The drupes in this species have the remains of the stigma terminal and in this 
respect they agree technically with the diagnosis of Canarium. But they are not equally 
3.sided as in that genus, one side being wider and much more rounded than the 
other two. The structure of the flover is not at all that of Canarium, and the species 
is therefore transferred to Saníiria.
