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.

Sweet Peas

● The names of the Families end in “-aceae.”

Example: Fabaceae – Pea, Legume and Bean Family

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

Uses for Classification

What are some SAE or FFA activities that may require plant classification?

Nursery/ Landscape

Others?

What are some career fields where classification/identification can be used?

• Forestry

• Crop/Fruit Sciences

• Horticulture

• Others?

Practice Makes Perfect

Practice writing the classifications for Roses.

How would we write the order?

Rosales

How would we write the family name?

• Rosaceae

How would we write the genus?

Rosa

How would we write the genus and species for the Rugosa rose?

• Rosa rugosa
