植物收集雨水有几个原因；然而，在生活在缺水环境中的植物中，最容易看到雨水收集的特征，在那里节约用水供应是最关键的。例如，许多雨水收集器是附生的，生活在寄主树木的树冠上。附生植物不能利用森林地面储存的水，因此缺乏可靠的供水。由于它们悬浮在地面上，它们的根也容易干燥和血栓。这使得附生的生活方式类似于生活在沙漠中。因此，附生植物与沙漠植物在形态上有许多相似之处也就不足为奇了。
Plants harvest rainwater for a several reasons; however, rain-harvesting traits are most readily seen in plants that inhabit water-scarce environments where economizing water supply is most critical. For example, many rain harvesters are epiphytic and live in the canopy of their host trees. Epiphytes cannot utilize water stored in the forest floor and therefore lack a reliable water supply. Because they are suspended off the ground, their roots are also susceptible to desiccation and embolism. This makes the epiphytic lifestyle akin to living in the desert. It is perhaps no wonder then that epiphytic plants share many morphological adaptations with desert plants.
