Those who are interested in the fertilization of flowers would do well to watch how Lilies behave in nature, as well as to experiment with them under culture. Mr. Park-man found the pollen of some kinds had potency for fertilization, but with very little power to stamp its own characteristics on the progeny. The cases of this power were very few, and Lil-ium Parkmani was the chief result. In nature some species show a very prolific character - L. superbum, for instance, usually producing seeds from every flower. On the other hand, Lilium Canadense, even when the flower is crossed by foreign pollen, for which much is claimed by some physiologists, is very often barren.
"The facts which you notice about the fertilization of lilies by the pollen of L. auratum is equally established in regard to fertilization by several other species. In hybridizing L. umbel-latum by L. lancifolium, the only effect produced was to render the resulting flower a complete mule, being in some instances without stamens and with imperfect pistils. The corolla showed no decided effect from the influence of the foreign pollen." •
