I9I4-] SOUTHEASTERN NORTH AMERICA. 199 



There are also about thirty Oligocene species, all European, and in- 

 cluding remains in the Baltic amber, in France, Switzerland, Ger- 

 many, Austria-Hungary and Greece. There are at least a dozen 

 species in the Chattian of Bohemia. Over fifty Miocene species have 

 been described ranging throughout Europe, in eastern Asia, and in 

 Virginia, Colorado, Idaho and Oregon in this country. About a 

 dozen Pliocene species have been described from Spain, France, 

 Italy and Sicily. 



The genera Cassine Linne and Pterocelastrus Meissner both now 

 confined to South Africa and Madagascar, each has a fossil species 

 in the Miocene of Bohemia. The genus Pachystima Rafinesque, with 

 two existing species in North America, has an Upper Cretaceous 

 species in North Carolina and a Miocene species in Colorado. 



The genus Maytenus Feuill, with about 70 existing species of 

 the tropics and subtropics of South America has a well-marked 

 species in the Wilcox flora. There are two species in the early 

 Tertiary of Chili, one in the late Oligocene and three in the Miocene 

 of southeastern Europe. 



The monotypic genus Gyminda Sargent confined to Florida and 

 the West Indies in the existing flora has a doubtfully determined 

 fossil species in the Magothy formation of the Atlantic Costal Plain. 

 The genus Microtropis Wall., with 9 or 10 existing species of the 

 mountains of southeastern Asia from India to China and Japan, has a 

 doubtfully determined form in the early Pliocene of Italy. 



A well preserved flower in the Baltic amber is described by 

 Conwentz as Celastriiiaiitliium Hauchecomei. 



The genus Elccodendron Jacquin, with about 25 existing species 

 confined to South Africa, has a considerable geologic history. Four 

 Upper Cretaceous species have been described — one from Australia, 

 one from the Dakota sandstone, and two from the Magothy forma- 

 tion of the Atlantic coast. There are six Eocene species showing 

 that the genus was represented in New Zealand (?), Australia (?), 

 Alaska, the Ypresian of England and the Fort Union of the Rocky 

 Mountain region. There are five Oligocene species in the Tyrol, 

 Bohemia and Transylvania ; nine Miocene species in France, Switzer- 

 land, Italy, Prussia, Bohemia and Styria ; and four Pliocene species 

 in Italy.
