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. Fruits are dark red to black ovoid-oblong fruit to 12 mm long and 12 mm, fleshy, shiny. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between January and December. Collect mature fruits when skin begins to crinkle, either from the tree directly or off the ground beneath it. 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. 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
