The tree cactus is remarkably well adapted to very dry conditions. The root system is broad and near the surface where water from light rains can be absorbed rapidly. The bulk of the plant is made up of soft, water-storing tissues, which are light green near the surface and yellowish within; juicy and slightly salty in taste. This retains water that has been absorbed after rains for use over long dry periods. The surface area is greatly reduced through absence of leaves, and loss of water to the air (transpiration) is correspondingly checked. The branches have a very thick skin which also retards evaporation and, being green, at the same time carry on the processes of food manufacture (photosynthesis), normally functions of the green leaves. Further, the formidable spines protect the juicy stems from animal life[
