This document provides an introduction to plant systematics. It discusses how early botanists like Theophrastus and Pliny helped establish the field by classifying plant species. It also mentions how Charles Darwin influenced the field with his theory of evolution in Origin of Species. The document defines key terms like plant systematics, taxonomy, and plant taxonomy. It discusses how plants are classified based on characteristics like reproductive structures. It also covers identification of plants using features of leaves, flowers, fruits, and stems. The document mentions the International Code of Botanical Nomenclature which established the binomial naming system for formally naming plant species.

Introduction to plant systematics Sarah Ashfaq
Introduction Early botanists such as Theophrastus, Pedanius Dioscorides, and Pliny started the science of plant systematics, as each of them classified many plant species in their books. Charles Darwin was the main influence on the science, with the publication of The Origin Of Species. He may have been the first to use phylogeny, and called the rapid development of all the higher plants within recent geological time "an abominable mystery".
Theophrastus Pedanius Dioscorides Pliny Charles Darwin
Definition Plant systematics Plant systematics deals with interrelation between plants and their evolutionary descent. Systematic Botany The systematic botany is the study of identifying, naming and classifying all plants. Taxonomy Arrangement by rules. Plant Taxonomy Classification/Arrangement of plants following certain rules or principles.
Classification It is the arrangement of plants into groups having common characteristics. Characteristics such as their reproductive structures, physical features, and evolutionary history.

Identification It is recognition of certain characters of flowers, fruits, leaf or stem and the application of a name of plant with those particular characteristics. How to Identify a Plant Note the climate and region. Observe stems and branches. Note the leaf shape and size. Check the leaf arrangement. Note fruits and flowers. Look for barbs, hairs, or thorns. Note the smell. Check the roots.

Nomenclature Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy. Plant taxonomy is concerned with grouping and classifying plants.
International Code of Botanical Nomenclature The code is based on a two-name (binomial) system developed by the famous botanist Linnaeus. Each plant is given a first name and last name, generally based in Latin, that is unique to each species.
