Leaves 3 with the lower 2 similar, almost opposite, basal, with serrate margins, lanceolate to broad-lanceolate, to 8 cm long and 12 mm broad, with the inflorescence almost concealed between them, the upper leaf very short, lanceolate, just below or partly concealed within inflorescence. Inflorescence spike with 2-6 white flowers, females small, rounded, hidden at base of leaves, males larger more angular, exserted from leaf-base. Nectary 1 per tepal, a raised, transverse band, pale, anthers purple. This subspecies differ from the other subspecies found in the South Australia by the relatively shorter, broader, subopposite leaves, female spikes that do not extend beyond the leaves, and globose capsules. Flowering between June and July.

Orange globular seed to 2 mm diameter.
Embryo type:
Linear under-developed.
Seed collecting:
Collect mature capsules, those turning pale straw colour and containing hard brown seeds.
Seed cleaning:
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.
Seed viability:
From one collection, the seed viability was high, at 100%.
