Scientific name: Eucalyptus pulverulenta
Profile last updated:
21 Sep 2021
Description
The Silver-leafed Gum is a distinctive, straggly mallee or small tree that grows to about 10 m tall. The bark is smooth and grey or bronze, shedding in long strips. The tree is distinctive because of its round, stalkless, paired, waxy, blue-green juvenile leaves, 5 cm long and wide, which are characteristically retained on mature plants. Only rarely are adult leaves produced, these being stalked, lance-shaped and up to 10 cm x 2 cm. The buds occur in clusters of 3 and the large cream-coloured flowers are produced from September to November. The flowers are followed by large gumnuts.
Distribution
The Silver-leafed Gum is found in two quite separate areas, the Lithgow to Bathurst area and the Monaro (Bredbo to Bombala).
Habitat and ecology
- Grows in shallow soils as an understorey plant in open forest, typically dominated by Brittle Gum (Eucalyptus mannifera), Red Stringybark (E. macrorhynca), Broad-leafed Peppermint (E. dives), Silvertop Ash (E. sieberi) and Apple Box (E. bridgesiana).

Threats
- Lack of regeneration through grazing pressure.
- At risk from catastrophic events because of small number of extant populations and low number of plants.
- Browsing and trampling by domestic stock and feral goats.
- Habitat loss and fragmentation.
- Maintenance and/or widening of fire trails causes major disturbance.
- Inhibited recruitment, and threats to seedlings via non-target impacts from weed control measures; chemical spraying and/or physical removal.
- Browse young plants and inhibit recruitment.
- Current or potential future land management practices do not support conservation.
- Blackberries and Serrated Tussock are two weed species that are known to be close to a few populations. Most populations remain relatively weed free due to the low fertility soils in which the species generally grows.

Activities to assist this species
- Encourage regeneration by fencing remnants, controlling stock grazing and undertaking supplementary planting or direct sowing of this species, if necessary.
- Conduct further survey in potential habitat to look for other populations.
