OF THE MATTO GROSSO EXPEDITION, 1891-92, 379 
I have shown specimens of this species side by side with those of Psychotria stipulosa to 
several of my friends, and all have been struck by the remarkable homoplasy. It has 
in fact been suggested that the two are really one species, but the inflorescences are so 
unlike that I cannot think this to be possible. [ Amazonia. ]

Dried material of this very important plant is searce ; in fact I do not remember to-

brought specimens home with me. I did not do so, thinking that, on arriving in this.
