2. Why are classification and scientific names important?
For specificity and accuracy
Example:
Hemerocallis Common Names
- Daylily
- Lily
- Ditch Lily
- Lemon Lily

3. Carolus Linneaus (aka Karl von Linne)
Swedish Botanist
May 23, 1701 – Jan. 10, 1778
He published Species Plantarum in 1753.
He based his plant classification system on the plant’s method of reproduction and structure of reproductive parts.
‘Introduced’ binomial nomenclature. Species Plantarum is the starting point of the binomial system of nomenclature.

6. Kingdom Plantae is divided into 12 Phyla based on reproductive and vascular characteristics.
1. Bryophyta: Mosses
2. Hepatophyta: Liverworts
3. Anthosphyta: Hornworts
4. Lycophyta: Club mosses
5. Psilophyta: Whisk Ferns
6. Equisetophyta: Horsetails
7. Pterophyta: Ferns
8. Cycadophyta: Cycads
9. Ginkgophyta: Ginkgo
10. Coniferophyta: Conifers
11. Gnetophyta: Ephedra, Gnetum, Welwitschia
12. Angiospermophyta: Seed Plants (monocots and dicots)

7. Example: Butterflyweed (Asclepias tuberosa)
Kingdom: Plantae (all plants)
Phylum: Angiospermophyta (all flowering plants)
Class: Magnoliopsida (Dicotyledons)
Order: Gentianales (all plants with united petals and fused reproductive parts)
Family: Asclepiadaceae (plants with a specific pattern of fused reproductive floral parts)
Genus: Asclepias (all milkweeds)
Species: tuberosa (a specific kind (species) of milkweed with orange flowers and tuberous roots)

8. Plant Evolutionary Theory
Lower Plants
Spore bearing plants with and without vascular systems are ‘Lower Plants’
Higher Plants
Seed-bearing plants with vascular systems are ‘Higher Plants’
Gymnosperms and Angiosperms are broad categories of seed bearing plants.

9. Gymnosperms
Gymnosperms have seeds with no covering (ie: a fruit or a seed coat). They bear woody cones that hold the seeds.
Gymnos means naked, sperm means seed: gymnosperm = naked seeds
There are 700 living species placed into four divisions: conifers, cycads, ginkgos, and gnetales (such as Ephedra).

10. Angiosperms
Angiosperms were the last of the seed plant groups to evolve.
Angiosperms all produce flowers containing the sexual reproduction structures.
The angiosperms (angios=covered, sperm = seed) produce fruits and seeds. There are presently 235,000 known living species.

11. Primitive Versus Advanced Floral Characteristics
Flower parts many, more than ten
Flower parts free (not united or fused)
Superior ovary
Flowers with radial symmetry
Advanced
Flower parts few, ten or less
Flower parts united or fused
Inferior ovary
Flowers with bilateral symmetry
