Is this a prickly pear?
I originally thought this was a prickly pear, but now the thorns seem too big for it to be one. I was hoping someone could help me identify it.
This is a transplanted section of a larger cactus, which had about five sections with a couple unopened flowers. The largest thorns are 3.5 cm. It was growing in very dry sandy soil. I also saw another of these plants growing in a wetter location, however it was discolored reds and yellows and looked unhealthy.
