Deposits containing Fossil Pla^its. 71 



Grays, Essex. 

 (Tylor, ' On Quarternary Gravels/ Quart. Journ. Geol. 

 Soc, Vol. XXV., p. d>2>. 1869 ; Reid, ' Pleistocene Plants 

 from Casewick, Shacklewell, and Grays,' ibid. Vol. LIII., 

 p. 464. 189;.) 



The plants collected by Prestwich occur associated with 

 or below the remains of Mammoth and Corbicula fluminalis. 

 They point distinctly to a temperate climate and mild 

 winters, for the Ivy is extremely sensitive to winter cold. 

 Both the character of the flora and the position of the 

 deposit suggest correlation with the temperate plant-beds 

 of Hoxne, which lie between the Boulder Clay and the 

 deposit with Arctic species.

Rubus fruticosus. Salix sp. 



Rosa. Potamogeton. 



Hedera Helix. Cyperus (?). 



Ulmus (?). Phragmites (.?).

Greenock (Roxburgh St.). 



From the Clyde Beds (Late Glacial or Neolithic) 



Mr. Thomas Scott obtained the following species : — 



Potentilla Tormentilla (i*). Carex. 



Taraxacum officinale. *Anthoxanthum odoratum. 



Thymus Serpyllum. *Poa trivialis. 



Atriplex patula. 



Grunenthal, Holstein. 



Weber, Neues Jahrb. Mineralogie, Geologie . . . . 189 1, 

 Vol. II., pp. 62-85, 228-230; and 1893, Vol. I., pp. 94-96.) 



* These I think are recent specimens ; they are not in the same 

 state of preservation as the others, and are therefore omitted in the 

 summary. It is extremely difficult to prevent the adherence of light 

 grass-seeds when removing lumps of clay.
