Discuss Floriculture and Landscape Plants

2. Scientific Classification of Plants
Taxonomy – the science of classifying and identifying organisms such as plants

3. Scientific Names
Scientific names are necessary because the same common name is used for different plants
Latin is the language used for scientific classification

4. Scientific Names
Carlos Linnaeus is a Swedish botanist that developed the binomial system of naming plants by using two Latin words to indicate the genus and the species

5. Scientific Names
In the scientific name, the first word is the genus (first letter is capitalized)
Plants in the same genus have similar characteristics
In the scientific name, the second word is the species
Plants in the same species consistently produce plants of the same types
If there are additional words after the species, they indicate the variety or cultivar (variety var or cultivated variety or cv)

6. Plant Kingdom
The broadest category of scientific classification is the Kingdom (plant or animal)
The broadest category of the plant Kingdom is Division or Phylum

7. The four most important divisions of the plant Kingdom are:
Thallophytes – algae, fungi, lichens

8. The four most important divisions of the plant Kingdom are:
Bryophytes – true mosses, liverworts

9. The four most important divisions of the plant Kingdom are:
Pteriophytes – ferns, horsetails, club mosses

10. The four most important divisions of the plant Kingdom are:
Spermatophytes – seed bearing or flowering plants
Gymnosperms – seeds are not in an ovary (cone)
Angiosperms – seeds are enclosed in an ovary (flowering)

11. Common Plant Genus Pinus – pine Acer – maple Ilex – holly Ficus – fig
Cornus – dogwood
Quercus - oak

12. Scientific Name Example
White Oak’s genus and species would look like:
Quercus alba
