The general vernation is loosely distinguished in descriptive botany as valvatc (edges meeting), and imbricate (edges overlapping), terms to be noticed hereafter. The val- vate more often occurs in plants with opposite leaves. Imbricated vernation is Equitant (riding astraddle), when conduplicate leaves alternately embrace—-the outer one the next inner, by go. vernation of Sy. its unfolded margins, as in the privet and iris. Obvolute, or half-equitaut, when the outer leaf< embraces only one of the margins of the inner, as in the sage. Triquetrous, where the bud is triangular in sec- tion, and the leaves equitant at each angle, as in the Cariccs. 215. The principle of buddixg. Each leaf-bud may be regarded as a distinct individual, capable of vegetating either in its native position, or when removed to another, as is extensively practiced in the important operation of budding. 216. Bulblets. In the tiger-lily, Cicuta bulbifera, and Aspidium bulbiferum, the axillary buds spon- of ; taneously detach themselves, fall to the ground, and become new plants.
