Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. FLOWER FLOWER 593 leaves are formed, the intervening; parts grow very lit- tle, and so do not separate the suocessiye leaves or cir- cles of leaves. The torus is more or less broadened or elongated to permit the suitable growth of the crowded. Torus and fruit of Raspberry. leaves. In the strawberry it is high, dome-shaped (Pigs. 826, 827); in the raspberry the torus remains (S, Fig. 828) when the little drupes are removed; in the rose it is urn-shaped, bearing the leaves on the edge and inner face ; in the mouse-tail it is much elongated. When a nujaber of tiowers are crowded together their leaves are developed from a common torus, as in sun- flower and chrysanthemum and other members of the Compositte (Fig. 829). The common torus may be broad and flat, with the flowers scattered over it, as in Dorstenia (Pig. 732); or even hollow, as in the fig (Fig. 821), with the minute flowers on the nearly enclosed inner face. Floral haves.—The leaves of the flower form two series; the outer protective and attractive leaves, the floral leaves, and the inner sx>orangial leaves. The floral leaves are usually distinguishable into an outer set, the calyx, and an inner set, the corolla. The calyx leaves, when separate, are called sejjals, and the corolla leaves petals. The sepals are more or less different from the petals in size, shape and color. They are oftenest green, and usually smaller and simpler than the petals. In the bud they usually completely cover the inner leaves. The sepals and petals oftentimes do not remain distinct throughout their development, but each set grows as a single piece; a fact which has been made the basis of classification of the angiosperms.
