Answer

Artificial Classification System

Basis: Superficial morphological characters (habit, flower color, leaf number)

Limitations:

  • Emphasizes vegetative characters (environmentally influenced)
  • Separates closely related species
  • Assigns equal importance to all characters regardless of evolutionary significance

Natural Classification System

Basis: Natural affinities incorporating internal and external features:

  • Anatomy
  • Embryology
  • Phytochemistry
  • Ultrastructure

Example: Bentham and Hooker's system for flowering plants—considered comprehensive and widely used
