Vernation. 77, of birch leaf; 78, of lilac, (imbricate): T9, cherry leaves, (convoluto) ; 80, dock bud, (revolute); 81, balm of Oilead, (involute). 214. The general vernation is Mosely distinguished in descriptive botany as valvate (edges meeting), and Imbricate (edges overlapping), terms to be noticed hereaftr c. 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 ,2. ve^^lSTTf s . its unfolded margins, as in the privet and iris. Obvolute, or half-equitant, when the outer leaf< embraces only one of the margins of the inner. camore bud. 63 as in the sage. Triquetrous, where the bud is triangular in sec- tion, and the leaves equitant at each angle, as in the Carices. 215. The principle op budding. 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, Cicutabulbifera, and Aspidium bulbiferum, the axillary buds spon- of"; taneously detach themselves, fall to the ground, and become new plants. These remarkable little bodies are called bulblets. 83,84, Showing the process. Plea
