When I first posted up Cakile edentula just under a year ago @pjd1 said This is rather unusual though as the most common one in New Zealand by far is C. maritima which is all I have seen up on Te Aupouri before and proceeded to educate me about the horns. Since then I have always checked that out but never seen any until today.

This is the only plant that has the horns and is growing by c.edentula which is plentiful at the moment.

Not too sure if is is Cakile maritima or Cakile maritima ssp. maritima
