16 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
nature of the genus Pinus. A similar sheath is also present in P. 
triphylla, and in the species next described, but in the former it is 
much less well marked and is scarcely obvious in the low scale of 
magnification used in the illustration of the characters of that 
species, shown in fig. 1, Pl. 22. 
A transverse section, X 40, through a fascicle of P. tetraphylla, 
is shown in fig. 4, Pl. 22, in which the inner sheath of the transfusion 
tissue may clearly be seen to pass as a radial stripe through the four 
foliar traces, separating each of them into two bundles such as are 
universally found in the hard pines. 
Locality: Androvette pit. Collected by E. C. Jeffrey and Arthur 
Hollick. Specimen in Jeffrey collection, Cambridge, Mass. 
Pinus quinquefolia sp. nov. 
Plate 22, fig. 2 
Remains consisting of leaves and leaf fascicles. Leaves normally 
in fascicles of five, enclosed below in a membranous sheath and with 
two fibrovascular bundles in each leaf. Transfusion tissue present- 
ing the same characters as in P. tetraphylla. 
The brachyblasts of this species are much stouter than those of 
P. triphylla. “They present the same fragmentary condition of pres- 
ervation, but the remains are less abundantly represented in the 
material from the Androvette pit. Figure 2, Pl. 22, shows the 
characters of P. quinquefolia as they appear in a transverse section 
of а fascicle, X 40. The sheath is only partially present.

Cone Scales of PINUS sp. 
Plate 9, figs. 11, 12; Pl. 23, fig. 6 
A few cone scales of Pinus have been found in the macerated 
material from the Androvette pit. Most of these are in a very bad 
condition of preservation, which does not make easy a clear inter- 
pretation of either their internal or external features of structure. 
In figs. 1 1, 12, Pl. 9, are shown the upper and lower surfaces respect- 
ively of one typical cone scale, X 10. The inferior view of the 
scale shows the presence of a well marked apophysis and a median 
umbo. The superior aspect of the scale is so well preserved by par-
