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

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

Petals
• Usually conspicuously colored
• Collectively called the corolla
• Normally positioned between sepals and inner flower parts

Stamens
• Threadlike extensions that stand upright from the perianth
• Male reproductive parts of a flower
• Consists of the anther and the filament

Solitary Flowers
• Flowers that form singly on upright stalks
• Ex: tulips, roses, daffodils

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

Types of Inflorescence
• Has an elongated inflorescence on the main stem.
• Ex: liatris, gladiolus

leaf blades are called venation
• Types– parallel– palmate– pinnate
