Unit I: 
Systematics

Goal and essence of taxonomy; systems of classification – artificial, natural and phylogenetic. Current systems of classification – Takhatajan, Cronquist, Thorne, APG System (Judd 2002).

Unit II: 
Botanical nomenclature

The international code of Botanical nomenclature – Principles, rules and recommendations. Principle of priority; typification; rule of valid and effective publication; author citation; retention and rejection of names; change of rank; nomenclature of fossils, lichens, fungi and hybrid & cultivated plants.

Taxonomic hierarchy:  Concept of genus and family, primitive vs Advanced characters, homology, analogy, parallelism, convergence, horizontal and vertical classification, monophylly and polyphylly.
