Name derivation:
|
Billardiera named after Jacques Julien de La Billardiere (1755-1834), a 19th century French botanist who visited Western Australia and Tasmania with D'Entrecasteaux expedition and named many new plant species. Versicolor from Latin meaning with various colour; referring to the changing colour as the flower aged. |
Distribution:
|
Found in the southern part of South Australia from the Flinders Ranges south to the upper South-east. Also found in New South Wales and Victoria. |
Status:
|
Native. Common in South Australia. Common in the other states. |
Plant description:
|
Twining perennial shrub with stems to a few metres long. Leaves lanceolate to 62 mm long and 17 mm wide, upper surface glabrous, lower surface sparsely pilose. Flowers initially white, cream-coloured or pale yellow, with spreading mauve-red blotches from throat with age, bell-shaped appearing in September to December. |
Fruit type:
|
Cylindrical berry to 25 mm long and 8 mm wide, green and hard when immature and soft when ripe. |
Seed type:
|
Brown flat reniform seeds to 2 mm long and 2 mm wide, covered in deep wrinkles. |
Embryo type:
|
Linear underdeveloped. |
Seed collecting:
|
Pick mature fruits by hand, those that are soft or have brown seeds inside. |
Seed cleaning:
|
Clean ripe fruits as soon as possible as it will go hard if left to dry too long. Rub the fruits in water with your hands to dislodge the seeds from the fruit. Pour the mixture into a sieve to separate the seeds from the flesh. Place the wet seeds in a tray lined with paper and leave to dry for 1 to 2 days. 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 three collections, the seed viability were high, ranging from 95% to 100%. |
Seed germination:
|
This species has physiological dormancy that need to be overcome for the seed to germinate. |
