Tiny Tuesday 72 - not much of a mystery!

I'm afraid that I didn't see that we were to post a mystery item this week and even if I had, I'm posting a whole day late!
I think that you will all quickly see that my shot is a close up of one of the many cacti that grow on the island.  Most of the garden areas  at the hotel feature several varieties amongst the flowers and shrubs.
Tuesday was another lounging day but I don't feel guilty:  when we get back there'll be lots of work to greet us, much of which I am not looking forward to one little bit!
