of the Recent Flora of Britain. 
Sambucus nigra, Linn. 
Several seeds from each locality. Postglacial, Southampton 
Docks, from peat below the sea-level (Mr. Whitaker). Post- 
glacial, Tilbury Docks, from similar beds (Mr. Spurrell). 
Interglacial, Redhall, near Edinburgh (Mr. Bennie). 
Valeriana officinalis, Linn. 
Nine detached fruits, all rather smaller than my recent 
specimens, but otherwise indistinguishable. Interglacial, 
Redhall. 
Eupatorium cannabinum, Linn. 
Detached fruits. Postglacial, Tilbury Docks (Mr. Spurrell). 
Bidens cernua, Linn. 
Fruits abundant but small. Interglacial, Redhall, near Edin- 
burgh. 
Bidens tripartita, Linn. 
Fruits very rare. Preglacial (Cromer Forest-bed), Mundesley 
and Kessingland. 
Matricaria inodora, Linn. 
Thirteen well-preserved fruits. Interglacial, Redhall. 
Senecio sylvaticus, Linn. 
Six fruits. Interglacial, Redhall. 
Carduus lanceolatus, Linn. 
Several fruits. Interglacial, Redhall. Some thistle seeds 
from the Cromer Forest-bed perhaps also belong to this 
species. From both horizons the fruit are rather small for C. 
lanceolatus . 
Carduus, sp. 
One fruit from Redhall has a conspicuous collar, and ap- 
parently belongs to another species. It does not satisfactorily 
agree with any with which it has been compared, but seems 
nearest to C. palustris. 
Lapsana communis, Linn. 
Three well-preserved fruits. Interglacial, Redhall.
