Seed pod.

Been out and about picking up seed pods to blip. This one is long and thin and you can see the little spaces for the seeds, some of which are on the table. 
Not sure of the name - will endeavour to find out when brother in law comes back, but they are rather photogenic.
Beautifully sunny again today - and hot! Gather the same in the UK - so maybe summer arrived finally. 
Just looked it up and it is one of the Flamboyant tree pods - Delonix Regia.
