The leaves are cooked and eaten and are said to turn the teeth 

 red. There is apparently no utilitarian purpose involved in eating 



the leaves. 



The chemistry of this genus is apparently unknown. 



Rl'BIACEAE 



Duroia Linnaeus fi I. 



This tropical American genus of some 20 species belongs to 

 that portion of the Rubiaceae— the Gardeniinae which is not 

 particularly noted for alkaloids with the exception of three gen- 

 era: Randia, Basanacantha and Hamelia. The section has, how- 

 ever, not been thoroughly investigated. In an earlier paper, I 

 indicated the native uses of a number of species of Duroia and 

 noted that "...reports from natives affirming the poisonous 

 properties of the seeds of several species. . .call attention once 

 again to the need for phytochemical studies guided by ethnobo- 

 tanical observations." (Schultes in Bot. Mus. Leafl., Harvard 

 Univ. 22(1969) 151 156).
