Plant description

Decumbent shrub to 3 m diameter. Leaves narrow-elliptic, acute, entire, glabrous above and white scaly below with leaf blade to 30 mm long and 8 mm wide. Male flowers in dense distinct or continuous globose clusters; female flowers few in upper axils or clusters along terminal leafless spikes. This subspecies differs from the other subspecies found in South Australia by being decumbent with leaves that are glabrous above, compared to Atriplex paluoda ssp. cordata which is an erect shrub with leaves that are scaly all over. Flowering throughout the year. Fruiting bracteoles sessile, fused and often slightly fleshy near base, green or somewhat mealy, triangular or broadly ovate, truncate or slightly cordate at base, entire or with a few teeth above midway, to 10 mm long and wide, dorsal appendages absent. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between January and December. Collect fruits that are starting to dry or and turn brown. Fruits can be collected directly from the bush or from the ground underneath 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.
