Bulbs are said to be timicated when they consist of concentric layers each entu-e, and enclosing all within it, as in the Onion. But the more common variety is the scaly bulb, consisting of tliickened concave scales, connected to- gether at the base, as the lily, tulip. b. The bulb is renewed annually, at tlie approach of winter, by the develop- ment of new bulbs in the axils of the scales, which increase at the expense of the old.^ c. Btdblets^e small, aerial bulbs, formed in the axils of the leaves upon the stem, wUch, when matured, fall to the ground, take root, and produce a perfect plant. The tiger-lUy (Lihum bulbiferum) is an example, also several species of the onion. Such plants are tenned FIG. of the stem;-1, Allium; 2, Arum; 3, Solanum tuberosum; ^ San- guuiana; 5, a spinous branch. ' 179.

The TUBER,is an annual, thickened portion of a subter- ranean stem, provided Avith latent buds (called eyes), from Avhich nevvT plants arise the succeeding year. It is the develop- ment of buds, and the fact of its origin with the ascending eocis, tliat places the tuber among stems instead of roots. The pota- toe is an Please note that these
