The ocotillo is a desert plant with long, straight branches. Its leaves are small and appear for only a short time after a rain. Most of the time, the branches of the ocotillo do not have leaves. Maple trees grow in areas where water is more abundant than in the desert. Maple leaves can be very large and are present for most months of the year. Ocotillo plants are better adapted for surviving in the desert than maple trees because the characteristics of ocotillo leaves —
prevent the plant from producing flowers
encourage the release of carbon dioxide from the stems
reduce the amount of water lost through evaporation
allow more sunlight to reach the soil
