Plant description

Shrubby perennial to 1m high; branches decumbent to erect; tomentose. Leaves semi-terete, succulent to approximately 15mm long; villous. Inconspicous small flowers; solitary, emerging from the axis of the leaf and stem. Flowering May-November. Fruits are fruiting perianth depressed-globular, flat to deeply sunken in the centre; wing absent or crown-like and incurved; lobes glabrous but ciliolate to pubescent. Approximately 5mm in diameter; green, yellow or red (drying brown to black). Seeds are seeds are black/brown and disc shaped up to 1.5 mm diameter, with overlapping embryo tip sometimes forming a small beak. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between December and April. Collect the fruits by running gloved fingers through branches to remove mature or drying fruits. Collect when fruit is red and seed inside is brown and firm. Soak the fruit in 1% pectinase and water solution for at least 4 hours. Then gently rub the soaked fruits through a sieve to remove the fleshy and leave the remaining seeds to dry. Store the dried fruit heads with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Germination 100%, seed scarified (covering structure removed) on 1% w/v agar, 12/12 dark/light, 23°C/9°C. See http://data.kew.org/sid
