Distribution and habitat: — Nicaragua , Costa Rica , Bolivia , Colombia , Ecuador , Guyana , Peru , Venezuela , Suriname ( Berry et al. 2001 ). In Brazil it occurs in Amazonian forests ( Michelangeli & Reginato 2015 ). In the reserve, it occurs in “terra firme”, in secondary vegetation and trail edges, on clay soil and low organic matter. Comments: —This species is frequent in the reserve. It can be easily recognized by the asymmetrical leaf base.
