A highly variable species with eight subspecies recognises in other states but not South Australia, where the subspecies tend to intergrade. Dioecious, erect or decumbent shrub to 1 m high. Leaves to 25 mm long and 15 mm wide, elliptic to oblong or obovate, acute, obtuse or rounded, usually entire, attenuate at the base, sparsely to densely scaly. Male flowers in dense clusters arranged in a terminal spike or panicle and female flowers with 2 to many in the upper axils. Flowering throughout the year. Fruiting bracteoles sessile or with a very short pedicel; valves free or fused to above the seed, orbicular to ovate-triangular or rhomboid, obtuse to mucronate, to 13 mm long and wide, entire or dentate towards the apex, cuneate to cordate at the base; appendages thin-walled and bladder-like, attached to the base of the valves or fused to one another below the bracteoles or to the bracteole margin, sometimes absent.
Seed collection and propagation
Collect seeds between January and December. Collect ripe straw coloured fruits, check that they contain viable seeds. Fruits can be collected directly from the bush or from the ground underneath. Remove twigs and other plant material. Place the fruits in a tray and leave to dry for one to two weeks. No cleaning is required if only the fruits are collected. The seed can be stored in the fruit or can be cleaned further. Rub the fruit 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 can be high but seed availability can be low.
