Name derivation:
Pandorea named after Pandora's box. Spach, the author of the name, is said to have been reminded of it when he saw the seed pod. Pandorana named after the Greek goddess Pandora in reference to the seed capsule's resemblance to Pandora's box.
Found in the far north-western corner of South Australia, growing in rocky areas along water courses. Also found in all states.
Native. Common in South Australia. Rare in Tasmania (Flinders Island). Uncommon in Western Australia. Common in the other states.
Plant description:
Glabrous shrub to 6 m high, with many ascending wiry stems and other branches twining around them. Leaflets in 2-5 pairs, narrow-lanceolate, to 50 mm long and 10 mm wide, broader and sometimes longer outside arid regions. Flower-spikes several to many-flowered with funnel-shaped flowers, cream with red-brown markings inside the broad open tube. Flowering between August to November.
Fruit type:
Dark brown oblong-ellipsoid, somewhat compressed, capsule to 70 mm long and 20 mm wide, with thick woody valves.
Seed type:
Orange, semi-flat ovoid seed to 10 mm long and 7 mm wide, with papery wing.
Seed collecting:
Collect capsules that are maturing, turning brown and contain hard, orange seeds inside or capsules that are split but have not released their seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks or until they split. Then break and shake the capsules gently by hand 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 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
