Abstract Transpiration from a low, closely matted perennial grass has been measured daily by a floating lysimeter, over a period which included a long natural drought. Transpiration was found to continue at a level determined by the physics of the environment until all the available moisture in the root range was exhausted. This supports Veihmeyer's hypothesis that available water is freely available to the plant between field capacity and wilting point.
