Name derivation:

Native. Rare in South Australia. Common in Western Australia.
Plant description:
Erect glabrous shrub to 50 cm tall, with many branches arising from the base. Leaves inserted spirally on short but distinct stalk, oblong-cuneate, to 15 mm long and 7 mm wide, mucronulate, flat, green-glaucous. Flowers on slender stalk, female flowers solitary, with or without 2 or 3 males in the same axils. Male perianth-segments 6 rarely 5, petal-like, ovate, pink, bordered with white, anthers and filaments free, cells dehiscing lengthwise. Female perianth larger than in the males, the segments broadly ovate, nearly concealing the capsule, styles free or very shortly united at the base. Flowering between May and October.
Fruit type:
Green globular capsule to 5 mm diameter.
Seed type:
Brown sectoroid seed to 3 mm long and 2.2 mm wide, smooth with longitudinally striate with darker lines. 
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect individually or break off short fruiting stems with fat, brown capsules with hard dark seed. Slightly green capsules can be collected if the seeds are dark and hard.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then gently rub the capsules with a rubber bung to dislodge the seeds. Use a sieves 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:
Seed viability can be variable and seeds. From one collection, the seed viability was high, at 85%.
