Carda ama which is recorded in Top. Bot. ed.2, but not in the Flora, was found some years ago in very small quantity close to the railway bridge over the Cam at Barnwell. Recent search there has been in vain. The rarity of this plant is quite extraordinary; it is common in the fenland of W. Suffolk, by the R. Lark. West,1898,249. 46
