57 
segments on the mud. — J. E. Lousley. Correctly named and 
accompanied by a most useful note of habitat conditions. 
I agree with Mr. Lousley that the flowers are unusually small, 
but they are at the apex of the stem and the latest produced. 
Below them are large heads of well-formed heterophyllus 
fruits. The flowers which preceded these must have been much 
larger than those now showing, and have been produced 
earlier when there was more water in the ‘ pool. — W. H. 
Pearsall. 
From the specimen before me, I should have thought this 
is a Drouetii form, but probably Mr. Lousley has followed 
its past history. In collecting aquatic plants, so liable to 
modification by external conditions, it is important to note 
as Mr. Lousley has done, any abnormal circumstance which 
may account for their peculiarities. Observation in the 
field is essential in such cases. — J. Groves. 
Ranunculus Baudotii Godr. Pool near sea, Clymping, West 
Sussex, June 9, 1930. [Ref. B 48]. — J. E. Lousley. Not 
R. Baudotii. “ No other British species has such a large 
elongate receptacle upon which grow so many glabrous 
carpels.” In B 48 the receptacle is small and round, with 
few fruits which are densely hairy at the top of the dorsal 
margin. Moreover the stem is too slender, the submerged 
leaves too small, for R. Baudotii. There are no flowers, but I 
should refer the plant to R. trichophyllus Chaix. — W. H. 
Pearsall. I should label this R. Godronii Gren. which Mr. 
Pearsall, in his admirable monograph, The British Batrachia, 
places under R. radians , but which I had thought nearer to 
R. Drouetii. — J. Groves. 
Ranunculus Baudotii Godr. Brackish pool near Newhaven. 
East Sussex, August 10, 1930. [Ref. B 58]. — J. E. Lousley. 
Yes. These specimens possess the characters lacking in B 48, 
— W. H. Pearsall. The carpels are hairy. I should call it 
R. heterophyllus var. submersus. — J. Groves. 
Ranunculus auricom.us L. Whyteleafe, Caterham Valley, 
Surrey ; roots March 23 and April 13, flowers May 11, 1930. — - 
J. Fraser. Yes ; it comes under var. reniformis Kittel. — - 
E. Drabble. 
Nasturtium . sylvestre R. Br. Blagdon Reservoir, N. Somerset, 
July 17, 1930. Has of recent years become one of the dominant 
plants there. — H, S. Thompson.
