Objective 3.03 Discuss floriculture and landscape plants

Taxonomy The science of classifying and identifying plants Scientific names are used because the same common name is used for different plants in different areas of the world.

Karl von Linne Swedish botanist that developed the binomial system of naming plants using two Latin words to indicate the genus and species. Linne changed his name to the Latin name Carolus Linneaus.

Scientific Names Latin is the language used for scientific classification. The first word is the genus (first letter capitalized) and the second word is the species. If there are additional words after the species, they indicate the variety or cultivar (variety – var. or cultivated variety – cv.)

Genus vs. Species Plants in the same genus have similar characteristics. Plants in the same species consistently produce plants of the same type.

Scientific Classification The broadest category of scientific classification is the Kingdom--either plant or animal. The broadest category in the plant kingdom is division or phylum.

Divisions The four most important divisions of the plant kingdom are: Thallophytes – algae, fungi, lichens Bryophytes – true mosses, liverworts Pteriophytes – ferns, horsetails, club mosses Spermatophytes – seed-bearing or flowering plants

Spermatophytes Contains flowering or seed-bearing plants Two subdivisions are: Gymnosperms – seeds not in ovary (cones) Angiosperms – seeds enclosed in ovary (flowering plants)
