node

noun

(L. nodus: knot) The part of a plant stem from which one or more leavesm roots, shoots, or flowers may arise. The nodes at the stem apex are very close together and remain so in species of monocotyledons that form bulbs. In older regions of the stem they are separated by areas of stem called internodes. A node will contain one or more buds, and is sometimes represented by a swollen or constricted ring, or by a distinctleaf scar.
