Known Hazards
Where to Find It
It is a tropical plant. It grows in northern Australia. It suits medium to heavy soils. It requires an open sunny position. It can withstand wind, drought and frost. It is mostly in areas with a rainfall from 50 to 65 mm mostly in summer with long droughts in between.

How to Identify
A shrub or small tree. It grows 5 m tall. There are prickles along the stem. The leaves are twice divided and there are 8-18 pairs of pinnae. There are up to 50 pairs of pinnules on each pinnae. The flowers are yellow. They are in large clusters at the ends of branches. The pods are flattened.
How to Grow
It is grown from seed. The seed needs to be treated to break the hard seed coat. Normally this is by putting the seeds in very hot water and letting the water cool down overnight then planting the seeds immediately.
Propagation: Unlike most acacias, the seeds of this species have a thin seedcoat and will usually germinate without pretreatment. The use of boiling water to hasten germination can be harmful. Acacia seeds that have matured fully on the bush and have been properly dried have a hard seed coat and can be stored in closed containers without deterioration for 5 - 10 years or more in dry conditions at ambient temperatures. It is best to remove the aril, which attracts weevils and can lead to moulds forming. The arils are easilyremoved by placing the seeds in water and rubbing them between the hands, then drying the seeds and winnowing them.
Medicinal Uses
The bark of all Acacia species contains greater or lesser quantities of tannins and are astringent. Astringents are often used medicinally - taken internally, for example. they are used in the treatment of diarrhoea and dysentery, and can also be helpful in cases of internal bleeding. Applied externally, often as a wash, they are used to treat wounds and other skin problems, haemorrhoids, perspiring feet, some eye problems, as a mouth wash etc. Many Acacia trees also yield greater or lesser quantities of a gum from the trunk and stems. This is sometimes taken internally in the treatment of diarrhoea and haemorrhoids.
Other Uses
The heartwood is a dark reddish-brown to almost black; it is clearly demarcated from the pale yellow sapwood. The wood is hard, very heavy, close-grained, often interlocked, and is both durable and termite-resistant. It has been widely used for fence posts. The wood makes an excellent fuel and a good charcoal. It burns with intense heat whether it is green or dry, and if burnt alone the heat may buckle firebars. The ash content is high, in the range 6 - 8% in charcoal. The tree can provide shade and shelter. The plant has sometimes been used in rehabilitation projects on mine waste sites. The flowers are a useful source of pollen for bees.
Wikipedia
Source ↗Acacia cambagei, commonly known as gidgee, gidyea, gidya, gidgea or stinking wattle is a species of flowering plant in the family Fabaceae and is endemic to north-eastern Australia. It is a spreading, foul-smelling tree with narrowly elliptic to linear phyllodes, spherical heads of golden yellow flowers, and narrowly oblong, papery pods up to 130 mm (5.1 in) long.
