In the former case they are unfolded into branches at once, or in the spring following their formation. But latent buds suspend their activities from year to year, or perhaps are never quickened into growth. 203. Axillary buds become terminal so sooq as their development fairly commences, therefore each branch also has a terminal bud, and, like the main axis, is capable of extending its growth as long as that bud remains unharmed. If it be destroyed by violence or frost, or should it be transformed into a flower-bud, the growth in that direction forever ceases. 204. The suppression of axillary buds tends, of course, to sim- plify the form of the plant. Their total suppression during the first year's growth of the terminal bud is common, as in the annual stem of mullein and in most perennial stems. When axillary buds remain per- manently latent, and only the terminal bud unfolds year after year, a simple, branchless trunk, crowned with a solitary tuft of leaves, is the result, as in the palmetto of our southern borders. 205. A PARTIAL suppression OP Buus occurs in almost all species, and generally in some definito order. In plants with opposite leaves, sometimes one bud of the pair at each node is de- veloped and the other is suppressed, as in the pink tribe (Caryophyllaoea;). When both buds aro developed, the â branches, appearing in pairs like arms, are said to be brachiaie, as in the Labiataa. In many trees the terminal buds are ar- rested by inflorescence each season, and the growth is continued by axillary buds alone, as in the Catalpa and horse-chest- nut. In all trees, indeed, buds are sup- pressed more or less, from various causes, disguising at length the intended sym- metry of tho branches, to the utter con- fusion of twigs and spray. 206.
