Identifying and Classifying Plants
By Kelly Dawkins
Today’s Objectives
●
Learn the common methods used to identify and classify plants
●
Learn the proper methods for writing plant names
●
Learn basic terms used to group plants
●
Learn about vocabulary used to distinguish plants within a species
Why Do We Classify Plants?
● Plants are classified in several different ways.
● A plant name shows their relationship to other plants.
● It also tells us about its place in the plant world.
● Only the family, genus and species are needed for
average identification.
Basic Plant Categories
● Class
● Order
● Family
● Genus
● Species
Class
● Gymnosperms: Plants which don't produce flowers
○ What are some examples of gymnosperms?
● Angiosperms: Plants which produce flowers
Gymnosperms
Angiosperms
Class: Angiosperms
● Dicotyledons (Dicots)
o Plants with two cotyledon leaves
o Four to five floral parts
● Monocotyledons (Monocots)
o Plants with one cotyledon leave
o Three floral parts
Order
● A group of related Plant Families
o classified by their differences from a common ancestor.
● The names of the Orders end in “-ales.”
Examples: Liliales- Lily Order
Family
● Each Order is divided into Families.
● These are plants with many botanical features in common.
● Usually the highest classification used.
● The names of the Families end in “-aceae.”
Example: Fabaceae – Pea, Legume and Bean Family
Sweet Peas
Genus
● It’s the normal name that you give a plant.
● The plants in a Genus are often easily recognizable as belonging to the
same group.
● Similarity of flowers and fruits is the most widely used feature, although
roots, stems, buds, and leaves are also used.
● The name of the Genus should be written with a capital letter and either
underlined or italicized.
Example: Magnolia
Species
● This is the level that defines an individual plant.
● The name will describe a feature of the plant
o flower color, size or shape of leaves, etc.
● The Genus and Species name are used to identify that specific plant.
● The name of the Species should be written after the Genus name,
uncapitalized and either underlined or italicized.
Example: Ranunculus flammula

Practice Makes Perfect
Practice writing the classifications for Roses.

•
Rosales
How would we write the family name?
•
Rosaceae
How would we write the genus?
• Rosa
