250 Berry : Araucarian remains 



ranged from Greenland to New Jersey and Montana. Unfortun- 

 ately, the more familiar generic term for those plants, Dammar a, 

 is a pre-Linnean name, having been proposed by Rumphius in 

 1 741,* so that recently systematists have taken up the name 

 Agathis proposed by Salisbury in i8o7.f

The genus Araucaria is chiefly oriental, with eight or nine 

 species, all but one belonging to Endlicher's subgenus Eutacta, 



(1847), characterized by more or less acicular, keeled leaves and 

 winged cone-scales. This subgenus is not represented in South 

 America, the two or three species from that continent being refer- 

 able to the subgenus Columbea (Salisbury, 1807), characterized by 

 broad flat leaves, and with one species, Araucaria Bidwilli, in the 

 Australian region (the "Bunya-Bunya " of southern Queensland). 

 It will be noted also that North America, Europe, Africa, and 

 practically all of Asia contain no representatives of this subfamily. 



It is not my purpose to sketch the past history of this group, 

 a task recently performed by Seward & Ford, who point out the 

 probable Araucarian affinity of the Paleozoic genera Walchia, 

 Schizodendron {Tylodendron), Gomphostrobus, and the possible 

 Araucarian relation of the Triassic genera Albertia, Voltzia, Ull- 

 mannia, etc. It is, however, desirable to indicate briefly the prob- 

 able range of the Araucarieae during the period when the species 

 about to be described flourished, i. e., the Cretaceous. 



The recorded occurrences of Araucarieae during the Cretaceous 

 are shown in figure 2. No attempt has been made to revise these 

 data, which may in some instances be based upon insufficient evi- 

 dence, nor have obviously allied genera like Brachyphyllum been 

 included, or any of the many species described as Sequoias, some 

 at least of which would seem to be more properly referable to the 

 Araucarieae. 



By referring to the map (figure 2), it will be seen that in the 

 Western Hemisphere we have Agathis from 70 north latitude 

 (Greenland), and Araucaria from 40 south latitude (Patagonia), 

 with several species of both genera in the United States, ranging 

 from Block Island to South Carolina on the east coast and from 

 Montana to Kansas in the western interior. In the Eastern Hemi-
