¨ The first attempt of classification is observed in Chandyogya Upanishad, which classified animals into three categories — Jivaja(Viviparous = giving birth to young ones), e.g. mammals, Andaja(Oviparous = egg lying), e.g. birds, reptiles, insects and worms, andUdbhija (Vegetal origin), e.g. minute animals. Post-Vedic Indian literature, such as Susruta Samhita (600 BC) classified all ‘substances’ into sthavara (immobile), e.g. plants, jangama (mobile), e.g. animals.
¨ Plants were further subdivided into Vanaspati (fruit yielding non-flowering plants), Vriksha (both fruit yielding and flowering plants),Virudha (shrubs and creepers), and Osadhi (plants that die with ripening of fruits).
