Endemic to Australia, widespread in more inland parts of WA, NT, NEQ and CEQ. Altitudinal range from near sea level to 500 m. Usually grows in open forest but also found in monsoon forest and similar closed forest communities.

Natural History & Notes

Has potential as a street tree for dry areas. Produces red flowers.

Aboriginal usage: The branches were used to make windbreaks in the dry season. They also make excellent smokeless firewood. Aboriginal people ate the sweet gum and sucked the nectar from the flowers. They also used the bark and wood to treat headache, as an antiseptic and as a remedy for fever. Kenneally et al. (1995).
