Caryocar glabrum is widespread in the Amazon valley and the 

 Guianas. In the Colombian Vaupes, this tree is known in Span- 

 ish as barbasco de monte and barbasco propio. The Puinvave 

 Indians call it ho'-shoo or haw. The Kubeos refer to the tree as 

 kon. In Barasana, the name is e-ho'. The Maku Indians on the 

 Brazilian Rio Unciuxi know it as pursh. Prance reported the 

 use of this species as fish poison amongst the Maku (14).
