| System | Basis | Source detail |
|---|---|---|
Artificial | Vegetative or superficial morphological characters. | Linnaeus's artificial system was based on androecium structure; drawbacks include separating related species and equal weightage to vegetative and sexual characters. |
Natural | Natural affinities among organisms. | Considers external and internal features: ultrastructure, anatomy, embryology and phytochemistry; Bentham and Hooker classification. |
Phylogenetic | Evolutionary relationships. | Assumes organisms in the same taxa have a common ancestor. |
