The strangest fruit on Earth? What's it?
The fruit is similar in shape to that of the pitanga or Surinam cherry (Eugenia uniflora) but its fruit is red ripening to dark purple-red, not blue, and it’s a little larger. Eugenia fruits come in other colours but I haven't seen metallic blue. The related Australian species Syzygium unipunctatum (syn. Waterhousea unipunctata) is closer but that wouldn't occur naturally along the Amazon. How many seeds are in the fruit and did you see the plants from which they came?
