with forceps. There were no other plants of L. superbum in the 
garden, or in the neighborhood: so that in this case, as in the former, 
fertilization by the pollen of their own species could not take place. 
Seed-pods, large and well shaped, were formed in abundance; but when 
they ripened in October, some of them contained nothing but chaff. 
Others had a few imperfect seeds, while others gave a fair supply of 
seed as good as could be desired. It was sown in pans, germinated in 
due time, and produced several hundred young bulbs; but when these 
came into bloom, not a single flower of them all was in the least dis- 
tinguishable from the pure L. superbum. Of eight different male 
parents, not one had impressed his features on his hybrid offspring. 
Not only in their flowers, but in their leaves, stems, and bulbs, the 
young plants showed no variation from their maternal parent. In the 
following year, I set some of them apart from the rest, and applied to 
them, as to their mother before them, the pollen of several species of 
lilies. This time, the seeds were extremely scanty. A few, however, 
were produced; but the plants and flowers that resulted from them, 
were, to all appearance, L. superbum pure and simple. 
Another subject of experiment was L. umbellatum, which I fertilized 
with the pollen of L. auratum. Seed was produced in abundance, and 
the young plants began to bloom in the second year. Many of them 
were not to be distinguished from the pure L. umbellatum. Others 
showed unmistakable marks of their hybrid origin in the defective con- 
dition of the organs of reproduction, the anthers being abortive or 
wholly wanting, as were also, in a few cases, even the pistils. In some 
instances, the corolla was deformed, some of the petals being absent, 
and others small and ill-shaped. But while the influence of the alien 
pollen was shown in these defects, no features of the male parent 
appeared either in form, color, scent, or manner of growth. 
No lily seems to offer better prospects to the hybridizer than L. lon- 
giflorum. ‘The species itself is not a good seed-bearer in our climate ; 
but one of its varieties, known as L. longiflorum Takesima, bears seed 
very freely. This variety is also distinguished by superior vigor of 
growth, and by the dark markings of its stem. ‘The pure white of the 
large trumpet-shaped flowers seemed peculiarly fitted to receive im- 
pressions of color from an alien parent. I therefore fertilized them 
with the pollen of a deep red variety of L. speciosum. The operation 
was performed under glass and with the greatest care. The seed was
