 the determinations are frequently unreliable and illustrations, when pres- 

 ent, often fail to do justice to the material. 



South America 



The only contribution to the Upper Cretaceous paleobotany of South 

 America is a short unillustrated paper by Kurtz a published in 1902, and 

 describing a small collection of leaves made by Hauthal at Cerro Guido 

 in the province of Santa Cruz, Argentina. 2 The Swedish expedition to 

 South America in 1907-1909 made collections of Upper Cretaceous plants 

 in both Patagonia and Tierra-del-Fuego, but these have not yet been 

 reported upon. 8
