1 Solanaceae: Solanales Habit: Herbs, shrubs, trees, vines Hairs: Often stellate, prickles or spines Leaves: Simple, alternate, exstipulate (sometimes deeply lobed), may be adenate to stem Inflorescence: Determinate, cymose or solitary Flowers (overall): Showy, bisexual Floral Symmetry: Radial Calyx: 5 connate sepals, often persistant Corolla: 5 connate petals, rotate to tubular, plicate (folded), lobe end turned inward or reflexed

2 Androecium: 5 epipetalous stamens, alternate, connivient anthers (touching) Gynoecium: 2 connate carpels, tilted, superior ovary, terminal (gynobasic) style Placentation: axile Fruit: Berry or capsule Pollination regime: Bees, wasps & flies (pollen sp. only). Moths, butterflies (nectar sp.) Interesting Species: Tomato, eggplant, tobacco, jimsonweed, petunia Gestalt: "5-5-5-2" Hairs, plicate corolla, berry, rotate flower, connivient anthers Solanaceae: Solanales

41 Apocynaceae:Gentianales Gynoecium: 2 connate carpels (apically united), ovary superior or half- inferior Placentation: Marginal Fruit: follicle, capsule, drupe or berry, seed with tuft of hair Pollination regime: great diversity, specialized mechanisms, 3-zone style (deposition, sticky middle, reception) [get nectar from base of stylar head and deposit pollen, get sticky, pick up pollen on the way out] Other comments: Contain poisons, poison arrows Interesting Species: Vinca, Oleander, Dogbane Gestalt: Milky sap, opposite leaves, contorted bud, "5-5-5-2", glandular calyx. 3-part style
