Proportions of different forms of Lythrum.
The Manor | Llandudno
Dear Uncle Charles
Of 256 specimens of Lythrum gathered this morning from different plants, we find
94 with long pistil
95 — middle length pistil
69 — shortest pistil.
These plants were all in one large field or near it but tomorrow we will go if we can manage it in a different direction for more— We find it rather difficult in gathering to know what are distinct plants and what only offsets. At Criccieth & Aber we thought the different sorts usually grew in plots together mixed with a few of the others but here they are all together. We have found the Hottonia, and find the pistils of different lengths as I think you told us.

- f1 3681.f1Dated by CD's annotation, and by reference to CD's reply to this letter (letter to K. E. S., L. C., and M. S. Wedgwood, 4 [August 1862]).
- f2 3681.f2CD wanted to know the proportions of the three forms of Lythrum salicaria in different localities (see, for example, the letter to W. E. Darwin, [2--3 August 1862]), and had evidently asked his nieces, Katherine Elizabeth Sophy, Margaret Susan, and Lucy Caroline Wedgwood, to examine specimens during their visit to North Wales. Margaret provided a further tally of the three forms in the letter from M. S. Wedgwood, [6 August 1862]; CD quoted the totals in `Three forms of Lythrum salicaria', p. 174 (Collected papers 2: 110).
- f3 3681.f3CD had learned from Charles Cardale Babington that Hottonia was dimorphic, and was anxious to see specimens (see letter from C. C. Babington, 17 January 1862, and letter to C. C. Babington, 20 January ). See also letter to K. E. S., L. C., and M. S. Wedgwood, 4 [August 1862], and letter from M. S. Wedgwood, [6 August 1862].
