Glad to hear of the plant; CD instructs WED to make further observations. If it is a good case he will insist on WED's sending a communication to the Linnean Society.
My dear W.
(Papa is dictating)
I am very glad to hear of the plant, but you are worse than a villain thus to tantalize
me. I hope it is not the Buck bean for that
You might begin thus ``as the existence of two forms in the same species of plant has lately been shewn to be of functional importance I beg permission to lay the following case before the Linn. Soc''
But after all perhaps the case will break down as so many have with me.
Now It's me—
I do hope poor little Evelyn will not be very ill.

Edmund has invited the Josselinas to the boat races at Cambridge which pleases them very much. Uncle C. L. takes them & Aunt Eliz. Chaperones them. Our visit here has not done Horace any good tho' he has a good deal of enjoyment but his stomach is worse than usual.

- f1 4139f.f1Dated by the references to the Darwin family's visits to Hartfield Grove and Leith Hill Place (see nn. 2 and 8, below); the Monday before the Darwin family left Hartfield Grove was 4 May 1863.
- f2 4139f.f2According to Emma Darwin's diary (DAR 242), the Darwin family stayed at Hartfield Grove in Hartfield, Sussex, the home of Charles Langton, between 27 April and 6 May 1863.
- f3 4139f.f3The letter from William has not been found. William's observations related to a possibly dimorphic plant, later identified as Pulmonaria angustifolia (see following letter and n. 1). CD was interested in finding further examples of dimorphic species after discovering that dimorphic flowers in Primula and Linum were an adaptation for reciprocal pollination (see `Dimorphic condition in Primula' and `Two forms in species of Linum').
- f4 4139f.f4CD refers to the mainly aquatic perennial Menyanthes trifoliata, in which the occurrence of dimorphism was an established fact (see Correspondence vol. 10, letter to C. C. Babington, 20 January  and n. 3). CD was anxious to examine this species and had made attempts to obtain specimens in 1862 (see ibid.).
- f5 4139f.f5William's observations on dimorphism in Pulmonaria angustifolia were not communicated to the Linnean Society; however, CD gave a detailed account of them in Forms of flowers, pp. 105--7.
- f6 4139f.f6The reference is to Evelyn George Hammond Atherley, son of William's banking partner George Atherley (`Genealogical notes', Records research room, Southampton City Archives).
- f7 4139f.f7Mrs Ashworth has not been further identified.
- f8 4139f.f8Leith Hill Place, near Dorking, Surrey, was the home of Josiah Wedgwood III and his wife Caroline, CD's sister. According to Emma Darwin's diary (DAR 242), the Darwins stayed at Leith Hill Place from Wednesday 6 May 1863 until 13 May, when they returned to Down House. On Tuesday 5 May 1863, Emma recorded in her diary that CD had been `poorly & languid all week'. CD had been in London for ten days in February (see `Journal' (Correspondence vol. 11, Appendix II)).
- f9 4139f.f9Henrietta Emma and Horace Darwin.
- f10 4139f.f10Emma apparently refers to the photograph of CD taken by William in April 1861 (see Correspondence vol. 9, frontispiece). In 1861, William was studying at Christ's College, Cambridge (Alum. Cantab.), and may have deposited the negative plate with a firm of photographers there. CD wanted a copy of the photograph to send to Roland Trimen (see letter to Roland Trimen, 23 May ).
- f11 4139f.f11On Sunday 3 May 1863, Emma Darwin recorded in her diary (DAR 242) that it had been a `beautiful day' and that they had `walked to Brook on common'. Buck bean (see n. 4, above) flowers between April and June.
- f12 4139f.f12The `Josselinas' was a family nickname for the daughters of Caroline and Josiah Wedgwood III (see Correspondence vol. 6, letter to W. E. Darwin, [17 February 1857] and n. 10). Sophy Wedgwood was 21 years old, Margaret 19, and Lucy 16. Emma also refers to Charles Langton, Sarah Elizabeth Wedgwood, and Charles Langton's son, Edmund Langton, who was an undergraduate at Trinity College, Cambridge (Freeman 1978, Darwin pedigree, Admissions to Trinity College, Cambridge).
- f13 4139f.f13In 1863, George Howard Darwin competed unsuccessfully for an entrance scholarship at St John's College, Cambridge (DNB). See also letter to Edward Cresy, 13 May .
- f14 4139f.f14Alfred Wrigley was headmaster of Clapham Grammar School (Alum. Cantab.), where George had been a student since 1856 (DNB). It was subsequently decided that George should return to school for another year (see letter to Edward Cresy, 13 May ).
