Footnotes

The date is conjectured on the supposition that the memorandum was handed to Hooker when he visited Down on 13 June 1870 (letter to St G. J. Mivart, 13 June [1870]). See also the letters to J. D. Hooker, 25 May [1870] and [29 June 1870], and the letter from J. D. Hooker, 10 July 1870.
The variety Kermesiana (as CD spells it in Cross and self fertilisation, p. 103), has not been identified. CD raised plants of a red variety of Iberis umbellata from seed bought in England, and crossed them with pollen from plants raised from seed sent from Algiers (Cross and self fertilisation, p. 105).
Nolana prostrata is now N. humifusa. CD had carried out crossing experiments with N. prostrata in 1862 and 1867 (Cross and self fertilisation), but mentions no further experiments.
CD carried out crossing experiments with Hibiscus africanus (now H. trionum; Cross and self fertilisation, pp. 140–1), but did not mention using seed from Algiers.
Canna warszewiczii is now C. indica. CD carried out crossing experiments with C. warszewiczii (Cross and self fertilisation, pp. 230–3), but did not mention using seed from Algiers.
After the list and before the signature, Hooker wrote, ‘A little of each is enough.’

Summary

Orders seeds, ripened in Algiers; imported seed would be of no use. [Forwarded to Algiers by JDH, see 7272.]
