Plant description
Scrambling or often climbing perennial with slender stems slender to 1 m long, usually glabrous. Leaves and stipules about equal, in whorls of 4 at the base, with stipules becoming minute or absent on flowering branches so that the leaves are opposite, linear or linear-elliptic, to 15 mm long, rarely up to 35 mm long on lower branches. Inflorescences at terminal with 1-3 small clusters, each with up to 9 yellowish-green flowers. Flowering between September and March. Fruits are in two, reddish, globular to 3 mm diameter.
Seed collection and propagation
Collect seeds between November and June. Collect maturing fruits by picking off the clusters that are fat and turning reddish-brown or break off stems with numerous fruit clusters. Place the fruits in a tray and leave to dry for one to two weeks. Then rub the fruits with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
