It looks like Tree Spinach to me yet you'll need other opinions. Are the flowers on those bracts small and white?
Spinach Tree, Tread Softly, Cabbage Star, Chaya
Cnidoscolus aconitifolius
Delicious, full of nutrients, and also full of Cyanide and possibly fatal if not boiled at least 15 minutes to relieve the gas'! (If it is) A beautiful plant and great pic's even if I'm not right!
