Flower Sepals…Calyx Petals…Corolla Stamens…Androeciumanther & filament Pistils…Gynecium stigma, style, ovary (egg)
Magnoliaceae Primitive flower - blending of flower parts; spirally arranged fossils, embryology, modern plants Degeneria Carpel - primitive pistil
Placentation Parietal Axial Free Central
Number of carpels 1. Lines on the outside of the pistil2. One stigma lobe per carpel 3. Number of locules (if not free central
Inflorescence Types arrangement of flowers on the flowering stemSolitary - one flower per peduncle Terminal: Axillary:
Inflorescence Types arrangement of flowers on the flowering stemMany Flowered - More than one flower per inflorescence spike: Raceme:
Inflorescence Types arrangement of flowers on the flowering stemMany Flowered - More than one flower per inflorescence Panicle: Much branched Corymb: Outer flowers oldest
Inflorescence Types arrangement of flowers on the flowering stemMany Flowered - More than one flower per inflorescence Cyme: Middle flowers oldest Umbel: All come of Peduncle apex
Inflorescence Types arrangement of flowers on the flowering stemMany Flowered - More than one flower per inflorescence Head: Dense, rounded with many sessile flowers
Inflorescence Types Determinate: Indeterminate:Oldest flowers toward the top Indeterminate: Oldest flowers toward the bottom
Stem - Branch Bud - embryonic branch
Leaves - Margins
Hairs - Glands
Woody vs Herbaceous Woody - Shrubs (fruticose) Treesarboreous - well developed trunk arborescent - > 20 feet but main trunk short Vines- climbing with tendrils
Woody Perennials Apical Dominance Age of Branch Age of Tree
Fruit (Pericarp) ripened ovaryExocarp, Mesocarp, Endocarp
Fruit Types Fleshy: Hip - cluster on achenes in a hypanthiumPome - from a compound, inferior ovary with a thick & fleshy receptacle
Fruit Types Fleshy
Fruit Types Dry Indehiscent:Achene - 1-seeded, connected to the pericarp at a single point Samar (Shizocarp)- 1-seeded winged achene
Fruit Types Dry Indehiscent:Acorn - 1-seeded, with a hard coat & surrounded by a cap of hard bracts Nut - 1-seeded, hard coat
Fruit Types Dry Indehiscent
Fruit Types Dry Dehiscent:Capsule - multiple carpeled, opening in various ways Follicle - 1-carpelated fruit splitting down 1 side
Fruit Types Dry Dehiscent:Legume - 1-celled, 1-carpelated, splitting on 2 sides Sillicle (sillique)- short, 2-locular fruit with each half separating from one another with a thin septum
Fruit Types Dry Dehiscent
Fruit Types Simple - from one ovary Compound Aggregatefrom many pistils Accessory fleshy receptacle Multiple from many flowers
Life Cycle Durations Annual - one year of less Biennial - 2 yearsPerennial - more than 2 years
Plant Structure CoalescenceConnate - Same kinds of structures coalesce Adnate - Different kinds of structures coalesce
Plant Structure CoalescenceSynpetalous - Corolla tube Synsepalous - Calyx tube Apetalous ?
Plant Structure CoalescenceFilaments: Monodelphus - all stamens coalesce Diadelphus - 2 stamens coalesce Polydelphus - many stamen coalesce
The Fruits The frut is the devoloped , fertilized, mature ovary or ovaries of a single flower. Function: to protect and nourish the seed during development.
