Of the flowering plants and ferns 25 were noted in the water 
area, 98 in the marsh and 211 on the higher ground, while the 
mosses and hepatics in the same areas numbered respectively 
5, 28 and 15. Allowing for 15 species which are noted as 
occurring both on the marsh and the higher ground, it will 
be found that the number of the former was 319 and of the 
latter 48, a total of 367 species. 
Taking the marsh and water area only, the number of 
flowering plants was 123. It is interesting to compare this 
with the area preserved as far as possible in its primitive 
state, and known as Wicken Fen. In his ‘ Flora of 
Cambridgeshire ’ (i860), Professor Babington gave a list of 
plants recently found there. From this it appears that 125 
species had been found at Wicken, of which we have noted 
61 on Flordon Common. At Wicken it may be interesting 
to observe that the plant which forms the great mass of the 
herbage is Cladium Mariscus, and those which most abound 
are Thalictrum flavum, Viola stagnina, Peucedanum palustre, 
Valeriana dioica, Cnicus pratensis , Orchis incarnata, Iris 
Pseudacorus , Luzula multi flora, Schcenus nigricans, Agrostis 
canina, and Lastrea Thelypteris. Of these only Valeriana, 
Orchis , Iris and Schcenus occur at Flordon.
