Distribution

Notes

No flowers or fruits have been seen from the Guianas.
The collection Polak 316 consists of fallen leaves and fruits as well as seedlings, all found under the parent tree. It is probably B. pallidovirens, but the material does not permit certainty. The species could well occur in the Guianas on distributional grounds.
