Turning his attention to the monoecious plants Ricinus communis and Zea maysCamerarius cut off the male inflorescences below the opening of the anthers; in these cases, too, only empty fruit was produced.

From these experiments Camerarius concluded that the anthers represent the male organs of the plant and the ovary, with style and stigma, the female organs. He considered those plants in which male and female organs coexist in the same flower to be hermaphroditic, and compared them with the snails, the hermaphroditism of which had been discovered shortly before by Swammerdam.

Camerarius further displayed his critical powers as a researcher by raising several objections to his view. Camerarius also saw a serious challenge to his views in the fact that during his experiments, an ear of corn on a castrated plant had produced several fertile kernels, even though the intact plants were far away. In addition, he had encountered a similar phenomenon in experiments on Cannabis.

Valentini wrote to Camerarius. There, Johann Gottlieb Gleditsch induced a female palm tree Chamaerops humilis to produce seeds by dusting it with pollen obtained from a male specimen in the Leipzig Botanical Garden. Gleditsch repeated this experiment in and with equal success. Camerarius had shown that ripe seeds form only if the stigma has been covered with pollen.

Nevertheless, many botanists continued to deny the sexuality of plants until the beginning of the nineteenth century. Finally, the works of Karl Friedrich von Gaertner, who carried out over nine thousand hybridization experiments, overcame the last doubts on the matter. In addition to the Epistola. In the most notable of these. This notion, which Linnaeus, referring to Camerarius, later discussed in his Philosophia hotanicahas been thoroughly confirmed by modern chemotaxonomical methods.
