1A slender part between two nodes or joints, in particular.
- In type II divergence, the evolutionary rate for a specific site is accelerated somewhere along the basal internode that connects the two subfamilies.
- The branching pattern observed in Figure 1 shows that the early eutherian radiation was rather rapid (note the short basal internodes coupled with long terminal branches).
- The articulated colonies of Crisia fragment into their constituent internodes after decay of the elastic joints.
1.1 Botany A part of a plant stem between two of the nodes from which leaves emerge.
- The shoot, especially in the upper part, was elongated in OB plants with longer internodes but the same leaf number.
- The upright clump of leaves observed on 11 December 1987 was a vestige of the future upright, leafy stem with very short internodes between the leaves.
- Buds in the axils of the bracts expanded and repeated the pattern; each had a prophyll that remained in the bract axil, a long internode, then a succession of leaves with shorter internodes and a terminal spikelet.
Mid 17th century: from Latin internodium, from inter- 'between' + nodus 'knot'.
