CRETACEOUS CONIFERALES 15 
we, of course, cannot say, but it determines one point, namely: that 
the species was characterized by at least three needles in a sheath— 
possibly more, but not less.” 
Figure 1, Pl. 22, shows a transverse section of one of the fascicles, 
X 40, from the Androvette pit. The needles may be seen to be 
three in number, enclosed in the remains of the thin membranous 
sheath, with each needle containing a single bundle. At a higher 
plane of section each bundle becomes double. This type of short 
triphyllous fascicle is so constant in its characters, and is so abun- 
dantly represented in the lignitic debris of the Androvette pit, that 
it seems worthy of specific recognition under the name here given 
to it. Ву reason of the fragmentary nature of the remains, however, 
the fact should be borne in mind that in any specimen exhibiting the 
external characters of three needles enclosed in a sheath, these char- 
acters alone, without the corroborative evidence of internal structure, 
can only be regarded as indicating and not as determining its specific 
relationship. The positive identification of the species must always 
depend, primarily, upon the preservation of the specimen being such 
that the internal structure 15 clearly defined.

The remains of this species consist of leaves and leaf fascicles, 
with the leaves normally in fascicles of four. It is the least common 
type of short pine shoots thus far found in any of the deposits at 
Kreischerville. The general characters of the needles are very simi- 
lar to those of most others of the species of Pinus associated with it. 
The bundle sheath in this species is comparable to that described by 
Miss M. C. Stopes in the case of certain Cordaites,** and constitutes 
one of the numerous pieces of evidence which vouch for the primitive
