MATERIALS FOE A FLORA OF FORMOSA. 115 



The present plant is first mentioned by Dr. T. Itô, jointly 

 with Prof. J. Matsumura, in their Tent. Fl. Lutch. p. 487 and 

 afterwards is corroborated by myself in Enum. PL Formes, p. 148. 

 After having examining the type of B. hirsuta Blume, at Kew* 

 I have found that the type is far different from the present plant, 

 and I am very much inclined to regard it as a species distinct 

 from Blume' s . Our plant has, as metioned by Prof. J. Matsu- 

 mura, " smaller , stamens, shortly spurred posteriorly, a little 

 auricled anteriorly, and anthers 1 -poröse, 2-auricled on the 

 anterior side, connective not at all or very shortly produced, tuber- 

 culate on the posterior side."
