with Descriptions of JVt w Species of Fossil Pla 1 1 



carites have been described from the Cretaceous formatioi . 

 which descriptions are before me: A. acuti folios Endl. and .1. 

 crassifolius Endl. (Synops. Conif. p. 301); neither of which 

 has spathulate leaves. 



There is little doubt that this was a true Araucaria^ and ool 

 very unlike, in its general aspects, some species now living. 



It is also probable that these trees formed extensive fori I 

 on the land during the Chalk period, as I have found the I 

 taceous strata in some localities in the Wesl Literally filled with 

 large trunks of coniferous trees, many of which have rather J !u- 

 structure of Araucaria than of Pi mix, Abies or Jump 

 although all these genera were represented at thai epoch. 



Formation and Locality. Upper Cretaceous strata, Sage 

 Creek, Nebraska. (Dr. Hayden.) 



Nyssa veteista. (n.sp.) 



Leaves large, obovate, entire, thick and smooth, pointed and 

 slightly decurrenton the petiole; nervation strong; midrib Btraight 

 and extending to the summit; lateral nerves pinnate, sel at some- 

 what unequal distances, straight and parallel below, forked and 

 inosculating above, forming a festoon parallel with the margin; 

 tertiary nerves forming an irregular network of polygonal and rela- 

 tively large areoles. 



Of this species there are numerous specimens in the colli 

 tions made by Dr. Hayden in as good preservation as the ma 

 terial in which they arc fossilized will permit. The nervation 

 is strongly marked, and all its more prominenl characti 

 appreciable in the fossil as they were in the fresh ! 

 nervation, consistence, and outline these leaves are almost mm- 

 distinguishable from those of the " Pepperidgi " 

 fiord). The primary and secondary nervation of 

 of Magnolia also exhibit a strong resemblance to that <>\' tl 

 fossils, but a less complete correspondence than Nyssa pi
