Census of South Australian plants (external link)     [genus Parietaria]
Name derivation:
Parietaria from the Latin 'paries' meaning a wall; referring to some species growing on old walls. The name was used by the Roman naturalist and philosopher Pliny. Debilis from Latin meaning weak, frail, small; alluding to its habit.
Distribution:
Found in the southern and the far north-western parts of South Australia, growing in shaded habitats under shrubs. Also found in all states.
Status:
Native. Common in South Australia. Rare in Tasmania. Uncommon in the Northern Territory and Queensland. Common in the other states.
Plant description:
Annual herb to 30 cm high, not woody at base, stems erect, sometimes ascending, sometimes rooting at nodes, densely covered in curved and hooked hairs. Leaf-blade ovate to broadly ovate, to 45 mm long and 18 mm wide, more or less delicate, 3-nerved, base subcordate, cuneate or truncate, apex blunt or obtusely acuminate, midvein straight, the lateral veins with delicate tertiary veins. Inflorescence a cluster of 2–10 small green flowers. Flowering between August and November.
Fruit type:
Long brown capsule in axis of leaves with one seed.
Seed type:
Shiny dark brown ovoid seed to 1.5 mm long and 0.7 mm wide.
Seed collecting:
Collect capsules that are turning brown by break off stems with numerous mature capsules.
Seed cleaning:
Place the plant material in a tray and leave to dry for one to two weeks. Then rub the plant with a rubber bung to dislodge the seeds. Use a sieve to separate any 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.
