Name derivation:
Ipomoea from the Greek 'ips' meaning a worm (mistakenly supposed by Linnaeus to mean the bindweed) and 'homoios' meaning like; referring to its twining habit. Lonchophylla from the Greek 'lonchos' meaning spear-shaped and 'phyllon' meaning a leaf.
Distribution:
Found in the north-eastern part of South Australia, growing on clay soils in tussock grasslands. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
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.
Fruit type:
Brown globular capsule, with a persistent style base and splitting longitudinally into 4 valves.
Seed type:
Dark brown to black sectoroid seed to 4.5 mm long and 4 mm wide, with dense hairs.
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 viability:
From one collection, the seed viability was high, at 95%.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
