  3. 22) Droseraceae • Sundew Family • Insectivorous, glandular herbs • Often of acid bogs • Leaves usually adaxially circinate (appearing to unwind from a spiral on upper side) • Leaves either with sticky glands (the leaf slowly rolls up on an entrapped insect) or sensitive hairs that trigger a snap trap closing on an insect • Sepals, petals, and stamens usually 5; carpels 3, fused, basal or parietal placentation; fruit a capsule

  4. ExamplesDroseraceae • Drosera spp. (sundews) • Dionea muscipula (venus fly trap)

  5. Dionaea muscipula

  6. Drosera spp.

  7. Drosera filiformus – Note the the adaxially circinate leaves

  8. Drosera rotundifolia

  9. Dionea muscipula – l.s. note basal placentation

  10. 23) Polygonaceae • Knotweed Family • Herbs (or shrub, tree, vine) with swollen nodes • Leaves with stipules fused into a tube sheathing the stem (nodal ocrea), or in their absence, flowers in involucrate heads (subtended by bracts) • Flowers usually small • Tepals 6, petaloid often in two series of 3; or sepals 3 and petals 3; or tepals 5 due to fusion of 2 tepals • Fruits and seeds polygonal in shape

  11. ExamplesPolygonaceae • Rheum palmatum (rhubarb) • Polygonum • Polygonella • Rumex (dock, buckwheat) • Eriognum (wild buckwheat)

  20. Homocladium platycladium

  21. 24) Viscaceae • Christmas Mistletoe Family • Epiphytic parasite of tree branches; roots modified to form haustoria • Leaves usually opposite, leathery, veins parallel • Flowers small, perfect or imperfect; perianth of 3 or 4 tepals, inserted on a cup-shaped receptacle; stamens as many as perianth segments • Ovary inferior, fruit a viscous berry

  22. Arceuthobium cyanocarpum – staminate and pistillate plants
