LOWER EOCEXE FLORAS OF SOUTHEASTERN NORTH AMERICA. 



Saxony; 3 Aquitauiun species from Prussia, 

 Boliomia, and Gnn-co; 1 sjiocios from the Bur- 

 digalian of Italy; 1 from tlio Helvetian of 

 Switzerland, and 1 from the Messinian of Italy. 

 Allied to Protea t)ut ])ossil)ly more generalized 

 is the genus Proleoides of Ileer, which includes 

 several Tertiary species and 15 Upper Creta- 

 ceous species. Tliere ai-e 2 species each in the 

 Cenomanian of Bohemia and Lesina, 2 in the 

 Atane beds of Greeidaml, 3 in the Dakota sand- 

 stone of North America, 1 in the Tuscaloosa 

 formation of Alabama, 1 in the Middeudorf 

 arkose mem1)er of the Black Creek formation of 

 South (\irolma, 1 in the Cretaceous of Australia, 



genus Cenarrhenes Laliiil, which includes 1 ex- 

 istuig species in Tasmania, contains a single 

 species rein'cseuted by ])oth foliage and fruit 

 in the Afiocene of Caniiohi, ])ased on a deter- 

 mination ])y Ettingshausen, wliich may well 

 be viewed with susjiicion. The genus Cono- 

 spermum Smith, which contams about .33 ex- 

 isting species in Australia, includes 2 fossil 

 species ui the Oligocene of .Styria and 1 in the 

 Miocene of Carniola. The somewhat less defi- 

 nite genus Conospermites (Ettingshausen, 1867) 

 is represented by a. fossil species in the Upper 

 Cretaceous of Austi'alia and another in the 

 Cenomanian of Saxonv and Bohemia. Fon-

The genus Proteophyllum Velenovsky,' a 

 still more generalized proteaceous type, in- 

 cludes 7 species (Saporta, 1894) in the Albian 

 (Vraconian) of Portugal and 8 species m the 

 Perucer beds (Cenomanian) of Bohemia. An- 

 other generalized type is Proteopsis Velenov- 

 sky, which is represented by a single species m 

 the Cenomanian of Bohemia. The genus Pro- 

 teajphyllum of Fontauie, containing 2 species 

 in the Patuxent formation (Neocomian) of 

 Virgmia, I regard as entirely worthless.^ The

The genus Helicia Loureno is of especial 

 interest, smce it is found farther north in the 

 existmg flora tban any member of the family. 

 There are about 25 modern forms, mostlj^ Indo- 

 Malayiin, as sho^vn on the map (fig. 6), but a 

 few still survive hi Australia, or have recently 

 spread to that continent. The fossil record 

 includes a species m the Oligocene of Styria 

 and another in the Pliocene of Italy. The 

 genus Lambertia Smith, which mcludes 8 ex- 

 isting Australian species, contains a single 

 fossil species in the Miocene of Carniola. The 

 genus Hakea Sclirader, which contains 10(1
