of the Recent Flora of Britain . 
Pinus Abies, Linn. 
Cones. Preglacial (Cromer Forest-bed), abundant. Un- 
known in later deposits in Britain. 
MONOCOTYLEDONS. 
J UNCUS, sp. 
Fruit of rushes are abundant, but I cannot obtain any 
specimens in a determinable state. Some from Redhall and 
Hailes apparently belong to J. glaucus. 
Sparganium ramosum, Curtis. 
Fruit. Postglacial, Garvel Park — two very small and 
doubtful specimens received from Mr. Scott. Interglacial, 
Redhall — very abundant, but small. Preglacial (Cromer 
P'orest-bed) — abundant at Pakefield, very rare elsewhere. 
Alisma plantago, Linn. 
Fruit. Interglacial, Cowden Glen. Preglacial (Cromer 
Forest-bed), common at various localities. 
POTAMOGETON RUFESCENS, Schrad. 
Drupe. Postglacial, Hoxne (Ridley and Reid.) 
POTAMOGETON HETEROPHYLLUS, Schreb. 
Drupes. Interglacial, Hailes. Preglacial (Cromer Forest- 
bed), abundant at most localities. 
POTAMOGETON LUCENS, Linn. 
Drupes. Preglacial (Cromer Forest-bed), on the foreshore 
between Cromer and Runton. This species and P. praetongus 
have only been found at this one locality in the Forest-bed, 
the other four preglacial forms are abundant nearly everywhere. 
POTAMOGETON PRAELONGUS, Wulf. 
Three drupes. Preglacial (Cromer Forest-bed, between 
Cromer and Runton).
