28 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
that this cone has much the appearance of those which have been 
figured in connection with branches of Inolepis imbricata Heer,?* 
from the Cretaceous of Greenland, but the leaves do not agree, while 
the external resemblance between the peduncle and the twigs in our 
specimens is so strong that there can scarcely be any doubt that these 
are generically if not specifically identical with each other. Figure 
17, Pl. 10, shows the same cone, X 10, and there is enough of the 
surface sculpturing still remaining to indicate that the scales were 
spirally arranged and were not, externally at least, divided into two 
segments, as in the case of the Abietineae. 
From the preceding discussion it may be inferred that the results 
obtained from the studies of the external characters of the specimens 
were not entirely conclusive either as to their identity with the genus 
Raritania or as to their exact botanical relationship; but, as may be 
learned from the discussion which follows, the internal structure was 
found to afford a much more satisfactory field of investigation. 
Figure 3, Pl. 19, shows the internal structure, in transverse section, 
X 30, of the twig shown in fig. 3, Pl. 9. The woody cylinder is 
immature and is badly preserved. The cortex is confluent with the 
decurrent leaf bases and is characterized by the presence of a consid- 
erable number of stone cells, which have mostly disappeared in 
charred specimens like that under discussion, but are more apparent 
in badly preserved material. There are indications of four leaves 
on the periphery of the section, each of which shows a more or less 
apparent resin canal, which exactly subtends the foliar traces. 
Figure 4, Pl. 19, shows a transverse section, X 45, of the stouter 
twig shown in fig. 1, Pl. 9. An attached leaf may be seen on the 
upper side. It contains a resin canal which communicates with the 
surface of the stem by means of a crack, a result of the condition 
of fossilization. On the right is a resin canal in the cortical tissues 
which marks the position of the decurrent portion of another 
leaf. On the upper side of the section the tissues of the phloem are 
partially preserved and these strongly resemble those found 1 
Geinitzia (see this Memoir, pp. 40-42). The woody cylinder is 15 
remarkably well preserved in this specimen and presents the same 
general features of microscopic structure as in Brachyphyllum 
(see this Memoir, p. 33); but the pith is relatively smaller than 
in either of the other two araucarineous types mentioned. Figure
