Joseph Banks and Plants
Brief Information about Joseph
Banks
•
•
•
•
Also known as Sir Joseph Banks for his work
Is famous for being a naturalist and a botanist
Took part in Captain James Cook First Voyage
Introduced different plants to the western world such
as eucalyptus, acacia, mimosa and named after
him, Banksia. Approximately 80 species of plants
bear Banks's name
• Discovered 1300 new species of plants
• Famous quote by Joseph Banks: 'collection of
plants was . . . grown so immensely large that it was
necessary that some extraordinary care should be
taken of them least they should spoil . . .'
Four Plants in Focus today:
•
•
•
•
Eucalyptus
Acacia
Mimosa
Banksia
Eucalyptus……
• Eucalyptus, from the Greek words eu
-, well, and kaluptos, cover, meaning
"well-covered", describes the operculum
• More than 700 species of Eucalyptus, mostly native to Australia, and
a very small number are found in adjacent areas of New Guinea and
Indonesia
• Takes the form of a low shrub or a very large tree
• Eucalyptus oil is the most common use of eucalyptus and is readily
steam distilled from the leaves and can be used for cleaning and as
an industrial solvent, as an antiseptic, for deodorising, and in very
small quantities in food supplements, especially sweets, cough
drops, toothpastes and decongestants.
• Can also be used for honey. The nectar of some eucalypts produces
high-quality monofloral honey.
• Eucalypt wood is also commonly used to make digeridoos, a
traditional Australian Aboriginal wind instrument.
Acacia…..
• Acacia is the Arabic name for
gum.
• There are over 1300 species of
Acacias. About 960 Acacias are native to Australia.
• Acacia seeds are often
used for food and a variety of other products.
• Acacia species have possible uses in folk medicine.
• The ancient Egyptians used Acacia in paints.
• Acacias are linked to the mimosa family (you will
discover this in the next slide)
Mimosa……
• Mimosa comes from the
Greek word mimos, meaning ‘mimic’.
• There are 400 species of herbs and shrubs within this
family.
• This plant is capable of rapid movement and when you
touch it, the leaves of the plant closes quickly.
• They come in a cluster of many individual mimosas, not
individually.
• The mimosa tree bark can be used as a herbal medicine.
• It is a medicinal plant for colds, fever, toothaches, eye
medicine, snakebite, weak heart and diarrhoea.
• Mimosa can be used for timber in countries such as
Vietnam and Thailand
• Used to feed animals because it has a high protein
content.
Banksia…..
• Named after Joseph Banks
• Only 170 species.
• These Australian wildflowers and popular garden plants are easily
recognised by their characteristic flower spikes and fruiting "cones"
and heads.
• These plants are heavy producers of nectars and have the following
animals rely on them for survival - birds, bats, rats, possums,
stingless bees and a host of invertebrates
• They are becoming rare and endangered due to land clearing,
frequent burning and diseases.
• Popular garden plants in Australia because of their large, showy
flower heads, and because the large amounts of nectar they
produce attracts birds and small mammals.
• Occasionally used for ornamental purposes in wood turning and
cabinet paneling because the banksia wood is often red in colour.
