Abstract
WHEN a plant population grows in a patchy environment, it can be exposed to a variety of selective pressures. If the resulting disruptive selection is strong enough, intra-population differentiation can occur over distances of a few metres, in spite of the absence of any barriers to gene flow1,2. We wish to report an example of such differentiation within a population of the annual forb Veronica peregrina L.: the differentiation is with respect to physiological responses to varying régimes of soil moisture.
