| This axis comprised successive nodes, each having a simple leaf, separated by internodes of variable length. |
| The shoot, especially in the upper part, was elongated in OB plants with longer internodes but the same leaf number. |
| In the studied stem segments, the leaf traces extended for four internodes before the connection with the other vascular bundles. |
| The articulated colonies of Crisia fragment into their constituent internodes after decay of the elastic joints. |
| Growth is controlled by the phytohormone gibberellin and can be largely unidirectional, as in elongating stem internodes, or multidirectional, as in expanding leaves. |
| Eleven centimetre long shoot segments were obtained from internodes of previous year shoots, placed vertically and fitted to plastic tubing. |
