Tins plant very much resembles to the Looclni plant Osmunthus 

 bractcatus, but in that one flowers make a raceme and have many 

 bracts and a little smaller than those of this. Inflorescence is alike to 

 that, of the Bonis one (). itisulnris, but leaves are more coriaceous, 

 broader and not so acuminate. It is said (hat this plant was brought 

 up and planted in the garden by the late foreman ToMTJIKO 1 Ymiyama, 

 but no one knows where he had got it. Without flowers Qobody can 

 hardly separate this from (). bracteatllS and we thought this to be that. 



Bui this year its firsl blossom- appeared, by which we readily 

 distinguished this from it.
