Hello, here is yet another cactus native to Mexico. I have already had someone tell me, that most likely it is a Echinocactus horizonthalonius, but it looks different than the type that is growing here locally, because of the red and white spines and the less blue-green color. Maybe you have an idea...

Could you help me identify this unusual cactus? The pad of most likely an Opuntia sp. is pale green and was 4 to 5 inches long. The stem piece seems to have no spines, but approximately 1 inch long pony-tail like whitish bundles of what looks like glochids. This plant part was imported from Mexico. ...
