Name derivation:
Acacia from the Greek 'akakia' and derived from 'ake' or 'akis 'meaning a sharp point or thorn and 'akazo' meaning to sharpen. Farinosa from the Latin 'farinosus' meaning covered with mealiness or powdery, referring to the young stems and peduncles which are covered with a white mealiness.
Found in the southern part of South Australia, on the Eyre Peninsula, Yorke Peninsula, Kangaroo Island, southern Mount Lofty Ra, Murray and South-Eastern regions, growing in woodland to open scrub on a variety of soils. Also found in Victoria.
Native. Common in South Australia. Uncommon in Victoria.
Plant description:
Small, much-branching and spreading shrub to 2 m high, usually covered with a hoary white mealiness on young branchlets. Phyllodes oblanceolate to linear-oblanceolate rigid, slightly curved, thick-fleshy, to 70 mm long and 6 mm wide. Inflorescence axillary in clusters of 2-4 yellow globular flowerheads. Flowering between August and October.
Fruit type:
Brown curled and twisted pod to 60 mm long and 3 mm wide, with margins thickened, slightly constricted between seeds.
Embryo type:
Seed collecting:
Collect mature pods that are turning brown, with hard, dark seeds inside.
Seed cleaning:
Place the pods in a tray and leave to dry for 1-2 weeks or until the pods begin to split. Then rub the dried pods to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desicant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
