A 
THE PRE-GLACIAL FLORA OF BRITAIN. 209 
collection of recent seeds is steadily growing, but there are still too many 
species of which we have been unable to obtain ripe fruits ourselves, or to 
find perfectly ripe fruits in the herbaria. Until, also, we can obtain a more 
complete series of Palearctic plants, it will be impossible to say whether 
some of the various undetermined seeds belong to living or to extinct species ; 
we have decided therefore not at present to describe any species as new, 
though in all probability two or three are no longer living. 
The plant-remains from the pre-Glacial deposits of the Norfolk and Suffolk 
coasts belong to the following species :—
