178 THE FAUNA AND FLORA OF FLORDON COMMON. 
but a few of the larger ones have an abundance of Utricularia 
vulgaris and U. minor.* On the western common there is 
a ditch full of rank vegetation in summer. Among specimens 
of Apium nodiflorum, Sium erection, Sparganium erectum, 
Lemna minor, Glyceria fluitans and Glyceria aquatica, float 
thousands of plants of Ricciocarpus natans. This interesting 
hepatic was recorded from Heydon by Mr. Bryant in the 
18th century, and from Sutton by Mr. W. A. Nicholson in 
1906. At Flordon it was noted in the autumn of 1908, and 
since then has been found at Booton, Weston, and Little 
Melton, where in 1909, 300 square yards of water in two 
clay pits were closely covered with it. The Census Catalogue 
of British Hepatics (1905) records it for 8 vice-counties out 
of Watson’s 112, and 6 Irish vice-counties. Macvicar does 
not record it for Scotland.
