In contrast, the portion of stem that lies between two successive nodes or joints is
roots form most readily from this point as the node
correspond to an area of

A node is the
the branching points or vertex on on a
phylogenetic tree (cladogram)
which is supported by
synapomorphies, a node is commonly used to
represent the split of one
lineage to form two or more lineages
(internal node) or the lineage at the present time (terminal node).
Node-based Clade: A
clade originating from a particular node on a
phylogenetic tree; a clade encompassing a particular node on a phylogenetic tree and all
branches (internodes) and nodes descended from
that node; a clade whose name is defined using a node-based definition.
