Name derivation:
Tetragonia from the Greek 'tetra' meaning four and 'gonia' meaning angle; alluding to the 4-angled fruit of some species. Moorei named after C.W.E. Moore who recognised the distinctiveness of this species and whose ecological studies and abundant collections have enriched the Australian National Herbarium.
Distribution:
Found in the eastern side of South Australia, growing in a variety of habitats, sand dunes and swales, and on both light and heavy-textured soils from red sands to grey cracking clays, particularly in areas subject to periodic inundation. Also found in Western Australia, Queensland, New South Wales and Victoria.
Status:
Native. Common in South Australia. Uncommon in Victoria. Common in the other states.
Plant description:
Succulent annual with slender taproot, erect, prostrate or decumbent with young shoots pubescent. Leaves narrow- to broad-ovate, elliptic or rhombic, to 10 cm long and 5 cm wide, petiolate. Flowers yellow-green, solitary in the axils. Flowering between September and November.
Fruit type:
Yellow black ovoid woody fruit with 2 claw-like projections.
Embryo type:
Peripheral.
Seed collecting:
Collect fruits that are maturing, turning black.
Seed cleaning:
Place the capsules in a tray and leave to dry for at least a week. No further cleaning is required. 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 100%.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate.
