Taxonomic evidences from Palynology, Cytology, Phytochemistry and Molecular Data

In Taxonomy, evidence is the information used in context for a purpose such as identification or classification. The foundation of plant taxonomy was laid on a number of characters (attributes) of plants and plant groups studied from time to time. Such taxonomic information can be realised in many ways to prove a hypothesis, solve a … Read more
