"...I think that I have succeeded in showing. . . kind of movement common to all parts of all plants from their earliest youth."

- Charles Darwin, The Life and Letters of Charles Darwin, Volume II (1880)

The Power of Movement in Plants (1880) includes illustrations and documents the extensive research and study of phototropism among other plant movements by Charles Darwin and his son, Francis. The chapters focus particularly on a plant's evolution and adaptation to external stimuli with particular attention to circumnutation. This in-depth research is a must-read for lovers of the origins of botany and biology.
