FURTHER ETHNOPHARMACOLOGICAL NOTES 



ON MALPIGHIACEOUS PLANTS OF THE 



NORTHWESTERN AMAZON 



Richard Evans Schultes 



A number of years ago, I published an article entitled "Notes on 

 toxic or medicinal malpighiaceous species of the Amazon^in Bot. 

 Mus. Leaf]., Harvard Univ. 24 (1975) 12I-131. These notes were 

 based on collections identified by Dr. Jose Cuatrecasas of the 

 Smithsonian Institution — identifications published in his mono- 

 graph of the Malpighiaceae of Colombia in Webbia 13 (1958) 

 343 664. 



During the ensuing eight years, additional collections of this 

 family have been distributed and identified. At present, a total of 

 112 of my numbers have been determined by Dr. William R. 

 Anderson of the University of Michigan — a much more extensive 

 selection than was available to Dr. Cuatrecasas. These identifica- 

 tions have been published in his 'The Botany of the Guiana 

 Highlands^Part XI Malpighiaceae'Mn Mem. N.Y. Bot Card. 32 

 (1981)21-305. 



It is now possible to offer additional notes on the uses of 

 malpighiaceous plants of medicinal or toxicological nature by 

 Indians in the northwest Amazon. Only occasionally have name 

 changes been made. Thus, in great part, there is little need to alter 

 the citation of the notes which I published earlier. 



My deepest appreciation goes to Dr. Anderson for the care and 

 interest which he has show^n in studying my malpighiaceous col- 

 lections. The ethnopharmacological observations are the result of 

 my field research in the Colombian Amazonia from 1941 through 



1954. 



The genera and species are arranged alphabetically. The speci- 

 mens cited are deposited for the most part in the Gray Herbarium
