When the growing tip withers or falls away, one of the side buds (or lateral buds) ends up being close to the twig tip and substitutes as a terminal bud for next year's growth. Position of buds: Where the twig ends growth by forming a bud on the very tip, a terminal bud is present. These are bundle scars, aiding species identification during Winter.īuds are also found at nodes, usually in axil of leaf petiole and twig or hidden under petiole base, or sunken in twig.

Inside the leaf scar the vascular tissue pattern is seen, usually as dots or bundles of dots. Where a leaf falls from the twig, a leaf scar is left behind. Internodes are intervals of twig between nodes. Sometimes it may be spine-tipped, or merely have a bud at the tip.Ī node is the portion of a twig where vascular tissue exits and enters this is where leaves arise. It usually produces flowers or clustered leaves and lies along the side of a branchlet or branch. The word cane is also used, but cane is also applied to the stems of the genus Rubus, which have true twigs and branchlets.Ī spur shoot is knobby, short, and very slow-growing.

The previous season's growth (last year's twig) is the branchlet, sometimes called a 2nd-year stem.Ī culm is the vertical woody stem of bamboos, which have no twigs. The current or most recent woody growth, forming the ends of a stem, is the twig. To see photographic examples of a term, click the camera next to it in the list of botanical terms.
