Grows also in N. Brazil to Panama. The pistil and staminal column I have seen con- 

 siderably more elongated in American than in African specimens. The specimen collected 

 by Barter on the Niger is in bud and is accompanied by a globose several-seeded fruit, ao 

 far as the leaves and flowers are concerned, T find no ground whatever for regarding it as 

 distinct from Mr. Mann's specimens, but the difference in the fruit and seeds— the latter 

 being nearly smooth and not siuuous-rugose as in Mann's plant (the true S. globuhfera) — 

 leads me to think it may prove distinct and perhaps a species of Chrysopia, Thouars ( PI. et 

 Tr.). If so, it confirms the propriety of uniting Chrysopia with Symphonia, as is done 

 in the ' Genera Plantarum ' (1. c). In Barter's plant, the seeds have a separable papery 

 testa ; in Mann's, the testa appears to be closely adherent to the embryo, following the 

 convolutions of its surface. Barter says this tree yields " a gum like gamboge.
