In most of the points described the germination of the Wallflower may be regarded as typical of that of the Dicotyledons generally. For example, the exit of the radicle through the micropyle is very constantly the first stage in germination. The behaviour of the cotyledons, however, differs much in different members of the Class. In some plants, such as the Broad Bean (Vicia Faba), the cotyledons never rise above the ground at all, but serve simply as storehouses of food, the first assimilating leaves being those of the plumule. In seeds, again, which when ripe contain abundant endosperm, the first duty of the cotyledons is to absorb the food which the endosperm contains, and they do not emerge from the seed (if they do sa at all) until this has been accomplished. CHAPTER II Type II THE WHITE LILY (Lilium candidum, L.) It matters little which of the common kinds of Lily we take for our type. The following description refers in the main to the White Lily, but the general Figs. 52 and 53 are of Lilium auratum, and some of the other figures refer to different kinds. The White Lily grows wild in Southern Europe, Persia, and the Caucasus, and is one of the commonest Lilies cultivated in gardens. I. EXTERNAL CHARACTERS A. Vegetative Organs In cultivation, Lilies are usually raised from lulih. A bulb is really a large underground bud. It consists of a short conical stem, covered with densely-crowded, spirally-arranged, thick scale-leaves, which completely coat the surface, leaving no internodes between them. The base of the bulb produces fibrous roots. The bulb is that part of the plant which persists at all times, in winter as well ...
