Characteristics

Spreading to erect shrub to 1.5 m high, dioecious or monoecious. Leaves thin, shortly petiolate, narrowly elliptic to elliptic or ovate, 2.5–4 cm long, entire, with scurfy sheen on both surfaces. Male flowers in dense glomerules mostly 5–7 mm diam. forming interrupted or continuous spikes or panicles. Female flowers in clusters axillary to upper foliage leaves. Fruiting bracteoles subsessile or shortly stipitate; stipe turbinate, hard; bracteoles ovoid to broadly deltoid or rhomboid, 6–10 mm long and wide, united towards base, often hard and swollen in centre, thin and entire on margin, smooth or with a verrucose appendage on one or both sides. Seed circular; radicle lateral, erect. [See also Green (1994).]

Low, spreading, dense, much-branched, dioecious subshrub, densely covered with silvery grey scales, with main stems often slightly horizontal and rather slender. Shoots strongly angular, with scattered glandular hairs. Lvs subsessile, 1-2.7 × 2-4 mm, linear or oblong-linear, entire; base attenuate; apex obtuse or nearly so. ♂ fls in continuous or interrupted terminal spikes or panicles. ♀ fls solitary or few in axillary clusters, monomorphic; bracteoles united for c. ⅓ length, to 3.5 × 3.5 mm at fruiting, often smaller, broad-ovate to rhombic, entire; united part becoming indurate; free parts becoming ± swollen, spongy; apex obtuse. Seed c. 2 mm diam., circular, with radicles protruding.
A dense small shrub. It grows 60-90 cm high. It can be 2 m high. It can spread 1.8-6 m wide. Stems can form roots at the nodes. The leaves are pale grey-blue. The leaves are 2.5-4 cm long and have a blunt tip. Male and female plants occur on separate plants. Male flowers are lumpy brown spikes at the tips of plants. Female flowers are single or in small clusters in the axils of leaves. Female plants produce clusters of small grey pods. The pods are 6-10 mm long. They are triangle shaped.
Perennial, monoecious or dioecious shrub, 1-5 m high, grey-to white-squamous (scaly). Leaves 10-80 x 5-30 mm, alternate, elliptic-ovate to linear-lanceolate, mostly entire, leathery. Male and female flowers mixed in terminal, pyramidal panicles. Fruiting bracts 4-15 x 4-11 mm, deltoid-elliptic to spathulate, fused up to broadest part, entire or slightly toothed, glabrous or hump-tubercled on back (under side), ± completely spongy, at length hardening.
