ii. Baudotii, Godron, v. cunfusus?" Pool in Old Town bog, 
St. Mary’s, Scilly, May, 1876. Collected by Mr. CurnoAV for Mrs. 
Lomax. This I should call a form of R. peltatus ; it has neither the 
conical receptacle nor the ligulate stigma of R. cunfusus, and 
indeed differs from R. tnincatus only in its nearly glabrous carpels. 
— J. T. Boswell. The Scilly plant, I think, is also Baudotii. — C. 
C. Babington. 
R. salsuyinusus. Tweed, near Kelso, Eoxburgh, July, 1875. 
This form is frequent in the T^veed. — Andrew Brotherston. To 
tliis note of Mr. Brotherston’ s Dr. Boswell appended the following : 
“I don’t know what to call this; it is not salsuyinusus, which 
is R. con/usns Avithout floating leaves. It reminds me of a plant 
from Plertfordshire, sent by Mr. T. B. BIoav.” Probably correct 
according to Hiern’s nomenclature, but a state of confusus. — C. C. 
Babington. 
R. salsuyinusus ? In the Chester and Ellesmere Canal, near 
Cristleton Bridge crossing it/ S.E. of Chester. Collected in 
company AAuth Mr. Webb, June 29, 1875. A great mass of this 
batrachian fringes the canal, and at this point and once else in the 
neighbourhood of Cliester we found floating leaves. I submitted 
the plant to Mr. Hiern this autumn, and he writes me that “ it is 
the same, or very nearly so, as the North Devon specimens alluded 
to by me in ‘ journ. Bot.,’ ix., p. 103, under No. 31 (1871.)” 
Turning to No. 34 [R. marinus) of Mr. Hiern’s monograph, Ave 
read : “A curious state best referred to this form (i.<?., R. marinus), 
occurs in England (N. Devon) and SAveden! with elongated, rather 
stout and sub-parallel leaf-segments, and small flowers with hairy 
fruit receptacles. It approaches fluitans and pseudojiuitans. The 
Devonshire plant occasionally has floating loaves, and then it 
would belong to Baudotii. It grows in a mill-stream liable to be 
mingled Avith tidal Avater.” No doubt the canal- water is some- 
Avhat brackish Avhence the specimens came, as avc saAV CaUitrichc 
ohtusanyula in theii- company. — J. L. Warren. I should call this 
R. cunfusus, Gren. & Godr. — J. T. Boswell.
