To Alphonse de Candolle   11 October 1869


Thanks AdeC for his interesting letter [6915]. The experiment strikes CD as a very valuable one. CD has forwarded the letter to Hooker, who is glad to make the trial. CD will have many experiments in progress next spring but he will open the packet of seeds and if they are numerous, will try a few himself.

From Alphonse de Candolle   28 September 1869


Reports on the differences of growth and development of plants of three species grown at Geneva from seed collected at different localities. Forwards seed for CD to plant and observe differences in development.

Carl Linsseer has published a memoir on the times of flowering, foliation, etc. of diverse species in different parts of Europe [Mem. Acad. Imp. Sci. St.-Pétersbourg 7th ser. 11 no. 7 (1868)] and concludes that the northern forms are more forward and that this is hereditary. AdeC’s experiments carried out on annuals, show only the effects of heredity; probably the direct action of physical conditions affects development, at least in perennial species.
