of the Recent Flora of Britain. 185 
Ranunculus aquatilis, Linn. 
Very abundant in most lacustrine deposits. Several 
varieties are found fossil, but the characters of the fruit in the 
recent forms do not seem to be sufficiently constant to allow of 
any determination of sub-species from fruit alone. Horizons — 
Cromer Forest-bed, passim ; Scotch interglacial beds, passim. 
Ranunculus sceleratus, Linn. 
Two detached carpels from Hoxne in Suffolk, in a lacustrine 
deposit overlying boulder-clay, were found by Mr. Ridley 
and myself. Unknown elsewhere fossil. 
Ranunculus flammula, Linn. 
Mr. Bennie has sent me numerous carpels from Redhall and 
Hailes quarries, and one badly-preserved specimen from 
Cowden Glen. Badly-preserved fruits, apparently belonging 
to this species, also occur in more modern peats. Horizons — • 
postglacial and interglacial (not yet found in preglacial beds). 
Ranunculus lingua, Linn. 
A few detached carpels have been found at Redhall, near 
Edinburgh, in interglacial beds. 
Ranunculus repens, Linn. 
Detached achenes. Postglacial beds of Garvel Park, on 
the Clyde, and Hoxne, in Suffolk. Interglacial beds, Redhall 
and Hailes, near Edinburgh. Preglacial, in Cromer Forest- 
bed, at nearly all localities. 
In shape and sculpture of the achenes, R. repens is so 
similar to R. bulbosus and R. acris that great care is needed 
to distinguish between them, especially when the beak is 
missing. The slight differences seem, however, to be quite 
constant, and all the specimens belong to R. repens . 
Caltha palustris. Linn. 
Seeds are not uncommon in the interglacial beds at Red- 
hall.
