  1. Plant Taxonomy: How Plants Are Named Original PowerPoint Created by Howard Henderson Modified by Georgia Agriculture Education Curriculum Office June 2002

  2. OBJECTIVE • To differentiate between scientific and common plant names and explain the binomial system of naming plants.

  3. The student should be able to: • Explain why scientific plant names are used. • Explain the difference between genus, species and variety. • List five plants by their common and scientific binomial names. • Give four examples of family names (both Latin and common).

  4. Scientific names are used to: • Avoid confusion concerning the names of plants. • Scientific names of plants are expressed in Latin because it is a international language and was used by early scholars to express plant names.

  5. Latin names of plants are italicized: • Because it is conventional to italicize words and phrases that are expressed in a different language. • Example - The most commonly known cultivars of Acer rubrum ( red maple) are “Red Sunset” and “Autumn Flame,” which are the most reliable for brilliant reds and a long-lasting display of foliage.

  6. The generic name of the plant is: • Placed first and begins with a large letter. • Examples: Acer-(maple), Papaver-(poppy), Pinus-(pine)

  7. A genus can be defined as: • A group of plants that have more in common with each other than they have with the members of any other genus.

  8. A species can be defined as: • A group of plants that are alike in almost every feature and consistently produce like plants. • Example - Betus lutea is yellow birch (lutea means “yellow”)

  9. TAXONOMIST A person who identifies and classifies plants!
