Cholla (pronounced cho-ya) cactus, also known as the Jumping cholla and the hanging chain cholla. The "jumping cholla" name comes from the ease with which the stems detach when brushed, giving the impression that the stem jumped onto you. Often the merest touch will leave a person with bits of cactus hanging on their clothes to be discovered later, when either sitting or leaning on them. The ground around a mature plant will often be covered with dead stems and young plants started from stems that have fallen from the adult. They attach themselves to desert animals and are dispersed for short distances.
