SA Flora:
Flora of South Australia Edition 5
Name derivation:
Chenopodium from the Greek 'chen' meaning goose and 'pod' meaning foot; referring to the shape of the leaves in some species. Nitrariaceum meaning resemblance to the genus Nitraria; alluding to the species habit.
Distribution:
Found across the north-eastern part of South Australia, growing on heavy alluvial soils, chiefly by the Murray River and its associated floodplains. Also found in all mainland states.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Divaricately branched spinescent shrub to 2 m high. Leaves alternate, frequently clustered, spathulate to linear, to 5 cm long and 5 mm wide, sparsely covered with collapsed vesicular hairs. Inflorescence a terminal spinescent panicle to 15 cm long or reduced to a short spike, flowers polygamous, clustered. Flowering between March and October.
Fruit type:
Fruit enveloped by the perianth, dry; pericarp membranous, white, free, pubescent above
Seed type:
Red-brown depressed-globular reniform seed to 1.2 mm diameter.
Embryo type:
Peripheral.
Seed collecting:
Collect fruit-heads that are maturing, turning pale brown firm black seeds inside.
Seed cleaning:
Place the fruits-heads in a tray and leave to dry for one to two weeks. Then gently rub the fruits with your fingers or a rubber bung to dislodge the seeds. Use a sieve to seperate the unwanted material. Store the seeds with a desicant 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 88%.
