Bartley, 1998a [BAR98A] Rio Branco is the name of several rivers and the name of a town in Acre.

Bartley 1997a, [BAR97A] The original Belem planting of RB clones comprised a mixture of types. This may account for the mixtures of genotypes in the CEPEC and CATIE collections with regard to RB 48 and RB 49. Any material distributed from CATIE should be identified as such to avoid confusion with clones from the primary source, which should be considered to be the correctly identified genotypes.
