From L. A. Errera   15 September 1877

Summary

Young Belgian students [L. A. Errera and Gustave Gevaert] ask CD to read their paper, which summarises Cross and self-fertilisation. They criticise CD’s views on the comparative effects of crossing flowers on the same stem and fertilisation of a flower by its own pollen ["Sur la structure et les modes de fécondation des fleurs", Bull. Soc. Bot. Belg. 17 (1878): 38–181, 182–248].

From L. A. Errera   10 October 1877

Summary

CD has made clear that in Cross and self-fertilisation he had not intended to suggest that autogamie (fertilisation of a flower by its own pollen) is superior to gitonogamie (fertilisation of a flower by one on the same plant).
