23/12/2012	tom humphrey	Deleted note: Recorded on Manchester Herb label as Titchfield Common, Hants, which does not exist but Litchfield Common does, and it could be this looking at original 1843 label. THE ABOVE IS WRONG. Titchfield Common does exist at SU5206 and is is VC11 as stated on the label. It is also on acid soil where Potamogeton polygonifolius is common. Conversely Litchfield Common is in the wrong vice county, VC12, and is on chalk where P. polygonifolius could not grow (the nearest site ever recorded is 30km away)

N.B. reporting of the edit history is currently fairly unclear and misleading. Most edits made to specimens appear as a pair of 'add' and 'delete' entries, which may not be together in the list. There are also often 'minor' edits, which are made automatically (rather than due to user activity), for example to merge synonym names.

The site needs changing to Titchfield Common in VC11 to agree with the specimen. See notes above. An inferred grid reference is SU5206 (though I would prefer tetrad level, so SU50I)
