English: Cockspur Thorn (Maclura cochichinensis) is a native climber or shrub which has curved spines (like the spur on a roosters leg). It is in the family Moraceae (the same as the figs) and has a milky sap. Although native to Australia, it natural range spreads from China to NSW. The Australian Museum says "it is a host plant for the Common Crow Butterfly and provides valuable habitat for many small birds to hide and nest in with a degree of safety from larger predators. Cockspur Thorn is also used by Butcher Birds as a useful spike on which to impale their victims! All in all, they are a prickly character, but crucial habitat in our disturbed landscape." It is suspected of poisoning stock, but this has never been proven.
