A correspondent sends us the following as remarkable. It is from a communication by Dr. E. Bonavia, of Etawah, East Indies, to the London Gardeners' Chronicle, page 736 of last year:

"In the same year I obtained a few seeds of the Cuzco Maize of the Andes - a large white variety. I managed to obtain a cross between this and the native Maize - a very small grained yellow variety. The result of the first crossed seed was encouraging. It produced a Maize of large size, of a light yellow color. Further experiments with it produced curious varieties. Some plants threw out branches where the ears or cobs should have formed; others, among the head of male flowers, on the summit of the stem, produced grains resembling those of Sorghum, but larger. This phenomenon led me to believe that the relationship between the Maize (which is monoecious) and the Sorghum, is more intimate than one would have at first supposed. I had proposed to myself, to make some further interesting, and probably useful, experiments with this hybrid; but a few months' absence from Lucknow put an end to them. On my return I could not find the seeds, and the native gardener could not account for their having been lost. Latterly I perceive that Mr. Duthie. of the Saharunpore Botanic Garden, has effected a similar cross.

I hope he may be more successful than I was, and that he may be perhaps able to prove, that the Zea and the Sorghum are not, after all, distinct genera ! With regard to the original Cuzco Maize, nothing could be made of it. It was evidently not suited to the plains of India, its habitat being in the Andes".

We have to remember, that in the old world, there does not appear to be the same knowledge of the extent to which plants will naturally vary, independently of hybridization, as exists in the United States. Hybridization is, in these old-world experiences, continually brought in to account for phenomena which here we should refer to mere "sporting," which is the every-day word for natural variation. In our country, we continually find Indian corn with small Sorghum-like grains among the male flowers in the tassel; and male flowers from the ends of the cob, where only true females should be. And this, and nothing more, strikes us as the true explanation of the supposed hybrid the East Indian gentleman supposes he has found between Sorghum and Maize.
