Yes is a cactus I have a pic where you will see the complete plant. It was a sunny day that gave it that color.
That's close but I don't think so. The color of this is more light purple than O. basilaris and the sharp pointed shape of the petals don't quite match. MinervaMar, do you have any more photos of this to help with ID?
Yes must be cactus... Dan is it Opuntia basilaris..?
Though I can't see any of the plant, I believe this is the flower from a cactus. Perhaps Hylocereus or some type of nightblooming cactus. http://en.wikipedia.org/wiki/Hylocereus
