CAMERARIUS, Rudolph Jacob (Camerer)
Tübingen: Vidua Rommeii, 1694.
First experimental demonstration of the sexuality of plants. Camerer showed that in flowering plants the anthers are male organs, and that the ovary with style and stigma are female, and that pollen is required for the production of viable seeds. Until his work, the continuity of reproductive processes in plants and animals had been a matter of speculation; after it, the scientific study of fertilization and hybridization became possible. Second edition in Valentini's Polychresta exotica (1700). Digital facsimile of the 1700 edition from the Biodiversity Heritage Library at this link.
