The date is conjectured on the supposition that the memorandum washanded to Hooker when he visited Down on 13 June 1870 (letter to StG. J. Mivart, 13 June [1870]). See also the letters to J. D. Hooker, 25 May [1870] and [29 June1870], and the letter from J. D. Hooker, 10 July 1870.
The variety Kermesiana (as CD spells it in Cross and selffertilisation, p. 103), has not been identified. CD raised plants of a redvariety of Iberis umbellata from seed bought in England, and crossedthem 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 outcrossing experiments with N. prostrata in 1862 and 1867 (Cross andself fertilisation), but mentions no further experiments.
CD carried out crossing experiments with Hibiscus africanus (nowH. trionum; Cross and self fertilisation, pp. 140–1), but did notmention using seed from Algiers.
Canna warszewiczii is now C. indica. CD carried out crossingexperiments 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 ofeach is enough.’
