SA Flora:
Flora of South Australia Edition 5
Name derivation:
Atriplex from the Latin 'atriplexum' meaning an orach, a saltbush; an Ancient Latin name for this plant. Stipitata from the Latin 'stipatatus' meaning stalked
Distribution:
Grows in mallee and woodland in drier parts of South Australia, north of the Murray River. Also found in all mainland states.
Status:
Native. Common in South Australia. Common in other states.
Plant description:
Erect shrub to 1m high. Leaves bitter tasting, narrow-elliptic to orbicular, to 20mm long with a scaly sheen on both surfaces. Male and female flowers on same plant. Inflorescence a spike; male flowers and females can also form panicles in the leaf axils. Flowering occurs all year, depending on rainfall.
Fruit type:
Pale-brown flat, papery fruit to 22mm long with a long stipe-like base; the upper part of the bracteoles flat, spreading, with recurved lobes, 10 mm wide.
Seed type:
Pale brown, reniform seed to 2mm long and 1.5mm wide.
Embryo type:
Peripheral.
Seed collecting:
Collect fruits that are starting to turn pale-brown, drying off and papery. Fruits can be collected directly from the bush or from the ground underneath
Seed cleaning:
Place the fruits in a tray and leave to dry for one to two weeks. No cleaning is required if only the fruits are collected. The seed can be stored in the fruit or can be clean further. Rub the fruit 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 90%.
