Monophyly - Wikipedia
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of taxa which meets these criteria: Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram.

2.4 Phylogenetic Trees and Classification
On a phylogenetic tree, a monophyletic group includes a node and all of the descendants of that node, represented by both nodes and terminal taxa. Thus, a monophyletic group is also a clade (see Section 2.1). A phylogenetic tree illustrating the concept of monophyletic groups, or clades.
