18 THE LATER EXTINCT FLORAS OP NORTH AMERICA. 



of which have rather the structure of Araucaria than of Pinus, Abies, or 

 Juniperus, although all these genera were represented at that epoch. 



Formation and locality: Cretaceous (Dakota group). Sage Creek, 

 Nebraska. 



Abietites cretacea Newb. n. sp. 

 PI. XIV, fig. 5. 



Note. — The only manuscript by Dr. Newberry in regard to this figure is on 

 the label attached to the specimen. 



The following description has been prepared from an examination of the 

 specimen: 



Branchlet slender; leaves one-half inch long, crowded, short petiolate, nar- 

 rowly ovate-lanceolate, attenuate at both ends. — A. H. 



Formation and locality: Cretaceous (Dakota group). Whetstone Creek, 

 Santa Fe trail, northeastern New Mexico. 



Sequoia cuneata Newb. 1 

 PI. XIV, figs. 3-4a. 

 Taxodium cuneatum Newb. Boston Journ. Nat. Hist., Vol. VII (1863), p. 517. 



' ' Leaves numerous, short, broad, spatulate in form, rounder or sub- 

 acute at summit, wedge-shaped below, narrowed into a very short petiole, 

 or sessile upon the branchlets." 



The specimens of this plant contained in the collection, though 

 numerous, are too imperfect for satisfactory description. If found in strata 

 of the same age, it might be considered but a variety of Taxodium; but if 

 we can trust the accuracy of the very intelligent gentleman by whom it was 

 collected, it is clearly of Cretaceous age, and therefore, in all probability, 

 quite distinct from any described species. 



The spatulate or cuneate form of the leaves, if this should be found 

 to be a constant character, would serve to distinguish it at • a glance from 

 its Tertiary representatives. 



Formation and locality: Cretaceous (Puget Sound group). Nanaimo, 

 Vancouver Island. 



'This species was transferred by Dr. Newberry from Taxodium to Sequoia in his manu- 

 script. — A. H.
