But if this is at all an argument, it is one from which the sexualist has but little to fear; as in the case of slips and layers there is in fact no production of a new individual, but merely a prolongation of the old; or at best a multiplication by means of division, as in the case of the Polypi: and although plants are capable of being multiplied in this manner, it is no proof that they may not be propagated by means of sexual intercourse also.

Both the asexualist Spallanzini and the sexualist Erasmus Darwin cited Koelreuter, and the German botanist Johann Hedwig, the first to describe male and female reproductive structures in nonseed plants (cryptogams), declared in 1798 that Koelreuter had demonstrated “beyond all doubt" that "propagation by sexual union takes place in the plant world also."

It was the sexualists who successfully freed their minds from such cultural biases and glimpsed the true sexual nature of plants. The sexualists went on to demonstrate the presence of both the sexual and asexual generations in the life cycles of all plants, as revealed by Hofmeister's great synthesis, thus enabling the asexualists to share in the ultimate solution to the puzzle.
