Pick a Picture - Nut or Not?

Six of these nuts are true nuts in the botanical sense, and the others... are not.
Can you guess which is which?

A botanical nut is a hard-shelled pod that contains both the fruit and seed of the plant, where the fruit does not open to release the seed to the world

Whoops, just realised there was an error on the quiz. So at least one nut that you probably thought was a nut is in fact a nut, and not not a nut. Apologies for any confusion, hope that clarifies things.

Still, it was hard to find nuts that are nuts for the quiz. I'd always assumed that at least half of common culinary nuts were botanical nuts. I mean, why does that fact about peanuts not being nuts get so much press when most other culinary nuts aren't nuts either?
