From Gaston de Saporta 2 September 1876
Summary
Claims to have proved the great antiquity of several plant races. But this does not contradict the tendency to vary. Insists that heredity can make permanent varieties of sufficient duration to occur as fossils.

To Gaston de Saporta 10 September 1876
Summary
Hopes GdeS will publish on subjects discussed in his letter [10587]. CD had noted similar persistence of variation in fossil shells.
Calls his attention to Nägeli’s work on Hieracium.
Expresses skepticism about O. Heer’s view that dicotyledonous plants developed suddenly. Believes they must have developed slowly in some part of the globe completely isolated from other regions.

To Gaston de Saporta 11 October 1877
Summary
Thanks GdeS for communicating his discovery. It is especially important at a time when several naturalists have declared that development occurs quite suddenly at intervals. Joseph Le Conte in N. America urges that even new families and orders are developed within an extremely short period.

From Gaston de Saporta 16 December 1877
Summary
He has heard CD is about to be elected to the Académie des Sciences.
Cross and self-fertilisation, with its emphasis on insect pollination, helps explain the problem he has worked on for so long: i.e., the rapid diversification of angiosperms in the fossil record occurs in conjunction with the diversification of insects.

To Gaston de Saporta 24 December 1877
Summary
Such honours as proposal for election to Institut affect CD very little.
GdeS’s idea that dicotyledonous plants were not developed until sucking insects evolved is a splendid one. The suggestion that fertilisation of the surviving members of the most ancient dicotyledons should be studied is a good one. CD hopes GdeS will keep it in mind.

To Gaston de Saporta 15 August 1878
Summary
It would be false to pretend he cares very much about his election to the Institut.
Glad to hear GdeS plans to publish a work on the more ancient fossil plants. Hopes he will report also on the more recent Tertiary forms because the close gradation of such forms is "a fact of paramount importance for the principle of evolution".

Thanks for GdeS’s Le monde des plantes [1879].
CD has just read "Végétation polaire" [C. R. Congr. Int. Sci. Geogr. 1 (1878): 197–242] with interest. Hooker gave it conspicuous place in his Royal Society Address (1878).

Summary
Thanks for work sent by GdeS and A. F. Marion [L’évolution du règne végétal 1 (1881)]. CD greatly pleased at boldness with which GdeS expresses his belief in evolution. Some of GdeS’s countrymen have been "a little timid" on this head.
