AKA Marble berries, which grow in central west Africa.
Has anyone ever seen them or photographed them?
Right up Mr Krebs' street, I think.
A plant sold in 2015 on Italian ebay for $35 - may not have been in fruit though!
It would make a change from butterflies and beetles.

I had heard of them, and pictures are available online:

I remember learning that they are an example of a structural color, which are the metallic colors more often seen in animals (think blue morpho butterflies, or metallic green beetles). The effect is caused by differential interference of light.

That's right Mark. I found them while searching for things about organic structural colours. Most are animals.
The pointilist nature of the structure is interesting.
I'm not far from Kew Gardens, "largest and most diverse botanical and mycological collections in the world" so I'll ask if they can show me any.
Perhaps I can scrounge a berry.

I don't see a "full tect" link, only the abstract.
Read the "Reply" though.
