Native. Lacustral, 'The gradual manner in which the 
area of this little plant has been extended, and its localities 
increased in number, yields a striking illustration of the 
close attention bestowed upon British botany during the 
present century. Even so late as the date of the English 
Flora, 1824, we find its author recording only two locali- 
ties for this species, in Shropshire and Berkshire. My 
collection of localities now indicates its occurrence in Corn- 
wall (Rev. W. S. Hore), Sussex (Mr. Borrer), Surrey (Rev. 
W. H. Coleman), Berkshire (Mr. T. F. Forster), Warwick- 
shire (Dr. Lloyd), Shropshire (Rev. A. Bloxam), Angle- 
sea (Mr. C. C. Babington), Leicestershire (Mr. Churchill 
Babington), Cheshire (Dr. Wood), Perthshire (Mr. James 
Macnab), Kincardineshire (Dr. Dickie). It seems so pro — . 
bable that other stations will yet be discovered for this = 
minute plant, that I have ventured to add to the number a 
counties and provinces, in the line of estimates ; although 
I could scarce select the two provinces and four -counties | 
in which it is most likely to be discovered: South Wales 
and the Lakes seem very probable. In too many counties 
to be referred to the “local” type; yet known in too Re 
to be strictly * British.” : me
