I have found several species of Ormosia avoided or 
employed as poisons or medicines in the northwest Ama- 
zon, while several other species were not regarded as 
toxic or of economic value. The collections of interest 
are enumerated below. Those for which no information 
relative to biological activity could be elicited from na- 
tive informants are: Ormosia discolor Spr. ex Benth. 
(Rio Apaporis, Colombia: Schultes et Cabrera 12952) 
and O. Williams Rudd (Rio Negro, Colombia: Schu/tes 
et Lopez 9888). 
All of the collections cited have been annotated by 
Rudd and are included in her monograph, with the single 
exception of the new variety described below.
