What is the difference between Natural System and Phylogenetic System?

Natural System:

1. Classification based on form and natural relationship among plants.

2. Based on one or few natural characters.

3. Characters chosen were permanently retained sexual or vegetative ones.

4. Does not give any idea on origin and evolution of different taxa.

Phylogenetic System:

1. Classification based on natural, evolutionary and genetic relationship among plants.

2. Based on many such characters.

3. Characters chosen have evolutionary significance from primitive to evolved conditions.

4. Gives some idea on origin and evolution of different taxa.
