Peacocks and Cactus
Most of the plants in this photo are not cactus, but both of the birds are peacocks. Some people who are unfamiliar with desert vegetation in America classify all drought tolerant plants as cactus. But cactus are a very specific type of plant. A cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. Cactus have spines that come from specialized structures called areoles. They are also native to the American continents and any other instances are attributed to migration. There is one species of cactus that grows in Africa and Sri Lanka but scientists theorize that it was somehow imported from America.
