SUMMARYA report of an alkoxypurine showing cytokinin activity is presented. This compound, 6‐benzyloxypurine, has been tested in three tests and in two of these, a wheat leaf senescence and a young coleoptile test, the compound is as active as benzyladenine or kinetin. Although it is much less effective on molar basis than these compounds in a tobacco tissue culture test, it is as active at its optimum concentration. In addition to promoting cell division the presence of 6‐benzyloxypurine leads to morphological differentiation within the tobacco stem tissue, and whole plants have been grown without altering the nutrient med
