in the English Eocene; four in the Oligocene of Tyrol, Saxony, 

 Styria and Greece ; ten in the Miocene of France, Italy, Switzerland, 

 Baden, Bohemia, Styria, Croatia, Carniola and Slavonia. A large 

 number of these fossil forms of Pcrsoonia are not especially convic- 

 ing but certainly the three European species Persoonia cuspidate, 

 daphnes, and Myrtillus of Ettingshausen 23 which have the leaves 

 associated with characteristic fruits are above suspicion. 



Bowerbank in his classic study of the pyritized fruits and seeds 

 from the Island of Sheppey established a genus which he called 

 Pctrophiloides from its resemblance to the genus Petrophila R. 

 Brown which has about 35 existing species in Australia, the majority 

 of which are confined to West Australia. Bowerbank described sev- 

 eral species one of which was shown by Starkie Gardner to be an 

 Abuts fruit and others have been referred to Sequoia. Ettings- 

 hausen 24 in the study of the Sheppey fruits after careful comparisons 

 retained three English Eocene species and the genus has also been 

 recognized in the Sannoisian of Dalmatia and Styria. 



The genus Lcucadendrites was established by Saporta for a San- 

 noisian species of southeastern France from its resemblance to 

 Lcucadendron Herm., which has upwards of 70 existing species in 

 South Africa. 



The genus Grevillca R. Brown has 56 existing species confined to 

 Australia. The fossil record includes a Cretaceous species in Aus- 

 tralia; two Cenomanian species in Bohemia {GreviUeophyllum Vel- 

 enovsky) ; three Eocene species in England, France and Italy; twelve 

 Oligocene species mostly in southern France but also represented in 

 Saxony, Tyrol, Bohemia, Styria and Greece ; and twelve Miocene 

 species in France, Switzerland, Bohemia and Croatia. 



The genus Embothrium Forst., already alluded to, has four ex- 

 isting species in South America which range from Chile to the 

 Straits of Magellan, and a fifth species in Australia. This widely 

 separated occurrence is explained when the fossil record is combined 

 with the occurrences referred to Embothrites, EmbotJiriopsis and 

 Embothriophyllum. To Embothrium are referred 8 Oligocene spe-
