Abstract
A SATISFACTORY physical theory of salt absorption by plants has been long awaited. The general reader might infer from the communication by Lundegardh1 that such is now available, but this conclusion should not be drawn without a full consideration of all the evidence. It is our view that Lundegardh's explanation of the mechanism of salt absorption represents an over-simplification of a very complicated problem the ramifications of which are only just becoming evident. That this is so is shown by extensive investigations to which we shall refer.
