In my paper above cited, I mention that the present plant is referable 

 to Hypericum atlenuatum CHOIS., although there have been some doubts 

 about its being identical with CHOISY'S plant. While studying here at 

 Kew, I have compared the plant with the type of the species and found that 

 they are so very different that it hardly needs poiutiug out. The Forrnosan 

 plant comes very near H. perforalum ; but differs from it in having ob- 

 tuse or even rounded sepals. H. perforation has usually very acute sepals.
