More weeds: Wild Poinsettia

This little weed is related to red leaved Poinsettias that people here like to give as Christmas gifts because it flowers at that time.

Wild Poinsettia or Euphorbia geniculata is native to North America but has found it way here. If you look at the picture above, you'll see that there are tiny little anthers and stamens but like many other Euphorbia species, there are no petals, just an enlarged ovary.
