Name derivation:
Haeckeria named after Dr G. Haecker (1789-1864), a German botanist. Cassiniiformis means shaped like the genus Cassinia; referring to the species habit and flower-heads.
Distribution:
Endemic to South Australia and found mainly on the Eyre peninsula.
Status:
Native. Rare in South Australia. More common after disturbance (e.g. fire, road work).
Plant description:
Short lived shrub to 1 m high with stems erect, rigid, sparsely branched, striate, minutely glandular-pubescent, pale-brown. Leaves spreading, linear, broadened at the base, obtuse, to 20 mm long and 0.8 mm wide, subglabrous to scabrous, gland-dotted, dark-green, with involute margins, sometimes in axillary fascicles on the older branchlets. Flower-heads dense, rounded, subglobular to hemispherical, to 5.5 cm diameter, terminating leafy branches with creamy-white flowers, corolla yellow. Flowering between October and March.
Fruit type:
Light cream, dense round daisy-head.
Seed type:
Brown cylindrical seed to 1.1 mm long and 0.5 mm wide, covered in fine tubercules.
Embryo type:
Spatulate.
Seed collecting:
Collect heads that are matured, cream and contain brown seeds.
Seed cleaning:
Place the heads in a tray for one to two week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a sieve to separate any 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 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
