Abstract Pure samples of the antheridiogen of Anemia phyllitidis (A An ) were tested for their ability to affect the growth of dwarf corn (d 5 ) and lettuce seedlings, and to influence α‐amylase production by barley half‐seeds. Stimulation of dwarf corn growth and barley amylase production was, on a molar basis, from 1/2 to 1/250 that given by GA 3. In lettuce, A An had a synergistic effect with low levels of GA 3 ; alone, A An was inhibitory or ineffective. Therefore, in addition to having a close chemical resemblance to gibberellin, A An induces similar, but not identical physiological responses in flowering plants as well as ferns.
