4cm. long, aud even the largest does not exceed 5cm. iu leugtb. In addition 

 to these difierences above stated, I may here meution a few more ijoints of 

 distinction between the two species, vix : — in the Formosan plant, the havlc 

 of the liranclies of the last year are longitudiually -nTinlded but neither at all 

 cleft nor brokeu, while in the Japauese they are less wriulded Init always hrolcen 

 at the edge of the wrinldes ; seeds of the former are thinly haiiy at the Ijase 

 of the wings on the iuuer sm-face, wliile those of the hitter are quite glahrous: 

 aud finally, hract-scales are nan-ower iu our species, while they are wider iu the 

 Japanese. All these differeuces, when talcen together, make it indisputahle to 

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

 The new species is uamed after I\Ir. E. H. AVilson whose lield lcnowledge on 

 plants is really exteusive aud with whom we had many iuterestiug disciissions 

 dm-ing his stay in Jaiiau".

1). After comj^leting this manascript, 1 am iuformed by Mr. Wilsok 

 that a species of Pseudotsuga, called P. sinensls Dode, is published in Bull. 

 Soc. Dendr. France (1912) p. 58, aud iu Mitt. Deutsch. Dendr. Ges. XXI. (1912) 

 p. 387. Whether my phint is ideutical with Dode's specics or not, remains 

 as yet questioualile. ^'cry piobably ours may lie diffcreut from the Chiuese 

 siiecies.
