Of this species fruiting specimens only are known, yet I am 

 now convinced that it is referable to Blumeodendron, and among 

 the known species of this genus that it is most closely allied to 

 B. tokbrai (Blume) Kurz. I had previously* expressed the 

 opinion that it might be referable to Cheilosa or Alcinneanthus. 

 It is distinguished from the other Philippine species of Blu- 

 meodendron by the prominently reticulate leaves, in this charac- 

 ter resembling B. tokbrai (Bl.) Kurz, of which I now have seven 

 specimens from Java available for comparison.
