'■^ In the year 1901, a new genus of Styraceœ, Alniphi/l/um, ^Yas established by 

 Prof. J. Matsumura, in Tokyo Bot. Mag. XV. p. 67. The above mentioned 

 A. pferôspermum is the only sj^ecies belonging to the new genus. No other species 

 had ever been known to us, until Mr. J. Perkins found another species,-''^ A. 

 macranthum, from China which he described in his *' Beiträge zur Kenntnis der 

 Stijracaceœ " in Engler, Bot. Jahrb. XXXI. p. 487. The specimen upon which 

 Prof. J. Matsumura based his description is quite a perfect one, having flowers 

 of various stages, fruits and seeds. But Mr. J. Perkins' specimen, I infer, must 

 liave been an imperfect one, being deficient of fruits and seeds, as he lias no 

 description of them in his diagnosis. 



While investigating the Formosan plants in the Herbarium of the 

 Imperial University of Tokyo, under the supervision of Prof. J. Matsumura, 

 I have lieen fortunate to examine the same specimens upon whicli the Professor 

 described his new genus. In studying the genius carefully, I was struck witli 

 the singularity of its fruits and seeds, which reminded me of those of Erieaceœ. 

 The species seems to be Styraceœ, so far as the external forms of the tree and 

 flower are concerned. But a little more minute examination shows it to be 

 nearer to Eneaeex than to Styraceœ. 



* Perkins' species is rendered to be a synonym of .1, pteiospermnm by Hemslky, in Hook. If. PI. XXVIII. 

 PI. 2791.
