SA Census:
Census of South Australian plants (external link)     [genus Eremophila]
Name derivation:
Eremophila from the Greek 'eremophiles' meaning loving solitude or desert; alluding to the habitat. Longifolia from Latin meaning with long leaves.
Distribution:
Found across much of South Australia except for Kangaroo Island and the South-east, growing in a variety of communities on most soil types, widespread on the plains and in the ranges. Also found in all mainland states.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Grey to green shrub or small tree 8 m tall, frequently root-suckering and forming dense stands. Leaves alternate, linear-lanceolate, to 200 mm long and 14 mm wide, acuminate often with a hooked tip, pubescent to tomentose. Flowers in clusters of 1–5 in axils with red to brownish red, spotted or unspotted tubular flowers. Flowering all year round.
Fruit type:
Dark red to black ovoid-oblong fruit to 12 mm long and 12 mm, fleshy, shiny.
Seed type:
No information available.
Embryo type:
Linear fully developed.
Seed collecting:
Collect mature fruits when skin begins to crinkle, either from the tree directly or off the ground beneath it.
Seed cleaning:
Soak fruit with 1% pectinase for 24 hours, then rub gently through sieves to remove unwanted material. Rub and change the water a few times until all the fresh are removed. Leave the cleaned seed to dry and then store with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
Germination 10%, seed sterilised (10% Demestos solution for 5min), then scarified (covering structure removed) on 1% w/v agar, 12/12 dark/light, 31°C. See http://data.kew.org.sid
