The Sonoran Desert's location is at latitude 25° to 33° N. Hot deserts contain sparse populations of plants, due to periods of high temperatures and low water availability. This high temperature results in high rates of evapotranspiration levels, which in turn results to very little water available for this biome. The temperature is a lot higher than the average annual precipitation. This has a large influence on plant forms. Because it is so dry, stem succulents occur in the cacti of these desert plants. Plants with succulent stems can store water in their stems so they are not left dry during dry seasons. Cactuses are the main desert plants. Cactuses can absorb a large amount of water, which is beneficial as this desert has a higher annual precipitation than most hot deserts. Most the flowers located in this desert also depend on rainfall so they can flower, and for a hot desert, this has a high amount of annual precipitations, so vegetation numbers must be high
