Darwin, C. R. to Watson, H. C.

8 [Aug 1862]


Asks HCW’s help with his experiments on Lythrum salicaria, for which he needs flowers of the rare Lythrum hyssopifolia.

My dear Mr Watson

You are accustomed to me applying to you when in want. And now I am in great want. I am trying a most laborious series of experiments on Lythrum salicaria, & I think if the result can be proved, which I fully expect to be the case, you will think that your aid will be worth bestowing.f2

what I want intensely is a few fresh flowers of the rare Lythrum hyssopifolia. Vaucher says it presents two forms like Primula,f3 & these would be invaluable to me; why they would be so is too long a story for a note. Can you give me address (& allow me to use your name) to some one or two Botanists, who may live anywhere near this plant, & who would aid me.—f4 If too late for fresh plants, perhaps I could then get seed.— If you can, will you aid me?—

I have had a sick House for last 8 weeks, with one of my poor Boys terribly ill, whom we must take to sea-side next week.f5 All this has cut up my work in a cruel degree.— How is your poor patient, whom you mentioned a year or so ago:f6 you spoke then as if there was little hope. For five years we have never been a whole month without some anxiety. It is a weary world.—

Yours very sincerely | Ch. Darwin

The date given by CD has been changed on the basis of Watson’s endorsement and CD’s reference to Leonard Darwin’s having been ill for ‘8 weeks’ (see nn. 5 and 7, below).
For CD’s experiments on Lythrum salicaria, see, for example, the letter to Daniel Oliver, 29 [July 1862] and n. 6.
Vaucher 1841, 2: 371.
No letter from Watson on this subject has been found; however, in ‘Three forms of Lythrum salicaria’, p. 190, CD thanked Watson for having provided him with dried specimens of L. hyssopifolia (Collected papers 2: 124).
CD refers to Leonard Darwin, who had been ill with scarlet fever since mid-June (see letter to W. E. Darwin, 13 [June 1862]).
This individual has not been identified.
Watson wrote ‘Augt’ over ‘July’; he also wrote ‘Augt.’ above CD’s date.
