Ceanothus, Banksia, Dryophyllum, Sabal, Ficus, Dalbergia, 

 Nerium, Terminalia, and perhaps one hundred additional forms, 

 including even flowers and Acacia-like pods, all unquestionably of 

 Eocene age and closely paralleling the Eocene floras of southern

 which it is in part based are really Lafayette floras. This is
