▪ His major contribution to Botany is the classification of Plants.
Theophrastus Classified Plants into four Categories on the basis of
their growth habits, Stem Structure and leaves.
• Herbs • Shrubs • Subshrubs • Tress
▪ He divided Plants into two groups trees and herbs. Within these he further
Classified Plants their Stem Structure and leaves, Such as woody herbaceous
Stems and Simple compound and Lobed leaves. He also distinguish between
monocotyledons and dicotyledons based on Seed leaves in the embryo .

The taxonomy of Plants Can be Classified hierarchically Fellows. They are: Kingdom  Phylum  Class  order Family  Genus  Species Botany is the field at biology that deals with detailed view of function and Structure of Plants, Characteristics, existence, adaptation, evolution. It deals with the Plant anatomy ,cell biology, ecology, Bryology, Plant biotechnology Plant genetics and many more.
