Plant Classification

Taxonomy is the method by which living organisms are identified and named. The taxa of living organisms are based on the rules and principles of common morphological characteristics they share.
The name of a living organism and its place in the hierarchy provides information about related living organisms. For example, vascular plants can be classified into ferns, gymnosperms, and angiosperms, and for plants classified into Oleaceae, Syringa, it is possible to identify the close relationships of plants in the relevant genus.

Important concepts related to classification include identification, naming, and description.
  • Identification is used to determine the name of a plant.
  • Naming is the process of assigning a name to a living organism, and in the case of plants, it is prescribed based on the International Code of Botanical Nomenclature (ICBN).
  • Description is used to describe the morphological features of a living organism.

Purposes of plant taxonomy

  • To provide a way to identify a plant’s name and describe it.
  • To establish a classification system to reflect its strain and relationships.
  • To prepare lists of plants in a region or country to identify their flora.
  • To identify the evolutionary process of plants.
  • To systematically understand the diversity of plants.

Taxonomic category and scientific name

The classification system is composed in a stratified structure that generally comprises domain->kingdom->division->class->order->family->genus->species.
Scientific names are composed of a binominal name, generic name and species epithet, generally followed by an author name (e.g., Hibiscus syriacus L.). The naming rules and guidelines follow the International Code of Botanical Nomenclature.

Family, Genus, Species, Order

Dendrogram

Pedigree refers to the evolutionary history of biota, and aspects of biological evolution are depicted by dendrograms, which are diagrams with branches like a tree.
