66 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
the general Cupressinoxylon type. This group of conifers needs a 
much more comprehensive study than it has received before it will 
be possible to distinguish clearly its characters, either ligneous or 
reproductive. 
It is apparent from the data in regard to the Cupressinoxylon 
from Staten Island, above recorded, that the possibility of the exist- 
ence of cupressineous conifers at so early a period is not excluded, 
although it is obvious that they could not have been very numerous. 
We hope to return to this phase of the subject on another occasion, 
when more abundant material may be at our disposal.

Remains consisting of small, slender cones, much longer than 
broad; scales lanceolate-ovate, acute, closely imbricated, bearing on 
their edges numerous pollen grains or microspores, each of which is 
provided with two lateral wings or air sacs. 
In the lignitic debris of the Androvette pit occur numerous 
minute, slender cone axes, almost never complete, covered with very 
small scales. The scales have often about their edges a yellowish 
brown substance, which on superficial examination appears to be of 
the nature of a resinous exudation. This substance, when viewed 
with the microscope in favorable cases, is seen to be made up of 
pollen grains or microspores, bearing two lateral wings, such as 
occur among living coniferous pollens in the Abietineae and Podo- 
carpineae. The small cones which produce these microspores are 
obviously male aments of a conifer. It would be inferred from their 
pollen grains alone that they are either abietineous or podocarpineous 
in their nature. 
Figures 18-21, Pl. 10, show the superficial characters of these 
male aments, X 10. Their length and slender proportions, when 
complete, make it difficult to regard them as belonging to the Abie- 
tineae, ıf such a reference were not negatived by their internal struc- 
ture, as will be indicated at a later stage. The outward configuration 
of the scales is more in favor of their podocarpineous affinities, but
