Discussion:

A common riverine tree widely distributed in tropical America, general and reasonably constant in Guiana. In interior British Guiana, especially in the vicinity of the Pakaraima Mountains (in Guayana), the leaflets are somewhat fewer and broader, and an olive tomentum occurs on the inflorescence axis and branches. Similar deviations are expressed more strongly south of Amazonia. The cited Amapa collections are first reports for that territory. The remarkable enantiopetaly is seldom apparent from dried preparations.
