Cordate/Reniform leaf succulent
This cutting was taken from a coastal path in Charco del Palo, in Mala, on Lanzarote, Las Palmas (Canary Islands) (17 Jul 11).
It has heart-shaped leaves and the largest leaf width is 10mm. It looks similar to a Crassula argentea that I have in London, but I have searched and searched online to no avail for this particular plant.
I hope someone will be able to help me identify this! Thanks in advance!

I didn't recognize this plant at first, because mostly what you see in flower shops and other places that sell plants is the variegated form; this is Portulacaria afra, the Elephants Food.
It's native to South Africa, so it's a bit out of it's natural habitat, I'm imagining someone had one and it reseeded itself.
As far as I know, it's not an invasive species, although it does seem to be very adaptable in any frost free areas.
