  1. Classification Scientific Names

  2. Binomial Nomenclature • Two name system for naming plants • Used to simplify names • Linnaeus- Swedish Botanist who came up with this system • Taxonomist-a person who identifies and classifies plants

  3. Binomial Nomenclature • Scientific names are used to avoid confusion concerning the names of plants • Example: • Most plants have more than one common name: TIGER LILY is also known as trout lily, adder’s tongue, dog’s tooth violet, and yellow snowdrop • Two completely different plants may have the same common name: In New York, COWSLIP is a marsh loving buttercup like plant, but in England it is a primrose like plant found on dry, grassy slopes

  4. Binomial Nomenclature • Scientific names are expressed in LATIN because it is an international language and was used by early scholars to express plant names

  5. Advantages of Using Scientific Names • Used worldwide • Taxonomist name and classify plants and animals • Plants purchased with accuracy • Helpful in identifying plants • Standard terminology

  6. Taxonomy Chart Hierarchy of Specification • KINGDOM –plant-animal • DIVISION – PHYLUM (used for animals) • CLASS • ORDER • FAMILY • GENUS • SPECIES • VARIETY (cultivar) • FORM • INDIVIDUAL

  7. Scientific Names • Binomial Nomenclature uses the Genus and Species • GENUS • The first term is known as the generic name. • All plants having the same generic name are said to belong to the same GENUS • GENUS is the First Term (NOUN) • GENUS is always capitalized

  8. Species • The second name is the specific name or special name. • All plants with the same specific name belong to the same SPECIES • SPECIES is the second term (adjective) • SPECIES is always lower case • Latin names of plants are italicized because it is conventional to italicize words and phrases that are expressed in a different language

  9. EXAMPLES • Betula ultea “Yellow Birch” • Quercus rubra “Red Oak” • Acer rubrum “Red Maple”

  10. Varieties or Cultivars • There are many forms of the species red maple. • Variety and/or cultivar names allow you to specify which one. • Acer rubrum cv. Autumn Flame • Acer rubrum ‘Autumn Flame’ • Acer rubrum ‘Red Sunset’

  11. Your Turn Acer rubrum cv. Red Sunset Red Sunset is the _____________________ Acer is the __________________________ rubrum is the________________________
