here is another one ID please
Even photo is blurred, if what can be seen on the left is a star-shaped flower I would say your plant is either a Caralluma, or a Huernia.
Search the net for photos of such plants.
i can see spines, which would mean this is not an asclepiad at all (neither huernia nor caralluma). if you have some clearer photos, that would help.
here is new pictures go to cacti & succulents discussion and look under new pictures to be ID see if you can ID both thanks ro lmk email@example.com
