SA Flora:
Flora of South Australia Edition 5
Name derivation:
Tecticornia from the Latin 'tectum' meaning roof (referring to the bracts) and 'cornu' meaning horn; alluding to its relationship to Salicornia. Indica meaning of or from India. Leiostachya from the Greek 'leios' meaning smooth and 'stachya' suffix meaning flower spike.
Distribution:
Found across South Australia, growing on margins of saline water bodies, often associated with sand over calcrete. Also found in all mainland States.
Status:
Native. Common in South Australia. Common in the states.
Plant description:
Stout erect perennial, with fleshy cylindrical flower spikes.
Fruit type:
Corky or spongy fruiting spikes containing compressed segments layered with hard pyramidal shaped fruits.
Seed type:
Pale brown ovoid to circular seed to 1.5 mm long, with a membranous outer covering.
Embryo type:
Peripheral.
Seed collecting:
Collect spikes that are dry and brown. Seeds are hidden in the segments of the stems.
Seed cleaning:
Place the spikes in a tray and leave to dry for 1-2 weeks. Then rub the spikes gently with your hands or a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Be careful as the seeds are very small. 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 low at 49%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
