Plant description
Dioecious herb to 20 cm high. Leaves 3, alternate, the lowest leaf linear-lanceolate, elongate, to 15 cm long and 5 mm wide, erect, middle leaf similar or shorter and with an inflated base, upper leaf just below the inflorescence, somewhat ovate and swollen to 2 cm long, as wide as long, not elongated as in the other leaves. Inflorescence spike with 1–6, unisexual, rarely bisexual flowers, female flowers distinctly smaller, male flowers white or cream, female flowers often turning pink with age, tepals more rounded, nectary a single continuous horizontal band of purple, stamens on male plants only, white, anther purple, ovary ovoid, often turning purple. This subspecies differ from the other two subspecies found in South Australia by the short, ovate uppermost leaf that lacks an elongated apex, and pink-edged tepals. Flowering between June and September, usually earlier than W. dioica ssp. dioica where the two grow together. Fruits are brown papery ovoid capsule containing many seeds. Seed embryo type is linear under-developed.
Seed collection and propagation
Collect seeds between August and November. Collect mature capsules, those turning pale straw colour and containing hard brown seeds. Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules 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.
