Census of South Australian plants (external link)     [genus Convolvulus]
SA Flora:
Flora of South Australia Edition 5
Name derivation:
Convolvulus the Latin name of some bindweed, from 'convolvere' meaning to roll together or entwine. Remotus means remote (as in remote places, scattered); alluding to the species distribution or habitat.
Distribution:
Found across most part of South Australia, growing on a wide variety of soil types from clays through loams to sands, in chenopod shrublands Acacia shrublands, open mallee woodlands and heaths and on sandhills iand drainage lines. Also found in all mainly states.
Status:
Native. Common in South Australia. Uncommon in Queensland. Common in the other states.
Plant description:
Herb with trailing and twining stems. Leaves ovate to oblong, hastate or sagittate, to 80 mm long and 40 mm wide, acute to rounded, mucronulate, base cordate, basal lobes entire or occasionally with a secondary pair of lobes, terminal lobe entire, sparsely to densely hairy. Flower-spike a cymose, with 1–3 funnel-shaped pink flowers. Flowering between August and December.
Fruit type:
Brown globular capsule to 7 mm diameter.
Seed type:
Dark brown to black secteroid seed, with a slight rugose surface.
Embryo type:
Folded.
Seed collecting:
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.
Seed cleaning:
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.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
