Uses

The wood (51 lb/cu ft) is used for building, construction, joinery, and vehicles. It is considered suitable for paper pulp (C.S.I.R., 1948–1976). The red gum or manna exuding from cracks in the bark is eaten eagerly by South African boys and has been used for making adhesives and birdlime (Watt and Breyer-Brandwijk, 1962). Eucalyptus manna, which exudes from punctures in summer months, is sometimes consumed. The essential oil shows the same antiviral (influenza) effect as that of E. dalrympleana (Vichkanova et al, 1973). Leaves inhibit Staphylococcus aureus.

Folk Medicine

The leafy twig decoction was used to bathe rheumatic limbs in South Africa.

Chemistry

Leaves contain 0.35–0.75% essential oil, of which 50–65% is cineol, 5% is pinene, and 10% is eudesmol. The "manna" contains arabinose, raffinose, dextrose, and sucrose. The bark contains 4.8–8% tannin, the kino 92.7% (Watt and Breyer-Brandwijk, 1962). The kino contains 7.1% moisture, 0.25% ash, and 92.7% catechin + tannin (C.S.I.R., 1948–1976).

Toxicity

The species is suspected to cause poisoning in koala bears, perhaps due to HCN (0.09% HCN has been reported) (Watt and Breyer-Brandwijk, 1962).

Description

Seedling phanerocotylar, the cotyledons reniform.

Germplasm

Reported from the Australian Center of Diversity, manna eucalyptus, or cvs thereof, is reported to tolerate more frost than most species of eucalypt. (2n = 22)

Distribution

Native to Southeastern Australia, but cultivated in Argentina, California, Hawaii, India, Peru, et al.

Ecology

No data available.

Harvesting

No data available.

Yields and Economics

At Calistoga, California, Standiford and Donaldson (1982) calculated 7.8 m3/ha/yr, equivalent to 3.2 cords or 20 million kcals/ha/yr.

Energy

NAS (1980a) suggested this as a promising firewood species. Webb et al. (1980) report wood yields of 10–30 m3/ha/yr.

Biotic Factors

Browne (1968) reports the following as affecting this species: (Fungi) Fomes robustus, F. setulosus, Inonotus chondromyelus, Phytophthora parasitica, Polyporus portentosus, P. zonatus. (Coleoptera) Entypotrachelus meyeri, Gonipterus scutellatus, Paropsis obsoleta, Phoracantha semipunctata, P. tricuspis. (Hemiptera) Eriococcus coriaceus. (Lepidoptera) Spilonota macropetana.
