Here we go.

Eucalyptus is hard to spell. It is indigenous to Australia it is a Greek word meaning well covered and it's also known as a gum tree or scribbly gum because of the zig zag pattern it leaves on the tree trunk. scribbly gum is fun to say. Espesh if you say it like Crocodile Dundee.

WIKIPEDIA SAYS:
Eucalyptus has attracted attention from global development researchers and environmentalists. It is a fast-growing source of wood, its oil can be used for cleaning and functions as a natural insecticide, and it is sometimes used to drain swamps and thereby reduce the risk of malaria. Outside their natural ranges, eucalypts are both lauded for their beneficial economic impact on poor populations[3][4]:22 and derided for being invasive water-suckers,[5] leading to controversy over their total impact.

Did you know that you can drain a swamp with a eucalyptus tree?
Marvelous.
