In botany, the term for the evaporation of water via the leaves of plants, especially via their adjustable stomata (stomata, hence "stomatal transpiration"), but also via their remaining outer skin (cuticle, hence "cuticular transpiration"). The amount of water transpired over a period of time is the transpiration rate. The evaporation of water on unvegetated or open land or water surfaces, on the other hand, is called evaporation. The sum of evaporation and transpiration is called evapotranspiration. See also humidity.
