Plant description
Annual or rarely biennial herb to 50 cm high, at least base of plants covered in irregularly branched or stellate hairs. Basal leaves to 10 cm long, pinnately lobed, lobes lanceolate to linear, toothed or entire, stem leaves to 10 cm long, pinnately- or 3-lobed to entire and thread-like. Inflorescence a terminal spike with chocolate-brown to olive-green. Flowering between July and September. Fruits are brown oblong to slightly obovoid pod to 7 mm long and 2 mm wide. Seeds are brown ovoid seed to 1.2 mm long and 0.8 mm wide. Seed embryo type is bent.
Seed collection and propagation
Collect seeds between September and November. Collect maturing pods those turning pale brown with brown seeds inside. Be gentle with the pods as they split open easily. Place the pods in a tray and cover with paper to prevent seeds from popping out and leave to dry for a week. Then rub the dried pods gently by hand to dislodge the seeds. Use a sieve to separate 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. From one collection, the seed viability was high, at 100%.
