My dear Madam
I am very much obliged for your extremely interesting letter, & I am glad to hear that you are studying Dionæa in so earnest a manner1 My observations on cultivated plants are now complete, and I shall publish them in six or nine months; though they will be of little value compared with those made on the plant in its own country. As you kindly offer me information, I should very much like to hear about one point. Dr Canby says that the same leaf will catch 2 or 3 insects successively. Now I find with cultivated plants that a leaf which has once caught a good sized insect, though it will open & remain so for a considerable time, has so little power of movement that it most rarely is able to catch a second insect or to close over any object. I should very much like to be able to say, what the truth is on this head.2
I remain dear Madam with my best thanks | Yours very faithfully | Charles Darwin
Will soon publish on insectivorous plants; asks for a particular observation on Dionaea.
