Botanical Overview
Gum (Eucalyptus grandis) is a species in the Myrtaceae family. The myrtle family (Myrtaceae) includes trees and shrubs with opposite leaves that contain aromatic oil glands. The flowers are showy with numerous stamens, and the fruits are often fleshy berries or capsules. Many species produce essential oils with antiseptic and antimicrobial properties. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 29 compounds in this species, suggesting potential medicinal value.
General Description
At maturity, it reaches 50 metres (160 feet) tall, though the largest specimens can exceed 80 metres (260 feet) tall. It is found on coastal areas and sub-coastal ranges from Newcastle in New South Wales northwards to west of Daintree in Queensland, mainly on flat land and lower slopes, where it is the dominant tree of wet forests and on the margins of rainforests.
