Tested in the same way I found the white varieties of the following annual plants also quite true: Chrysanthemum coronarium, Godetia amoena, Linum usitatissimum, Phlox drummondi, and Silene Armeria. I cultivated it, in large numbers during five succeeding generations, but was never able to find even the slightest indication of a reversion to the red prototype.
A hybrid-bean between Phaseolus nanus and P. multiflorus, and some hybrids between the yellow daisy, Chrysanthemum segetum and the allied Chrysanthemum coronarium or ox-eye daisy which also arose spontaneously in my garden between parents cultivated at recorded distances, might further be noted. Further details of these experiments need not be given.
This last was like that species which grows in our woods; but it was insipid. I brought the roots with me to Fort Marlborough, where it lingered a year or two after fruiting and gradually died.* I found there also a beautiful kind of the Hedychium coronarium, now ranked among the kaempferias. It was of a pale orange, and had a most grateful odour.
With Chrysanthemum coronarium and blue-bottles this figure is often announced to be only about 50%. No doubt it is partly due to impurities, caused by vicinism, but it is obviously improbable that the effect of these impurities should be so large. Some cases of partial reversion may be interpreted in the same way.
