Basil of Caesarea

How then, they say, can Scripture describe all the plants of the earth as seed-bearing, when the reed, couch-grass, mint, crocus, garlic, and the flowering rush and countless other species, produce no seed? To this we reply that many vegetables have their seminal virtue in the lower part and in the roots. The reed, for example, after its annual growth sends forth a protuberance from its roots, which takes the place of seed for future trees. Numbers of other vegetables are the same and all over the earth reproduce by the roots. Nothing then is truer than that each plant produces its seed or contains some seminal virtue; this is what is meant by "after its kind." So that the shoot of a reed does not produce an olive tree, but from a reed grows another reed, and from one sort of seed a plant of the same sort always germinates. Thus, all which sprang from the earth, in its first bringing forth, is kept the same to our time, thanks to the constant reproduction of kind.
