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.  
Distribution:
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.
Status:
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.
