Colombia: Comisaria del Amazonas, Rio Loretoyacu. October 1946. Schultes 

 et Garcia- Barriga 8418. 



This species is one of the preferred curare plants amongst the 

 Kofan Indians of the Colombian Putumayo and adjacent 

 Ecuador (Schultes: Bot. Mus. Leafl., Harvard Univ. 13 (1949) 



289). 



The Tikunas of the Rio Loretoyacu recognize the bark of the 

 stem and root as toxic but have no knowledge of its use in 



preparing curare. 



The Tikunas have long had great fame as curare-makers. 

 Their curare was made basically from Strychnos and species of 

 several menispermaceous genera. Krukoff, who investigated 

 Tikuna arrow poisons in great depth, failed also to list 

 Schoenobiblus peruvianus as one of the ingredients of Tikuna 

 curare (Krukoff and Smith: Bull. Torr. Bot. Club 64 (1937) 

 401-409.).
