Its leaves are one of the favoured foods of the koala. The tree's common name comes from its bark, which takes a greyish cast at about one year of age (see photograph). On most trees this bark is partly shed, revealing a bare and slightly orange or brown tinted smooth surface. The white flowers appear over the summer. |

In large doses, oil of eucalyptus, like so many essential oils has caused fatalities from intestinal irritation; Death is reported from ingestion of 4 - 24 ml of essential oils, but recoveries are also reported for the same amount; Symptoms include gastroenteric burning and irritation, nausea, vomiting, diarrhoea, oxygen deficiency, ,weakness, dizziness, stupor, difficult respiration, delirium, paralysis, convulsions, and death, usually due to respiratory failure; | | Leaf Type [2] | Evergreen | | Pollinators [2] | Bees | | Specific Gravity [3] | 0.908 | | Structure [2] | Tree | | | Height [2] | 98 feet (30 m) |
