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 

 10 per cent. ; but in the absence of good collections of ripe 

 seeds their determination is very difficult.
