160 BERRY— LOWER EOCENE FLORA OF [April 25, 



species has eleven fossil species in the Oligocene of Europe; in 

 France, the Tyrol, Saxony and Greece; and no less than 17 Miocene 

 species in France, Italy, Switzerland, Baden, Hesse, Prussia, Bohe- 

 mia, Austria, Styria, Croatia and Hungary. 



The genus Knightia R. Brown with a modern species in Australia 

 and 2 in New Caledonia has a fossil form in the Eocene of Australia 

 and another in Graham Land"- in beds regarded as Oligocene. The 

 allied genus Knightites Saporta has two species in the Sannoisian 

 of France. 



The remarkable genus Lomatia, previously mentioned, has four 

 existing species in Australia, 2 in Tasmania and 3 in Chile. As 

 might be expected from their modern isolated occurrences there are 

 over 30 fossil species based in some cases on associated leaves and 

 fruits. The oldest of these are two (perhaps wrongly identified) 

 species in the Dakota Sandstone. Eocene records include the Green 

 River shales of North America, a Ypresian species from the south 

 of England, an Italian species, five Australian and one Tasmanian 

 species. There are about a dozen Oligocene species, some of which 

 are very characteristic. They occur in the Tyrol, Saxony, Baltic 

 Prussia and Styria, and the relatively large number of four are 

 recorded by Dusen from Graham Land (Antarctica). There are also 

 about a dozen Miocene species recorded from such separated areas 

 as Colorado, Switzerland and Carniola. The wonderfully preserved 

 leaves in the volcanic ash beds at Florissant, Colorado, from which 

 seven forms have been described, the only known Miocene occurrence 

 of Lomatia in North America, are alone sufficient to confound the 

 sceptics. 



The allied genus Lomatites Saporta has a Cenomanian species in 

 Saxony and five or six Oligocene species in France. The genus 

 Stenocarpus R. Brown, with 11 existing species in New Caledonia 

 and 3 additional ranging from North Australia to New South Wales, 

 has a single fossil species in the Oligocene of Saxony. 



The genus Persoonia Smith has 60 existing species in Australia 

 and one in New Zealand. The fossil record includes two widely 

 distributed species in the Upper Cretaceous of North America ; one
