This species has Intermediate seeds. Seeds will tolerate drying to 5% moisture content. Once dried, seeds stored at -20ºC will remain viable for one year only. Survival in long-term storage under these conditions is not guaranteed.
The seeds of this species are oily, so sentitivity at low temperatures could be due to lipid crystallization. Handle the seeds carefully when re-warming, to allow the lipids to slowly melt.
Germinate on agar or sand at 25°C.
The seeds of this species do not display dormancy (based on other species in the same genus).
The fruit (6.25-9 cm) is oblate in shape, with a bright orange or red-orange skin. The pulp is deep orange in colour. The seeds are small and pointed at one end.
