Plant description

Annual or perennial herb, prostrate to erect much branched herb to 20 cm high. Leaves densely covered when young with colourless glistening transparent disc hairs, opposite or alternate, triangular, hastate or elliptic to 8 mm long. Inflorescence congested or lax, narrow-pyramidal or slender, exceeding the terminal leaves; flowers to 2 mm diameter, perianth with a felty indumentum of glistening vesicular hairs. Flowering in summer. Fruits are fruit enveloped by perianth; pericarp membranous to succulent. Seeds are black globular reniform seed to 1.5 mm diameter, almost smooth to slightly rugulose or striate. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between January and December. Collect fruit-heads that are maturing, turning pale brown firm black seeds inside. Place the fruits-heads in a tray and leave to dry for one to two weeks. Then gently rub the fruits with your fingers or a rubber bung to dislodge the seeds. Use a sieve to seperate the unwanted material. 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. This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat). Germination 89%, seed scarified (covering structure removed and seed coat chipped), on 1% w/v agar supplemented with 101mg/L potassium nitrate, 12/12 dark/light, 16°C. See http://data.kew.org/sid
