CHARACEAE {Stoneworts) Suffolk cannot claim to yield a Chara-^orz. like that of Norfolk, though a more careful and extended examination of its waters may well reveal some unsuspected treasures. Probably there are few orders of aquatics which demand a more patient and thorough search than the Characeae to secure a full yield of species. A stream which may exhibit no trace whatever of their presence at a given time may yet have been full of excellent specimens three or four weeks earlier. Again, a piece of water which seemed to be wholly destitute of Characeae at one end may prove to possess an abundant supply at the other ; whilst again a ditch or pit carefully examined for years without result may only require to be cleaned or re-dug to yield a remarkable crop the following spring. It will thus be seen that no locality can be regarded as exhaustively worked for Characeae till the examination has covered every piece of water at all times of spring and summer 69
