Eucalypts

Eucalyptus / Corymbia spp.

Useful plants

Identify: Oil-dotted aromatic leaves; bark may be smooth, fibrous, stringy or flaky; woody capsule “gumnuts.”
Habitat: Australian forests, woodland and savanna; planted worldwide.
Season: Wood and bark year-round; flowers seasonal.
Field use: Hard wood for bows, spear shafts, handles and fuel; shedding bark can be tinder; hollow limbs may hold water only after careful inspection.
