Deposits containing Fossil Plants. 95 
limestone species all being represented by their seeds, 
Leaves, except badly preserved fragments, are not found. 
The 94 species in the subjoined list were obtained by 
Mrs. Reid and myself by washing about two hundred- 
weight of the loamy sand. Only two of those determined 
are now extinct in Britain, though among the undetermined 
seeds are several well-marked forms, which do not belong 
to any living British plants, but cannot yet be identified. 
Najas minor and N. graminea are both southern forms, 
Acer monspessulanum, so common at Selsey on the east, 
and at Stone on the west, has not yet been found at West 
Wittering. The exotic species probably number nearly 
IO per cent.; but in the absence of good collections of ripe 
seeds their determination is very difficult.
