I am fully convinced that the native British Oaks may all be 
referred to Quercus sessiliflora, Q. Robur (= Q. pedunculata), and 
the hybrid between these species (Q. Robur x sessiliflora). There 
is perhaps just a possibility that the South European species, 
‘ Niierecea, in one of its forms, is a native British plant. 
QY. Cerris occurs a ted tree in woods in the south of 
England, as well as in plantations and park-lands; and it some- 
times springs up from self-sown seed.
