Funky Seed Pods

Whilst shopping in a garden centre over the Christmas period, I came across these funny looking seed pods (which are now pride of place in my mosaic bowl on the window sill). They have big crater-like things on the surface, which I assume held seeds at one point, and look like a frilled mushroom on the back.

Cool aren't they?
They remind me a bit of a plant I saw in Kew Gardens over the summer- maybe it's the same kind, I have no idea!
