To H. C. Watson   8 [August 1862]1

July 8th

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.2

what I want intensely is a few fresh flowers of the rare Lythrum hyssopifolia. Vaucher says it presents two forms like Primula,3 & 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.—4 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.5 All this has cut up my work in a cruel degree.— How is your poor patient, whom you mentioned a year or so ago:6 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.
