During the process of fertilization in the Angiosperms it has been shown by the researches of Nawaschin and Guignard that in Lilium and Fritillaria both generative nuclei enter the embryo sac, one fusing with the oosphere nucleus, the other with the polar nuclei (fig.
9, B), or wall- communis (A) and endos threads which are present in the perm of Lilium Martagon wall of the cell (fig.
They are very thick in Viscum album, and are well seen in Phaseolus inultiflorus and Lilium Martagon.
They are present from the beginning of the development of the cell-wail, and arise from the spindle fibres, all of which may be continued as connecting threads (endosperm of Tamus communis), or part of them may be overlaid by cellulose lamellae (endosperm of Lilium Martagon), or they may be all overlaid as in pollen mother-cells and pollen grains of Helleborus foetidus.
LTTERATURE.The following is a list of a few of the more important papers in which further information and a more complete list of literature will be found: Allen, Nuclear Division in the Pollen Mother-cells of Lilium canadense, Annals of Botany (1905), vol.
Xxi.; On the Prophases of the Heterotype Mitosis in the Embryo-sac Mother-cell of Lilium, Ann.
Xxiii.; Fecundation in Plants (Carnegie Institution, 1904); Nawaschin, Resultate einer Revision der Befruchtungsvorgange bci Lilium Martagon und Fritiliaria tenelia, Bull.
The typical genus Lilium and Fritillaria are widely distributed in the temperate regions of the northern hemisphere; F.
A more important work, the Practica seu lilium medicinae, of Bernard Gordon, a Scottish professor at Montpellier (written in the year 1307), was more widely spread, being translated into French and Hebrew, and printed in several editions.
LILY,' Lilium, the typical genus of the botanical order Liliaceae, embracing nearly eighty species, all confined to the northern hemisphere, and widely distributed throughout the north temperate zone.
Elwes (Monograph of the Genus Lilium, 1880), who first tested all the species under cultivation, and has published every one beautifully figured by W.
The word Xeipcov itself, from which lilium is derived by assimilation of consonants, appears to be Eranian (Ibid.
The word "lily" is loosely used in connexion with many plants which are not really liliums at all, but belong to genera which are Madonna or White Lily (Lilium candidum).
Uromyces Erythronii, a rust, sometimes causes considerable injury to the foliage of species of Lilium and other bulbous plants, forming large discoloured blotches on the leaves.
The conventional fleur-de-lis, as Littre says, represents very imperfectly three flowers of the white lily (Lilium) joined together, the central one erect, and each of the other two curving outwards.
The edges of the leaves of Bryophyllum calycinum and of Cardamine pratensis, and the growths in the axils of the leaves of Lilium bulbiferum, as well as the fronds of certain ferns (e.g.
Few bulbs come into the summer flower gardens, but amongst those which should always be well represented are the Gladiolus, the Lilium, the Tigridia and the Montbretia.
Agriculture is spreading but slowly among them; they still prefer to plunder the stores of bulbs of Lilium Martagon, Paeonia, and Erythronium Dens canis laid up by the steppe mouse (Mus socialis).
Here again forests of Coniferae predominate, especially on the northern and eastern slopes; and the other distinguishing features of the flora are gigantic male ferns (Aspidium filix-mas), Paris incompleta (a member of the Trilliaceae), Usnea or tree-moss, box, holly (Ilex aquifolium), Lilium monadelphum and many of the familiar herbaceous plants which flower in English gardens, though here they grow to an altogether extraordinary size - " monkshoods, Cephalaria, Mulgedia and groundsels, among which men on horseback might play at hide and seek without stooping " (E.
