505			_a1. Introduction Biological classification Need and importance of taxonomy Aims of taxonomy 'Taxonomy' and 'Systematics' 2. The Evolution of Theories of Biological Classification Conceptual Development of Pre-Darwinian Taxonomy Essentialism Nominalism Empiricism Conceptual development of post-Darwinian taxonomy 3. Problems in Evolutionary Taxonomy Deducing phylogenetic relationships: the concept of 'primitive' and 'advanced' Monophyly and polyphyly Parallelism and convergence Homology and analogy Presentation of phylogenetic relationships The theoretical basis of plant classification: a critical evaluation 4. The Historical Development of Classificatory Systems Early classifications The classical period Glimpses of plant science in ancient India The modem period Post-Darwinian systems 5. Taxonomic Structure 6. Concepts of Taxa Concept of species Nominalistic species concept Taxonomic, essentialistic or typological species concept Biological species concept Phylogenetic species concept Alternative species concepts Infraspecific categories Supraspecific categories The concept of the genus . The concept of the family " Categories above family level 7. The Material Basis of Systematics The concept of character Correlation of characters Character weighting Character variations Isolation Geographical or ecological isolation: a pre-requisite for reproductive isolation Sympatry as the test for biological species Post-mating mechanisms Incompatibility Post-zygotic mechanisms Speciation 8. Sources of Taxonomic Characters Comparative morphology Comparative anatomy Palynology Apertural morphoforms Exine stratification and ornamentation Pollen association Pollen nuclear number Embryology Cytology Chromosome number Chromosome morphology Chromosome behaviour Cytochemistry Banding patterns Phytochemistry Biosynthetic pathways in relation to taxonomy Systematic insight from other aspects of biology Modern systematics: the synthesis unachieved 9. Plant Nomenclature Major rules Typification (Arts. 7-10) The rule of priority Limitations of priority (Arts. 13-15) Effective and valid publication Author citation (Arts. 46-50) Retention, choice and rejection of names and epithets Rejection of names (Arts. 62-72) Nomenclature of hybrids (Arts. H.1-H.10) What is there in a name? Why change?
