To Francis Darwin   12 September [1878]

This letter is not yet available online.

Summary

Julius von Sachs’s views on stomata seem largely correct, but CD cannot understand how leaves can survive submerged for such long periods.

Has been observing Drosera and concludes that none of the movement of the tentacles is caused by growth.

Suggests observations to show role of pulvinus in leaf movement.
