Bellyache bush is a tropical shrub or small tree. It forms dense thickets that crowd out other vegetation. It is a Weed of National Significance.
Bellyache bush invades disturbed areas and overgrazed pastures, forming dense thickets that crowd out other vegetation. Its seeds are highly toxic to stock and humans, and its sap can cause dermatitis. It has been declared a Weed of National Significance in Australia.
What to do if a person is poisoned:
Bellyache bush is an erect shrub or small tree up to 4 m high. Leaves are green to purple, 5 to 14 cm long and 7 to 13 cm wide with 3 to 5 lobes. The leaves are sticky and the bush contains watery sap. Flowers are 6 to 9 mm wide with red to purple petals that have yellow bases. Flowering occurs most of the year but predominantly in late summer and autumn. Fruit are oblong, three-lobed capsules about 1.1 cm long, containing 2 or 3 brown seeds 0.6 to 0.8 cm long. Capsules are initially green and ripen to dark brown.
Bellyache bush is native from Mexico to Paraguay, and was probably introduced to Australia as an ornamental plant in the late 1800s. Bellyache bush is a tropical species that is frost sensitive, it is unlikely to survive in New South Wales.

It describes the state and regional priorities for weeds in New South Wales, Australia.
|All of NSW||General Biosecurity Duty
All plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable.
|All of NSW||
Prohibition on certain dealings
Must not be imported into the state, sold, bartered, exchanged or offered for sale.
Regional Recommended Measure* (for Regional Priority - Prevention)
Land managers should mitigate the risk of new weeds being introduced to their land. The plant should be eradicated from the land and the land kept free of the plant. The plant should not be bought, sold, grown, carried or released into the environment. Notify local control authority if found.
