sight of, and the interest in it died away until the Autumn 
of 1847, when it was again discovered by Miss Kirpy, of 
Lubbenham Lodge, in reservoirs adjoining the Foxton Locks, 
on the Canal near Market Harborough, in Leicestershire. 
The plants were all females, and were found in considerable 
abundance, growing “ closely matted together.” Miss Kirpy 
had not observed it there before, and the reservoirs had been 
cleaned out two years previously. 
Miss Kirpy’s rediscovery awakened the attention of 
Botanists to the subject, and Mr. BaBincron published a 
description of the plant in the “ Annals of Natural History,” 
for February, 1848. Dr. Jounsron, the first discoverer, on 
reading Mr. Banineron’s account, at once recognized it as 
the plant he had found in the Loch of Dunse Castle, and in 
the following Autumn found the plant in two stations in the 
Whiteadder River. 
_. The same season, but later, it was found by Mr. JAmEs 
MiTcHEL, in Nottinghamshire, in the Lene, (a tributary of 
the Trent) near Nottingham, “ growing in great profusion 
for about a quarter of a mile in extent.” In November, of 
the same year, it was found in Northamptonshire, in the 
Watford Locks, by Mr. Kirn, “ very abundant.” The 
Watford Locks are on the same line of Canal as the Foxton 
reservoirs. Mr, Kirx observed that when water was drawn 
from either of the Locks, the force of the current detached 
small sprigs of the Anacharis, which were carried into the 
body of the Canal. Mr. Krrx considered it to be an intro- 
_ duced plant. His plants were also all females. Subsequently, 
Mr. Kirk changed his views, and regarded the plant, “ from 
its simultaneous discovery in so many other localities,” as a 
true native. He also described it as growing in such dense 
masses, that it was with difficulty good sized specimens could 
be detached, owing to its extreme brittleness. Mr. Kirk 
was informed by the Lock-man that the plant was quite as
