Objective: 

This course will enable the students to –

  1. To enable the students identify thrust areas of modern taxonomy without shifting focus from the traditional ones.
  2. To enable students to classify the higher plants based on their taxonomical characters
  3. To introduce various classification (Classical and Modern) methodologies in vogue for Angiosperms
  4. To impart knowledge about the economic importance of higher plants under the taxonomic hierarchy.
  5. To create an exposure on preservation techniques of plants leading to their collection during field trips.

Plant Systematics

On completion of this course, the students will be able to;

CO55: Understand plant classification and recognize the importance of herbarium and virtual herbarium and evaluate the important herbaria and botanical gardens

CO56:  Interpret the rules of ICNafp in botanical nomenclature

CO57:  Analyse terms and concepts related to phylogenetic systematics

CO58: Understand the General  characters of the families according to Bentham & Hooker’s system of classification and learn its merits and demerits
