Jeffry.—On the Affinities of the Genus Yezonia. 771 
importance and certainly cannot be interpreted in any way as indicating 
some affinity between the genus Yezonia and the Cycads as they suggest. 
The consideration of the facts adduced in the foregoing paragraphs for 
Yezonia and Brachyphyllum makes it clear that these two genera agree 
absolutely in the following points : structure, relative size, phyllotaxy and 
venation of the leaves, including the organization and arrangement of the 
stomata in rows between hypodermal bands ; anatomical structure of the 
fibrovascular tissues, including irregular zonal variations in the thickness of 
the tracheides not in any way corresponding to annual rings, pitting of the 
tracheides, height of the medullary rays ; structure of the pith and cortex, 
stone cells being present in both; structure of the phloem devoid of the 
hard bast fibres characteristic of Cupressineous and Taxodineous Conifers ; 
and finally by the presence of a broad transfusion zone in the outer region 
of the stem corresponding to the lower surface of the appressed leaves. 
Or to put the matter in another way, if all the points of agreement 
between the description of the supposed new genus Yezonia , given on p. 32 
of the memoir of Stopes and Fujii, and the account of the anatomy and 
habit of Brachyphyllum , given in the present article and in the large memoir 
of Dr. Hollick and the present author, were italicized, it would be necessary 
to italicize the whole description. 
It is appropriate at this point to refer to another supposed new 
Gymnospermous genus described by the Anglo-Japanese authors. On 
pp. 52-7 of their memoir they refer to certain remains, which they 
designate under the name Cryptomeriopsis antiqua. These are characterized 
as densely leafy twigs, with falcate four-sided foliar organs, which have 
internally a single fibrovascular bundle flanked by downwardly curving 
stripes of transfusion tissue. There are three foliar resin canals. The stem 
possesses a woody cylinder traversed by low uniseriate rays, and the phloem 
is without the hard bast fibres found in living representatives of the 
Cupressineae and Taxodineae. In the pith were found evidences of the 
presence of stone cells. All these details of structure correspond absolutely 
with the account of the structure of Geinitzia ( Sequoia ) Reichenbachi , one of 
the commonest Cretaceous Conifers, given in the joint memoir by Dr. Hol¬ 
lick and the writer (op. cit., pp. 38-41, PI. 5, Figs. 7-10, PL 8, Figs. 3 and 4, 
PI. 16, Pdgs. 2-4, PI. 17, Figs. 1-4, PI. 18, Figs. 1-4). There can 
accordingly be little doubt that the Cryptomeriopsis antiqua of Stopes and 
Fujii is in reality not allied in any way to the Cupressineae and Taxo¬ 
dineae, but represents the leafy twigs of the well-known Cretaceous species 
Geinitzia {Sequoia) Reichenbachi , which, as has been pointed out by 
Dr. Hollick and the writer in the memoir so often cited in the present 
article, is in reality an Araucarian Conifer and has not the slightest affinity 
with the existing genus Sequoia , to which it has been most generally
