'''Spines''' are leaves that have been modified into cylindrical, hard structures with sharp ends. They are occasionally called [[thorn (botany)|thorns]], which is incorrect (thorns are modified branches or stems). Similar to [[Plant spines, prickles and thorns|prickles and thorns]] they are used by plants to protect themselves from herbivores.
