It would naturally be thought that this slight but evident impression of the character of the male parent might be deepened by iteration. That was tried next year, when the flowers of several of these plants were fertilized with the pollen of L. auratum...

For instance the pure white of the perianth of L. longiflorum came out unstained in the progeny raised by a crossing with L. speciosum / and the herbage was equally unaffected ; but in that or the next generation " distinct evidence could be seen of the action of alien pollen" in the changed color of many of the anthers, and in the abortion of others. They also showed differences of habit among themselves, some...
