Propagation Processing/Propagule Characteristics:
Seeds exhibit morpho-physiological dormancy.

Pre-Planting Propagule Treatments:
Seeds germinate at 23 C. Seeds were dry stored for an unspecified period of time in which the embryo afterripened prior to germination.
Seed germination is stimulated by the presence of charred wood or aqueous extracts of it: 89% increase in germination as compared to control.
