The figure given by Emmons of this plant, as before stated, is, I 
think, misleading. I did not find the specimen that he illustrated, 
but saw others that appear to belong to this species. They are not 
P. longifolius, and agree pretty well with Emmons’s figure. If we 
may judge from these, the figure mentioned makes the leaflets too 
rigid in aspect, with a petiole too long and strong. The basal portions, 
also, are made to appear too thick. Emmons makes all the insertions 
of the leaflets well within the margins and on the upper face of the 
midrib. They appear to be arranged in a long spiral, like those of 
P. longifolius. Some of the insertions are on the upper face and some 
on the side. The leaflets contrast strongly with those of P. longifolius. 
They are thin in texture and show the nerves very distinctly. The 
latter are as given by Emmons. The leaves are wider, in proportion 
to their length, than those of P. longifolius, but the width, in propor- 
tion to length, is not quite so great as is given by Emmons. Fig. 1 
of Pl. XLII gives the most complete specimen seen by me. It is much 
more fragmentary than the specimen figured by Emmons. The leaf- 
lets appear to be more deciduous than thoseof P. longifolius. Emmons 
mentioned that some of the detached leaflets are half an inch wide. 
I saw none so large. Fig. 2 shows the largest seen. Possibly this is 
a different species from both of those described.

Emmons does not seem to have seen in the North Carolina beds 
Podozamites tenuistriatus, which, perhaps, is the most common cycad 
of the Older Mesozoic of Virginia. His collection at Williams College, 
however, shows several well-characterized specimens of this species. 
They agree best with the larger forms as shown in the Virginia beds, 
but some of the leaflets are rather larger than any seen in the Vir- 
ginia strata. Pl. XLII, Fig. 3, represents one of the specimens with 
small leaflets.
