A point on the stem from which one or more leaves arise. In the mature stem the nodes are usually well separated by internodes, which elongate through the action of * intercalary meristems. However in some plants, e.g. rosette plants and grasses, the nodes remain close together giving these species their characteristic growth form. The pattern of vascular connections between the stem and leaf at the node may be described as unilacunar, trilacunar, multilacunar, etc. depending on how many leaf gaps are left in the stele. |
