SOME RECENT AND FOSSIL FAGACEA. 439 
Kräusel (1919) describes Fagus leaf-impressions from the Tertiary of 
Silesia, and considers that F. sylvatica and F. ferruginea both occur there, 
with transition forms between the two. The cuticular measurements of 
F. bournensis certainly suggest an intermediate position for this fossil 
between F. sylvatica and F. ferruginea (=F. grandifolia).
