- Observation Port Elizabeth seeds retained 100% viability after 12 weeks at 6 °C.
- Observation St Lucia seeds had died after 38 days at 3 °C.
- Observation St Lucia seeds retained 100% viability after 38 days at 6° and 16 °C.

- Observation Tanzanian seeds retained 35% viability after nine days at 16 °C.
- Observation Protein synthesis rate decreased in stored seed axes.
- Observation Solute leakage increased in stored seed axes.
- Mechanism Reduced protein synthesis and greater leakage implied breakdown of metabolic activity during storage.
- Observation Port Elizabeth seeds tolerated slow drying.
- Observation Port Elizabeth seeds were suggested to be minimally recalcitrant.
- Observation St Lucia seed axes lost ultrastructural integrity at 3 °C.
- Observation Tanzanian seed axes lost ultrastructural integrity at 3 °C.
- Observation Port Elizabeth seed axes showed no ultrastructural deterioration during relatively prolonged storage.
- Observation Temperate Port Elizabeth seeds tolerated chilling temperatures well.
- Observation St Lucia seeds did not tolerate chilling temperatures well.
- Observation Tanzanian seeds did not tolerate chilling temperatures well.
- Observation The authors suggested that the sampled seed groups may not all belong to one species.
