About
Eucalyptus sideroxylon, commonly known as mugga ironbark, or red ironbark is a small to medium-sized tree that is endemic to eastern Australia. It has dark, deeply furrowed ironbark, lance-shaped adult leaves, flower buds in groups of seven, white, red, pink or creamy yellow flowers and cup-shaped to shortened spherical fruit.
Safety
Molecules produced by plants in case of pathogens attacks are called phytoalexins. Such compounds can be implied in the hypersensitive response of plants. High levels of polyphenols (stilbenoids and ellagitannins) in E. sideroxylon wood can explain its natural preservation against rot.
Where it grows
Mugga ironbark is widespread and often abundant in woodland from south-eastern Queensland through New South Wales to Victoria. Subspecies improcera is only known from the Barakula State Forest north-northwest of Chinchilla.
Uses
The leaves are used in the production of cineole based eucalyptus oil.
