Zygocactus, commonly called Brazilian Beauty or Crab Cactus, is a tree-perching, spineless cactus. The only species z. truncatus, is a true epiphytic plant native to Brazil.
It is sometimes botanically classified as Phyllocactus or Schlumbergeria, but differs from them in having soft 'teeth' along its leaves and is distinquished from closely related Epiphyllums by the irregular shape of its spectacularly handsome blooms.
