8o Origin of the British Flora. 



Phys. Soc, Edinburgh, 1885, pp. 451-459; Craig, 'On the 

 Post-Pliocene Beds of the Irvine Valley, Kilmaurs, and 

 Dreghorn Districts,' Trans. Geol. Soc. Glasgow, 1887, 

 pp. 213-226.) 



The deposits occur beneath Boulder Clay, they yield 

 remains of Mammoth and of the following species of 

 plants : — 



Ranunculus aquatilis. *Potamogeton Zizii or 

 Potentilla (?). heterophyllus. 



Hippuris vulgaris. Zannichellia palustris. 



Myriophyllum spicatum. Chara. 



*Potamogeton rufescens (?). Isoetes lacustris. 



Kirk Michael, Isle of Man. 



(Lamplugh, Annual Rep. Geol. Survey for 1895, p. 13.) 



The plants occur in a peaty layer at a depth of 1 5 feet. 

 They probably belong to the same period as the upper beds 

 at Ballaugh, and the Arctic plant-beds near Edinburgh. 



Ranunculus aquatilis. Salix herbacea. 



Viola palustris. Potamogeton. 



Potentilla Comarum. Eleocharis palustris. 



Hippuris vulgaris. fCarex alpina. 



Menyanthes trifoliata. sp. 



KiRMiNGTON, North Lincolnshire. 



(Reid, 'Geology of Holderness,' pp. 58, 59,69, 70, Mem. 

 Geol. Surrey. 1885.) 



Estuarine warp, peat, and shingle occur at a height of 

 about 80 feet above the sea. The peat is a mass of the 

 common Reed, among which I could find no other plants. 

 The warp contained : — 



Scirpus fluitans. Phragmites communis.
