The present Bnjonia is the commonest one in Formos; i. It differs 

 from It. I'.tritiitilfi ROXB. var. BowrhujMiM in having quite glabrous leaves. 

 The variety Boiri-ini/!.'.inn is always tomentose or pubescent. Tlie Formosau 

 plant should, therefore, Ije another variety of B. lfirin!"fn Roxu. to which 

 Mr. AV. B. HK.MSLKY also refers in Ind. Fl. Sin. I. p. 322. It l>ears some re- 

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

 glabrous leaves.
