Prickles and achenes are not uncommon at several 
localities. The achenes are always short in proportion to 
their breadth, and very small; the prickles are generally 
curved and small. I have seen nothing approaching to 
the common living forms of R. canina, L.; and the fossils 
more suggest a species with small globose fruits, 
PYRUS TORMINALIS, Ehrh. 
Interglacial :— 
Hitchin, Hertfordshire; Hoxne, Suffolk (bed D).
