MATERIALS FOR A FLORA OF FORMOSA. 115 
The present plant is first mentioned by Dr. T. Ivo, jointly 
with Prof. J. Marsumura, in their Tent. Fl. Lutch. p. 487 and 
afterwards is corroborated by myself in Enum. Pl. Formos. p. 148. 
After having examining the type of B. hirsuta Buume. at Kew* 
I have found that the type is far different from the present plant, 
and Iam very much inclined to regard it as a species distinct 
from Buiume’s. Our plant has, as metioned by Prof, J. Marsv- 
mMuRA, “smaller stamens, shortly spurred posteriorly, a little 
auricled anteriorly, and anthers 1-porose, 2-auricled on the 
anterior side, connective not at all or very shortly produced, tuber- 
culate on the posterior side.”
