The above are original specimens collected in Styria, Carniola, Croatia, 

 Dalmatia, the Tyrol, Hungary, and Bohemia. 



The recent plants bearing closest analogy to the fossil plants are shown 

 for comparison. 



In the ancient Tertiary strata the Castanea atavia has slightly toothed, 

 or nearly toothless leaves, devoid of thorny points. From the primary 

 vein spring, at a distance from one another, curved secondary veins. 



In the Middle Tertiary strata are found leaves of the Castanea atavia 

 closely approaching the Castanea vesca by approximate secondary veins, 

 and by more numerous and protruding teeth, which, however, are still without 

 thorny points. 



In still more recent strata of the Tertiary formation there are found here 

 and there thorny points on the teeth. 



In the latest Tertiary strata the leaves of the fossil species are nearly 

 identical with those of the Castanea vesca. The secondary veins are more 

 approximate and almost rectilinear, while the teeth are set with thorns. 



In all strata where leaves of the Castanea atavia have been found, the 

 male catkins of that species have also been collected, which differ from those 

 of the Castanea vesca by having somewhat smaller flowers. Examples of 

 these are also added to the collection.
