SUAEDA MARITIMA, Dum. 
Seeds corresponding exactly with this species, except that 
they are slightly smaller than my recent specimens, occur 
abundantly in the Cromer Forest-bed. They may, however, 
belong to a species of A triplex. 
Polygonum aviculare, Linn. 
Fourteen detached fruits. Interglacial, Redhall. 
Polygonum persicaria, Linn. 
Seven detached fruits. Interglacial, Redhall.

Fruit in fruiting sepals. Preglacial (Cromer Forest-bed), at 
most localities. 
Rumex obtusifolius, Linn. 
Fruit in fruiting sepals. Interglacial, Redhall. 
Rumex crispus, Linn. 
Fruit in fruiting sepals, and detached nuts. Postglacial 
(Clyde beds), Garvel Park (Mr. Scott). Interglacial, Redhall. 
Preglacial (Cromer Forest-bed), Sidestrand. The Forest-bed 
specimen was accidentally destroyed before properly compared 
with the recent forms. 
Rumex acetosella, Linn. 
A single well-preserved fruit. Preglacial (Cromer Forest- 
bed), Beeston. 
Euphorbia helioscopia, Linn. 
Eight seeds, all split lengthwise (by birds P). Interglacial 
Redhall. 
Euphorbia amygdaloides, Linn. 
Two seeds. Preglacial (Cromer Forest-bed), Mundesley.
