Glabrous to sparsely hairy annual herb with trailing stems. Leaves ovate to ovate-lanceolate, to 10 cm long and 4 cm wide, acute to obtuse, mucronate, base attenuate to barely truncate. Inflorescence axillary with a single small white funnel-shaped flower. Flowers throughout the year but mainly between November and June. Fruits are brown globular capsule, with a persistent style base and splitting longitudinally into 4 valves. Seeds are dark brown to black sectoroid seed to 4.5 mm long and 4 mm wide, with dense hairs. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between January and December. Collect capsules that are maturing, turning brown and contain hard seeds inside. Capsules can be opened or unopened and some seed can be collected from the ground under the plant. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or 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. From one collection, the seed viability was high, at 95%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
