to be made out distinctly. The preservation of the paren- 

 clrymatous cells of the primary cortex is not good. 



Periderm. Three distinct periderms are preserved in the 

 axis of the largest diameter which is 3 years old. Each 

 periderm consists of the outer many cork-cell layers and inner 

 2 or 3 thick walled phello derm-cell layers. The different 

 periderms show more or less differences in their developmental 

 stages and frequently stone cells occur in the phelloderm of the 

 outermost periderm (Phot. 4, PI. VII). The innermost periderm 

 is developed in the secondary phloem. In the younger twig, 

 we see only one peridermal development in the cortical region. 

 Thus, the development of the periderms and the bark formation 

 resemble most those of Taxodiinsd and Cupressinea?. 



The leaf-trace is a single strand as in Cryptomeriopsis antiqua 

 (Stopes and Fujii 11), Cryptomeria and many other conifers. 



Leaves. The leaves are of Cryptomerian type in general 

 appearance and arrangement (Text-fig. 1) and decurrent with 

 broad base, and enclosing ^ or \ around the axis (Phot. 3, PL 

 VII). The transverse section of the leaf is like Cryptomeriopsis 

 antiqua, generally of a rhomboid al shape, somewhat laterally 

 extended. The height and breadth may differ, however, in 

 different leaves, as it is the case with Cryptomeria in which 

 we see a kind of seasonal dimorphism of leaves. 



Epidermis and stomates. The epidermal cells and stomates 

 are usually not well preserved. One longitudinal section through 

 a leaf show them rather well. They seem to be of the normal 

 gymnospermous tj^pe. The stomates are distributed on the 

 lower surface, namely on the outer surface, while they seem to 

 be absent on the upper surface, namely on the inner surface. 



Hypoderma. The sclerenchyma.tic hypoderma of the leaf is 

 developed in the lower side only, that is, in the outer side of 

 the leaf. It is generally cf a single row of cells, except towards 

 the median longitudinal line of the leaf where even 6 layers of 

 ln T podermic sclerized cells may be found. The sclerenchyma 

 is interrupted by the stomates. 



Palisade Tissue. There is well differentiated palisade tissue 

 under the hypoderma. The inner ground tissue consists of
