Phylogenetic system of classification is based onArtificial systems (e.g., that of Linnaeus) were based on a few morphological characters such as the androecium structure.
Natural systems (e.g., Bentham and Hooker) were based on natural affinities, considering many external and internal features.
Phylogenetic classification systems are based on evolutionary relationships between organisms; they assume that organisms belonging to the same taxa have a common ancestor.
Classification based on chemical constituents is chemotaxonomy.
Hence the phylogenetic system is based on evolutionary relationships.
