wrong kind of data, and this will certainly happen if physiological
investigations come to be based upon too narrow an acquaintance with
the many and complex factors involved in the evolution of plant
populations.
ACKNOWLEDGMENTS
To my colleagues, Professor K. Mather and Dr D. A . Wains, I am
indebted for much stimulating discussion of the topic of this article;
they may have influenced what I have written, but they are in no way
responsible for its deficiencies. My warm thanks are due to Miss Gillian
Nolan for assistance with the bibliography.
