Plants observed at Lot 1 Amy Johnson Hwy, Rainbow. This 90ha property of Yellow Gum woodland, Mallee woodland, and Dune Heathland, sits between the Birdcage Flora & Fauna Reserve and the Weddings Reserve only a few kilometres north of Lake Hindmarsh.
Nasty weed across inland areas of Australia, infamous for its ferocious spiny fruits that have the ability to puncture tyres and pierce through thin footwear. In Victoria, seems to prefer sandy soils. Only this single plant found at this site (promptly removed and disposed of). Likely arrived on vehicle tyres.
