The results were that the roots, or the appendages which would have been roots under natural condi- tions, pushed upward in the form of leaves, as shown In figure 110. This is but another in- stance of the reorganization of cellular matter referred to in a previous chapter. By dividing large, mature bulbs crossways, and inverting the lower section, and planting it in sand, with root surface exposed to the light, sprouts may be obtained in large numbers, each producing a small bulb at its base. The upper half of the bulb may be lightly scarified on the surface, and forced in the same way as though it had not been divided. Irises, Jxias and Fardanthuses are readily propagated by ofilsets, which are produced very freely. The Tigridias have rather small, compact bulbs, many in a cluster, or clump, as shown in figure 111. They must be kept in a warm, dry place during the winter months, and when taken up in the fall the leaves and stems should be left entire, and not cut off until towards spring, or after the bulbs have become thoroughly dried. iMhiatw (Mint Family).—A very large order inostly of herbs, usu- ally with scented foliage. Many of the genera furnish medicinal and economical plants, such as Sweet Basil, Horehound, Lavender, Mint, Patchouly, Rosemary, Sage and Thyme. These are simple garden herbs, all readily propagated by seed, divisions of the roots, or cuttings of the young shoots planted under glass. The ornamental species of ScUvia are mostly natives of warm climates,
