Name derivation:
Haegiela named after Laurence Arnold Robert Haegi (1952- ), an Australian botanist and plant collector. Tatei named after Ralph Tate (1840-1901), Professor of Natural Science, Adelaide.
Distribution:
Found along the coast from Fowlers Bay to the Coorong in South Australia, growing in saline, often gypseous habitats and often growing in samphire flats or low chenopod shrubland. Also found in Western Australia and Victoria.
Status:
Native. Rare in South Australia. Rare in the other states.
Plant description:
Small annual herb to 8 cm high with branches ascending to erect. Leaves ovate, lanceolate, obovate or linear, to 7 mm long and 2 mm wide, glabrous or cobwebbed. Flower-heads to 3 mm diameter with white-yellow flowers. Flowering between August and November.
Fruit type:
Pale brown head.
Seed type:
Brown ellipsoid to ovoid seed to 0.6 mm long and 0.3 mm wide, covered in fine tubercules.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect heads or whole plants that are pale brown or turning brown. Each head should have numerous tiny seeds.
Seed cleaning:
Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a fine sieve to separate the seeds from 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 high, at 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
