The present Btyouia is the commonest one in Formosa. It differs 

 from B. laciniata ROXB. var. Bowringiana in having quite glabrous leaves. 

 The variety Bowringiana is always tomentose or pubescent. The Formosaii 

 plant should, therefore, be another variety of />. ladniaia, ROXB. to which 

 Mr. W. B. HEMSLEY also refers in Ind. Fl. Sin. I. p. 322. It bears some re- 

 semblance to B. xi.nensis, but differs from that in having larger flowers and 

 glabrous leaves.
