CONIFERS. 



4cm. long, and even the largest does not exceed 5cm. in length. In addition 

 to these differences above stated, I may here mention a few more points of 

 distinction between the two species, vix : in the Formosan plant, the bark 

 of the branches of the last year are longitudinally wrinkled but neither at all 

 cleft nor broken, while in the Japanese they are less wrinkled but always broken 

 at the edge of the wrinkles ; seeds of the former are thinly hairy at the base 

 of the wings on the inner surface, while those of the latter are quite glabrous ; 

 and finally, bract-scales are narrower in our species, while they are wider in the 

 Japanese. All these differences, when taken together, make it indisputable to 

 regard our conifer as a species quite distinct from the Japanese congener. 

 The new species is named after Mr. E. H. WILSON whose field knowledge on 

 plants is really extensive and with whom we had many interesting discussions 

 during his stay in Japan 1} .

1). After completing this manuscript, I am informed by Mr. WILSON 

 that a species of Pseudotsuga, called P. sinensis DODE, is published in Bull. 

 Soc. Dendr. France (1912) p. 58, and in Mitt. Deutsch. Dendr. Ges. XXI. (1912) 

 p. 387. Whether my plant is identical with DODE'S species or not, remains 

 as yet questionable. Very probably ours may be different from the Chinese 

 species.
