{With Plate I.) 



In the Journal of the Linnean Society of London, 1906, I 

 wrote an account of a new genus, Taiwania, 1 * of Coniferae from 

 the Island of Formosa. At that time, I had but a few dry 

 branches with cones, which was, as I have ascertained after- 

 wards, occasionally picked up under a large trunk of this 

 interesting Conifer. I was not, therefore, able to give any 

 account about its histological character, even as much as is 

 requisite in order to systematize the genus. Nor could I 

 supply any notes about its general appearance. It has long- 

 been my desire to secure some alcoholic material for its 

 histological study, and, if possible, to get a photograph of 

 the whole plant, to complete my former description. The 

 habitat of this Conifer is by no means easily accessible, owing 

 to the high elevation and to a deep valley where one can 

 only recognize the tree from the ridge above by its peculiar 

 branching and the colour of its trunk. Fortunately, however, 

 through the kindness of Mr. N. Konishi, I was able to secure 

 what I have been longing after. 



In this paper I have endeavoured to make some remarks 

 on the histology of the leaf, and the description of the whole 

 plant, in addition to my former paper. I will also try to say 

 a few words on the affinity of this genus and other genera.
