65 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
The fact that air chambers occur in the pollen of two groups so 
widely separated geographically as the Abietineae and Podocarpineae 
makes it possible that the presence of air cells in the pollen grains 
of the Coniferales is an ancient character and that in the older repre- 
sentatives of various tribes they may have had a much wider distri- 
bution than at present. The structure of the sporophylls in our 
fossil points strongly to its araucarineous affinities. In neither the 
Abietineae nor the Podocarpineae, as far as we have observed, do 
the leaf traces of the sporophylls become surrounded in their upper 
region by a cordon of transfusion tissue. This feature is strikingly 
araucarineous. It seems accordingly not unlikely that our fossil 
belongs to this tribe. This probability is enhanced by the abietineous 
features of wood structure found in a large number of the araucari- 
neous species described from the Androvette pit. Fliche, in his 
“ Études sur la Flore Fossile de Argonne,” has described and 
figured three species of Cretaceous cones under the new genus Pseudo- 
draucaria. These are female cones, characterized by the presence 
of two seeds оп the cone scale as in the Abietineae and a less pro- 
found fusion between the ovuliferous and sterile scales than is found 
in the genus draucaria. Оп the whole it appears not improbable 
that the slender male cones which we have found in the Cretaceous 
deposits at Kreischerville belonged to a generalized araucarineous 
type, nearer in the structure of its male sporophylls to the Abietineae 
than are any of the existing Araucarineae. It may well have been 
one of the numerous genera with the Brachyoxylon type of wood 
structure, which have been described in the foregoing pages.

Plate 3, fig. 10 
Cone linear-elliptical in outline, about 5 cm. in length by 2.5 cm. 
in width at the middle; scales numerous, relatively thin, closely 
imbricated. | 
This 18 the most perfect cone thus far obtained from the Kreischer- 
ville deposits, and it more or less resembles certain Cretaceous cones
