Members of the plant family Cactaceae (cacti) are native to the Americas and thrive in dry environments. They have a number of specialized adaptations, including reduced leaves, succulent (fleshy) stems for water storage, and spines for defense against herbivores. Some members of the family Euphorbiaceae are native to the African desert and resemble cacti, having similarly reduced leaves, succulent stems, and thorns. Other species in the Euphorbeaceae do not have these traits.
