68 Origin of the British Flora. 



The deposits described are apparently of Interglacial 

 date. Like those of Lauenburg and KHnge, they yield 

 seeds of Brasenia purpurea^ a plant which has not yet been 

 found fossil in Britain. Its recent range is very wide, 

 though it does not include any part of Europe. 



Nuphar luteum. Ceratophyllum submersum. 



Nymphaea alba. demersum. 



Brasenia purpurea. Taxus baccata. 



Tilia platyphyllos. Pinus sylvestris. 



Acer campestre. Picea excelsa. 



Vaccinium uliginosum. Stratiotes aloides. 



Oxycoccus. Typha. 



Fraxinus. Potamogeton natans. 



Menyanthes trifoliata. Najas major. 



Myrica Gale. Scirpus lacustris. 



Betula. sp. 



Alnus. Eriophorum vaginatum. 



Quercus sessiliflora. angustifolium (?). 



Corylus Avellana. Carex echinata. 



Fagus sylvatica. Goodenoughii (i*). 



Salix aurita. Phragmites communis. 

 cinerea. Aira caespitosa (?). 



Faskine, Lanark. 



(Bennie, * On the occurrence of Peat with Arctic Plants 

 in Boulder Clay at Faskine, near Airdrie, Lanarkshire,' 

 Trans, Geol. Soc. Glasgow, Vol. X., pp. 148-152. 1895.) 



The Boulder Clay here contains masses of transported 

 peat full of moss and leaves of Arctic willows. Though 

 here provisionally classed as Interglacial, they may per- 

 haps be of the same date as the Late Glacial deposits of 

 Hailes and Corstorphine. 



Viola palustris. Salix herbacea. 



Stellaria. Sedges — 3 or 4 species. 



Potentilla (.''). Isoetes lacustris. 

 Hippuris vulgaris.
