- An upright annual with branches in opposite pairs off the main
stem. The stems are reddish and the leaves are green and have
serrated edges.
- The leaves are made up of three to five leaflets, arranged in
1 or two pairs with a slightly larger terminal leaflet.
- The flowers are inconspicuous and yellowy-orange and occur from
November to May. The seeds are black and 6 to 10 millimetres long
and have barbed edges and two barbed teeth off one end which means
they get easily hooked in animal hair, wool or people's clothing.
This helps the plants to spread.
Control:
Pull out and destroy plants to prevent seeding
and spread or apply herbicide such as glyphosate (eg. Roundup)
