It was lately asserted, upon what seemed very strong evidence, that the Aegilops ovata, a plant growing wild in Southern France, had been actually converted into common wheat; but, upon a repetition of the experiments, later observers have declared that the apparent change was only a case of temporary hybridation or fecundation by the pollen of true wheat, and that the grass alleged to be transformed into wheat could not be perpetuated as such from its own seed.
Another common oak is Quercus AEgilops, a much smaller and deciduous tree, very stout-trunked, which grows in scattered groups on Carmel and elsewhere, "giving a park-like appearance to the landscape."
The hybrid between Aegilops ovata, a small weed, and the common wheat is of itself sterile, producing no good pollen. But it may be fertilized by the pollen of wheat and then gives rise to a secondary hybrid, which is no other than the Aegilops speltaeformis. This remained constant in Godron's experiments during a number of generations, and has been constant up to the present time.
It is one of the oldest hybrids with a pure and known lineage. The original cross has been repeated by Urban, who found the hybrid race to be constant from the beginning. Another very notorious constant hybrid race is the Aegilops speltaeformis. It has been cultivated in botanic gardens for more than half a century, mostly in annual or biennial generations.
