SA Flora:
Flora of South Australia Edition 5
Name derivation:
'Maireana' after the 19th certury belgium botanist Adolphe Lemaire and Latin 'brevis' short, 'folia' leaves
Distribution:
Usually found on slightly saline soil, often recorded in open mallee. Distributed through the Eyre, Yorke and Fleurieu Peninsulas, Murraylands and Flinders Ranges.
Status:
Native. Common in Victoria, New South Wales and the SW of Western Australia. Mostly recorded in South Australia.
Plant description:
Erect, short-lived perennial shrub to 1.5 m high. Leaves alternate, fleshy, obovoid to narrow-fusiform, 2-5 mm long, glabrous. Flowers solitary, glabrous apart from the woolly ciliate lobes. Flowering January - October.
Fruit type:
Fruiting perianth glabrous; tube shallowly hemisperhical, thin-walled, 2 mm in diameter; wings 5, horizontal, thin, fan-shaped, 2-3 mm long, with delicate brown venation when dry; perianth lobes thick and fleshy, sharply demarcated from the wings.
Seed type:
Circular, brown, convex seeds
Embryo type:
Peripheral
Seed collecting:
Collect seeds when fruits are brown and papery. Check inside several fruits for the presence of well developed seed before making a collection. Strip or shake fruiting branches into a container.
Seed cleaning:
Remove twigs and other plant material.
Seed viability:
65% and 84% viability in two collections
Seed germination:
Germination levels varied from 12% to 86%.
