Name derivation:
Anemocarpa from the Greek 'anema' meaning without a thread and 'carpos' meaning fruit; referring to the absence of hairs on the achenes. Saxatilis from Latin for rocky; alluding to where the species is found, growing among rocks.  
Found in the north central part in South Australia, growing among rocks and on sand hills. Also found in the Northern Territory, Queensland and New South Wales.
Native. Common in South Australia. Uncommon in Queensland and New South Wales. Common in the Northern Territory.
Plant description:
Much-branched woody and woolly perennial herb to 40 cm high. Leaves sessile, oblong to narrow-obovate to 30 mm long and 8 mm wide, apex acute, margins crinkly. Flower-heads terminal on slender naked peduncles to 8 cm long, heads to 20 mm diameter, involucre spreading from base, white to pale pink. Flowering between May and September.
Fruit type:
Dry daisy head to 20 mm wide.
Seed type:
Narrow cylindrical brown achene to 2 mm long and less than 0.5 mm wide with a feathery pappus to 6 mm long.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect heads that are round and brown.
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. Viable seeds will be long, fat and hard. 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 30%. This may reflect the low seed set of daisies or maybe due to the timing of the seed collection.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
