9 Solitary Flowers Flowers that form singly on upright stalks Ex: tulips, roses, daffodils
10 Inflorescence A flower that is made up of several florets Flowers have a branching pattern from the main stemThe main stalk of an inflorescence is a peduncle, stalks that support the florets are called pedicels
11 Types of Inflorescence Spike:Has an elongated inflorescence on the main stem.Ex: liatris, gladiolus
12 Types of Inflorescence Raceme:Similar to a spike except florets aren’t directly attached to the stemEx: delphinium
13 Types of Inflorescence Corymb:Has a flat top or slightly convex shapeHas main stem with pedicels of unequal lengthEx: yarrow
14 Types of Inflorescence Cyme:Broad and flat toppedHas divisions that arise below a terminal flowerEx: Bird of Paradise
15 Types of Inflorescence Umbel:Flower cluster that is easily recognizedSimple umbel has single pedicelled flowers all arising from the top of the main stem. Ex: agapanthusCompound umbel has secondary umbels arising from main stem. Ex: Queen Anne’s Lace
16 Types of Inflorescence Spadix:Thick flower spike surrounded by a conspicuous bract.The spathe (bract) is often mistakenly identified as the flowerEx: Anthurium
17 Types of Inflorescence Catkin:Slender , scaly-bracted inflorescence found on woody plantsEx: Willow, alder, birch
18 Types of Inflorescence Head Flower:Short, dense cluster of flowers in a flat patternEx: sunflowers
19 Leaf PartsThree main leaf parts:BladePetioleStipules
20 Three main leaf parts: Blade (the leaf itself) Petiole (the leaf stalk that connects the leaf blade to the stem)Stipules (the two appendages at the base of the petiole)Any of these parts may be lacking. For example, when there is not a petiole, the leaf is sessile (attached directly to the stem).
21 Leaf TypesLeaf type will affect texture, style and form in a floral design.Simple leaf: a leaf with a single bladeCompound leaf: a leaf with more than one blade (leaflets).Leaflets are the smaller blades that make up a compound leaf and may be arranged in a variety of ways/See page 135, Figure 9-21.Draw and label the four leaves shown.
22 Leaf Vein Patterns Vein patterns in leaf blades are called venation TypesparallelpalmatepinnateSee page 136, Figure 9-22.
24 Leaf Vein Patterns Label the three types of leaf venation: 1. ____________2. _____________3. ____________Name ______________
25 Leaf Shapes See page 137 Figure 9-24 Basic outline of the blade make up the shape of the leafEx: oblong, linear, pelate, ellipticDraw three different types of leaf shapes
26 Leaf Margins Page 137 Figure 9-25 Edge of the leaf blade is called a marginThe appearance of the margin can affect the texture of a designEx: entire, undulate, serrate, lobedDraw three different types of leaf margins
27 Post-harvest Physiology & Metabolic Processes: Please have your books open to pg 137Background:Once plant material is harvested, the plants are still metabolizing.When flowers are cut, the supply of water and mineral nutrients for normal metabolic activity id temporarily cut off. And the flowers and foliage continue to lose water.Unless the water loss is inhibited, wilting and loss of turgor will result.Turgor (cell rigidity and firmness)
28 Water Uptake & Transport Cut flowers need to drink water, which carries sugars and other compounds and helps keep flower parts turgid (firm).Flower stems have a plumbing system called the xylem, which is made up of tiny vessels. The xylem is the water-conducting tissue that carries water up the stem, to the leaves, and to the flower.Please draw figure 9-27 on page 139 and describe what is happening in the picture.Phloem is another plumbing system, but it is the food-conducting tissue.
