Summary

Many CP-books describe the trapping mechanism of Drosera generally as leaves with sticky stalked glands, which are able to bend towards the caught prey. However, the traps are actually not that simple. Even as early as 1875, Charles Darwin, in his book ldquo;The Insectivorous Plants” (Darwin 1888) and a few later scientific publications mention two different tentacle structures for Drosera rotundifolia.
