Rare Plant Register for Huntingdonshire - Botanical Society of the ...

The current accounts of charophyte (stonewort) species draws heavily upon the important
baseline survey data collected by Nick Stewart (Stewart, 1999). I have not yet had the
opportunity to investigate other data sources and more recent records may be available.
I am grateful to Nick Millar for his comments on an earlier draft of the RPR and for providing
me with a copy of additional records held by the Wildlife Trust for Bedfordshire,
Cambridgeshire and Northamptonshire.
