18 Sept/69

My dear Mr Darwin

Many thanks for your notes and for the kind notice you have taken of the tiny facts I sent you.

I have found out myself this year how comparatively difficult it is to observe physiological functions when owing to bad weather or otherwise the plants are not in full vigour. The pollinia of Orchids did not function half so well in the last cold June as in the hot one of 1868.

I am much interested in what you say about bees getting nectar from below the surface. In the papilionaceous flowers—Ulex, Lupin, &c I see them at work where I can find no nectar— But I find no open staminal tube without nectar. And now I am going to trespass terribly on your good nature & your time.

I have put together a few notes upon a few Papilionaceous flowers and am venturing to send them to you. If you have not time to look at them please send them back: and if you find my scribbling hard to read, I will gladly have it copied. Should you be able to look at the paper I shall be very much obliged if you will tell me whether you think all or any part of it worth printing: and whether it would be wise to keep it for another summer. I am pretty sure of the facts I have stated, but alas! I was in London entirely till July and afterwards too busy, when away from London, with settling here & with Office matters, to do what I should have liked.

The fact is, one needs to go on to the hill side & look & look, & come home and think it over and go & look again before one can be certain of any thing.

It is too late now this year for real flowers and drawings in books are of little use.

Will you kindly return me the paper addressed to me at the Board of Trade and marked ``Private'', where it will need no postage stamps.

And pray do not trouble yourself with it to the detriment of more important work or to your own fatigue.

Hooker is coming to us on the 5th October—and I shall victimize him with Papilionaceous flowers— What a work of labour is his Genera Plantarum. It is Cyclopean like Johnsons Dictionary

If railways will suit, I might come over for an hour or two some day, and thus save you the trouble of writing. Is there any station on the S.E.R.—eg. Godstone Road, Caterham, &c that is within fly-distance of Down?

Believe me | Sincerely yours | T H Farrer

Charles Darwin Esqr FRS

    Farrer's observations of the movement of the pollinia in Ophrys muscifera (now Ophrys insectifera, the fly orchid) and Peristylus viridis (now Coeloglossum viride, the frog orchid) are cited in `Fertilization of orchids', pp. 144, 146 (Collected papers 2: 141, 143). See Correspondence vol. 16, letters from T. H. Farrer, 17 May 1868 and 4 June 1868.

    In `Fertilization of orchids', pp. 142--3 (Collected papers 2: 140), CD added further observations confirming his speculation in Orchids, pp. 50--1, that in many orchid species, insects punctured the inner lining of the nectary, withdrawing nectar that had been secreted between the inner and outer membranes of the nectary.
