Tliis new douglasfir was formerly regarded by several botanists aud also 

 by mj'self as identical with the Japauese spiecies, Pseudotsuga japonica (Shir.\.- 

 sawa). The distinction between the former and the latter was recently suggested 

 by Mr. E. H. Wilson of the Arnold arboretum, who was at that time devo- 

 ting himself to tlie study and coUectiou of the Japanese conifers. After a care- 

 ful observatiou on the Japanese species at the native places, the said geutle- 

 man examiued attentively the Formosan plant in our herbarium. The points 

 of distinction between the two spiecies indicated by him are, first of all, the 

 dark chestnut-colom-ed slioots on the Formosan conifer and the pale yellowish 

 slioot ou the Japanese ; secondly the buds of the foi-mer are elliptical and 

 obtuse at the apex and the bud-scales are conspicuously ciliate, while those of 

 the latter are more or less cylindiical and acute at the apex and the bud-scales 

 are not at all or very faintly ciliate ; in the third place, the shoots of the For- 

 mosan fir are thinly clothed with browuish hairs, but those of the Jajjauese are 

 perfectly glabrous ; in the fourth place, the seeds of the new species are (wings 

 being taken together) much larger and the wings are more or less rounded at 

 both apex aud base, while those of the Jaijanese are smaller, and the wings are 

 more or less cuneately obtuse at both ends ; and finally the coues of the former 

 are a little larger, usually 4|-6 cm. iu length, while those of the latter are usually
