Plant description
Scrambling, climbing perennial with woody stems to 4 m. Leaves broadly lanceolate-hastate; obtuse or shortly acuminate, to 3 cm long and 1 cm wide. Flowers green. Flowering throughout the year. Fruits are fleshy ovoid fruit with persisting perianth. Fruits turn from green to yellow-orange when ripe. Seeds are black ellipsoid seed to 4 mm long and 3 mm wide, with lateral furrows and a wrinkled surface. Seed embryo type is peripheral.
Seed collection and propagation
Collect seeds between January and December. Collect ripening fruits that are turning yellow and contain a hard black seed. Place fruits in a bucket of water and leave to soak overnight, then rub the fruit to remove the flesh. Rub and change the water a few times until all the fresh is removed. Leave the cleaned seed to dry and then store with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From three collections, the seed viability was average to high, ranging from 75% to 100%. Seeds are non-dormant, viable seed should germinate readily.
