CRETACEOUS CONIFERALES 29 
5, Pl. 19, is a view of a longitudinal section, X 20, of a rather badly 
preserved twig, illustrating the transverse cracks, which are a fre- 
quent feature of fossilization in these and other similarly preserved 
specimens, which feature, as previously suggested by the senior 
author," led Newberry into the error of referring certain partly 
decorticated twigs of /’iddringtonites to Frenelopsis,8 on account 
of the resemblance of these cracks to joints or articulations. Figure 
6, Pl. 19, shows a longitudinal section, X 20, passing through the 
broken apex of a leaf on the upper surface of another specimen. Ву 
the use of a lens sclerites can be made out in the cortex of the upper 
surface and in the pith (nearly opposite the termination of the leaf). 
Figure 1, Pl. 20, is a longitudinal section of the wood, X 500, 
showing the radial pitting. The pits are fewer in this species 
than in any other which we have examined, on account no doubt 
of its extremely xerophytic habit and it is not easy in all sections 
to find the araucarineous type of pitting. This can, however, 
generally be observed in the ends of certain of the tracheids, as 15 
shown in the figure last mentioned, in which the pits may be seen to 
be obviously flattened by mutual pressure in the typical araucarian 
fashion. We therefore conclude, from the internal structure of the 
twigs of these remains, that there is no reasonable doubt as to their 
araucarineous affinities, and if we have correctly identified them as 
the remains of Raritania this determines the correct systematic posi- 
tion of the genus.
