Leaf-like stems (called cladophylls or cladodes) grouped at nodes of major stems, 2-15 (occasionally more) per node, filiform (thread-like), 1-3 cm long. True leaves not green, scale-like, subtending cladophylls and flower pedicels at nodes, some having their spurs extended into spines. Pedicels jointed either near middle or closer to flower bud.
