1. August 2008 Nomenclature and Anatomy of Flowers Modified by Georgia Agriculture Education Curriculum Office June 2002

2. August 2008 A complete flower has 4 parts present sepals petals stamens pistils

3. August 2008 Sepal One of the outermost flower structures Commonly small, green, leaflike structures When the sepals and petals appear the same (such as lilies), they are called tepals Collective word for sepals and petals is called perianth

4. August 2008 Petals Usually conspicuously colored Collectively called the corolla Normally positioned between sepals and inner flower parts

5. August 2008 Stamens Threadlike extensions that stand upright from the perianth Male reproductive parts of a flower Consists of the anther and the filament

6. August 2008 Pistils Female reproductive parts of a flower Consists of the stigma, style, and ovary

7. August 2008 Types of Flower Structure Solitary Inflorescence

8. August 2008 Solitary Flowers Flowers that form singly on upright stalks Ex: tulips, roses, daffodils

9. August 2008 Inflorescence A flower that is made up of several florets Flowers have a branching pattern from the main stem The main stalk of an inflorescence is a peduncle, stalks that support the florets are called pedicels

10. August 2008 Types of Inflorescence Has an elongated inflorescence on the main stem. Ex: liatris, gladiolus Spike:

11. August 2008 Types of Inflorescence Similar to a spike except florets aren’t directly attached to the stem Ex: delphinium Raceme:

12. August 2008 Types of Inflorescence Has a flat top or slightly convex shape Has main stem with pedicels of unequal length Ex: yarrow Corymb:

13. August 2008 Types of Inflorescence Broad and flat topped Has divisions that arise below a terminal flower Ex: Bird of Paradise Cyme:

14. August 2008 Types of Inflorescence Flower cluster that is easily recognized Simple umbel has single pedicelled flowers all arising from the top of the main stem. Ex: agapanthus Compound umbel has secondary umbels arising from main stem. Ex: Queen Anne’s Lace Umbel:

15. August 2008 Types of Inflorescence Thick flower spike surrounded by a conspicuous bract. The spathe (bract) is often mistakenly identified as the flower Ex: Anthurium Spadix:

16. August 2008 Types of Inflorescence Slender, scaly-bracted inflorescence found on woody plants Ex: Willow, alder, birch Catkin:

17. August 2008 Types of Inflorescence Short, dense cluster of flowers in a flat pattern Ex: sunflowers Head Flower:

18. August 2008 Leaf Parts Blade Petiole Stipules

19. August 2008 Leaf Types Simple leaf: leaf with a single blade Compound leaf: leaf with more than one blade (leaflets)

20. August 2008 Leaf Vein Patterns Vein patterns in leaf blades are called venation Types –parallel –palmate –pinnate

21. August 2008 Leaf Shapes Basic outline of the blade make up the shape of the leaf Ex: oblong, linear, pelate, elliptic

22. August 2008 Leaf Margins Edge of the leaf blade is called a margin The appearance of the margin can affect the texture of a design Ex: entire, undulate, serrate, lobed

23. August 2008 Assignment With a partner: –Make a PowerPoint or Prezzi about the types of flowers and leaves discussed –Find at least 3 pictures/examples of each
