Subthreshold and action potentials in Lupinus stem in response to sub-threshold and threshold stimuli (square constant current pulses) were studied. The occurrence of electrotonic potentials and local responses is demonstrated. The general characteristic of these responses and their amplitudes are the same as demonstrated for the isolated crab axons by Hodgkin (1939) and Hodgkin and Rushton (1946). The course of the phenomenon, however, is about 108-104 times slower in plants
