Nageiopsis of. NT. heterophylla, Font. 1 



[PL XII. Fig. 3.] 



The few small fragments from the English beds bear a strong 

 resemblance to the specimen figured by Fontaine as Nageiopsis 

 heterophylla, and most probably belong to this species. 



V. 3190. PI. XII. Fig. 3. 



Compare Fontaine, pi. Ixxxvi. figs. 6 and 7, etc. There are 

 several equal veins in each leaf which converge somewhat towards 

 the apex ; the leaves are gradually tapered distally, and towards 

 the point of attachment. The actual manner of attachment to 

 the branch is not clearly shown. Near Hastings. Rwfford Coll.

Probably the same species, but much more imperfect. Eccles-

Saporta 2 includes in the tribe Araucarinea two genera, Pachy- 

 phyllum and Araucaria ; the former representing the extinct types, 

 the latter the living species. Pachyphyllum was first instituted 

 by Pomel 3 as a section of his genus Moreania, including M. brevi- 

 folia, Pom., as the typical species. 



Saporta figures some examples of the genus in which portions 

 of cones are preserved, and is thus able to give a fairly detailed 

 diagnosis. He places Pachyphyllum close to Araucaria (Eutacta), 

 Agathis, and Cunninghamia. The general appearance of the
