76 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
not formed. Rays strictly araucarineous, with pits on the walls in 
contact with the tracheids only. Leaves not on short shoots, various. 
Female cone scales squamiform, deciduous (./gathis, Araucaria, 
Albertia (?), Pseudo- Araucaria (?)) 
It appears probable that the above order of enumeration of the 
sub-tribes corresponds to their phylogenetic sequence, the са 
pityoideae being the oldest. 
SUMMARY 
1. By special means of isolation we have been able to secure from 
the Androvette and Drummond clay pits at Kreischerville, Staten 
Island, N. Y., structural material of leafy twigs, cone scales and 
fragments of lignite, representing a considerable number of impor- 
tant Cretaceous coniferous genera. 
2. Some of these remains are genera already known from. impres- 
sions, others represent genera which are new to science. 
3. The coniferous flora of the Androvette pit consists of abun- 
dant remains of species of Pinus and of other conifers, which have 
been referred to genera supposed from the habit of their leafy 
branches, or of their cones, or of both, to belong to the Sequoiineae, 
the Cupressineae and the Podocarpineae. 
4. The conifers referred on their superficial characters to the 
Sequoiineae, Cupressineae and Podocarpineae, turn out from micro- 
scopic examination of their leafy twigs and cone scales to belong to 
the Araucarineae. 
5. They represent a special sub-tribe of the Araucarineae, for 
which the name Brachyphylloideae is proposed. 
6. These conifers are characterized by a special type of wood, 
which we designate Brachyoxylon. 
7. The wood structure of the Brachyphylloideae clearly allies 
them with both the Araucarineae (in the narrower sense) and the 
Abietineae. 
8. Thereis good evidence that the Araucarineae have come through 
the Brachyphylloideae from ancestors allied to the Abietineae. 
9. The abietineous remains from the Androvette pit belong to 
the genera Prepinus and Pinus. The species of Pinus are in general 
more archaic than any living species. Prepinus shows features of 
structure more primitive than those known to exist in any other 
conifer living or extinct.
