The photograph was taken about two weeks after the last pollination was made. period is very short or is entirely ab- sent. With the death of the top there is usually continued development of the daughter bulbs, and growth of feeding roots. Without doubt the best means of securing healthy and vigorous bulbs, of many species at least, is to grow them locally either from seed or by vegetative propagation, and to trans- plant so that the bulbs are only out of the ground for a short time, when they are most nearly dormant. Such excellent varieties as the Easter Lily, the Madonna Lily, Henry's Lily, the Lance-leaved Lily (L. speciosum), and the Regal Lily are readily grown from seed. Frequently blooms may be had on seedlings in two years—cer- tainly they may be had in three years. The growing and breeding of lilies from seed presents many interesting possibilities, not only to the commercial growers of bulbs but to the amateur gardener as well. In lilies the bulb habit of growth does not in the least affect seed pro- duction. To obtain seed one must either grow self-compatible plants or grow strains that are cross-compatible. When this is done, seed in abundance may readily be obtained except in the relatively few cases of impotence from intersexes or Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York Botanical Garden.
