Summary

Describes his experiments on Nepenthes; finds action analogous to that in Drosera.

Date:  25 Oct 1873
Classmark:  DAR 103: 175

Summary

Extremely glad to hear of the aggregation in Nepenthes glands. Advises on experimenting with cubes of albumen – gives sizes, also suggests cubes of roast meat. Thanks for analyses of secretion of Nepenthes.

Asks for cutting of Acacia farnesiana.

Longs to examine a species of Desmodium with three leaflets. Has asked Frank [Darwin] to look for species of Desmodium with tendrils.

Summary

Sends plant specimens.

He and Thiselton-Dyer, working on with Nepenthes, have independently found the spiral vessels going to the gland. CD’s view that the glands are secretory organs is suggestive. When Nepenthes is as much done as CD wants,

he will turn to Cephalotus and Sarracenia.

Summary

Thanks for leaves. His notes on them will be of greatest service.

He cannot distinguish some Eucalypti from Acacia. Sends specimens, with numbers, for JDH to name.

Acacia farnesiana branches arrived withered, but saw enough to make him wish to examine the plant.

Has thought of some troublesome experiments for Drosophyllum.

Encloses remarks [missing] by Searles Wood, with which CD disagrees, about a new and strongly marked variety transmitting its characters.

The competition of better adapted forms seems to CD a sufficient explanation [for extinction].

Summary

On Nepenthes.

Asks JDH, if he publishes, to mention CD’s work on digestive powers of Drosera so that charges of plagiarism will not be made against CD later when he publishes.

Describes at length his observations on the movements of Desmodium.

Summary

Sends leaves and names by post.

Is writing everywhere for Drosophyllum.

Is deeply interested in Desmodium.

Had no intention of publishing on Nepenthes, the experiments were solely for CD’s "eating". Will continue with egg and raw meat experiments. Asks for advice on how to prove fluid is secreted by the glands.

Searles Wood’s letter is confused and would deny atavism if his principles were accepted.

To J. D. Hooker   3 November [1873]

Summary

Discusses experiments and observations on pitchers [of Nepenthes]. Suggests procedures for JDH to follow.

Any plant of any family with a terminal or with any lateral leaflets greatly reduced would be interesting to CD for studying spontaneous movements.

Has not received Eucalyptus or Acacia plants from Rollisson.

Summary

Returned from visit.

Thinks several species of Eucalyptus would be worth experimenting on. Sends list.Mimosa albida would be worth its weight in diamonds. Neptunia worth more than diamonds.

Summary

Has had a week’s cessation of Nepenthes work.

Had to get out a paper for the Linnean Society on Thursday.

Has tried Mimosa albida in hothouse and found it wonderfully sensitive.

A military report from India praises his travel book.

Summary

Has been working hard on Mimosa albida. Could JDH ever make its opposite leaflets shut up close, as in sleep, when he irritated them? CD doubts they do, except in sleep. Thinks movement a protection against water.

Has examined only one specimen of Eucalyptus.

Cannot believe JDH’s results from cutting a hole in pitcher in his Nepenthes experiment.

Summary

He has noticed that Mimosa albida leaves closed only partially. It can be objected to CD’s theory that, if true, all, or at least more, species would close their leaves on application of water, unless he can show special injury done to M. albida by water.

Summary

His indignation at the malignant, odious, hypocrite Owen’s attack on JDH. History of Secretaryship [of Royal Society in Nature 9 (1873): 129–30] was best answer to Owen.

Is hard at work on new edition of Descent – a truly awful job.

No use going on with experiments on effects of water on bloom-divested leaves. May have erred. Or it may be that water is only injurious when there is a good supply of actinic rays. Will wait until spring.
