4,2 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
GEINITZIA Sp. 
Plate 8, figs. 5, 6; Pl. 18, figs. 5, 6; Pl. 19, figs. 1, 2 
In figs. 5, 6, Pl. 8, are shown opposite sides of a leafy twig, X 10, 
which has a close resemblance to the species last described, although 
the leaves may be seen to be more slender and less closely arranged 
on the twig. We have been unable to definitely refer this specimen 
to any one of the so-called Sequoia species, although it is suggestive 
of certain forms of 8. subulata Heer, from the Cretaceous of Green- 
land,*? and some others of the closely allied Cretaceous species, with 
one or another of which it may ultimately be proved to be identical. 
The internal structure, however, shows it to be so closely allied to 
G. Reichenbachi that no matter how it may be referred it cannot 
possibly be regarded as a Sequoia, but should be included in the 
genus Geinitzia. 
Figure 5, Pl. 18, shows a transverse section of this specimen, 
X 40. "The stem is much slenderer than is the case in the average 
branches of G. Reichenbachi, but it presents the same general fea- 
tures of structure. The leaves in the specimen under discussion, 
however, contain but a single resin canal. Figure 6, Pl. 18, shows 
a somewhat larger and better preserved specimen of apparently the 
same species, in transverse section, X 25. e leaf has the same 
single resin duct. In the pith may be made out stone cells similar 
to those found in С. Reichenbachi. 
Figure 1, Pl. r9, shows the structure of the wood and phloem, as 
seen in transverse section, X 150. The wood is without resin cells, 
as in С. Reichenbachi. ‘The phloem is well preserved and shows 
general features such as are found in all those araucarians of which 
Brachyphyllum and Geinitzia may stand as types. Figure 2, Pl. 19, 
shows a longitudinal approximately radial section of the wood of 
this species, X 180. In a single tracheid the pits are flattened by 
mutual contact, while in the others they are generally round. There 
can be no doubt that in this species also we have to do with an arau- 
carineous and not with a sequolineous conifer, and have further 
evidence which confirms the suspicion that other, if not all of the 
so-called Sequoias from the Cretaceous do not belong to that genus 
but to some genus or genera which represent a peculiar and probably 
extinct type of vegetation.
