Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . gnified seed, showing the albumen andminute embryo. 432 ILLUSTRATIONS OF THE NATURAL ORDERS. adnate to the 2 - 5-celled ovary; the limb four- or five-cleft ortoothed, or occasionally obsolete. Stamens as many as the lobes ofthe regular corolla, and alternate with them, inserted on the various. Seeds albuminous. — This extensive family dividesinto two principal suborders, viz.: — 839. Suboid. StellateJE (Madder Family proper). Herbs, with theleaves in whorls ; but all except a single pair are generally supposedto take the place of stipules. — Ex. Galium, Rubia (the Madder),&c, nearly all belonging to the colder parts of the world. The rootsof Madder yield the important dye of that name; and those ofseveral species of Galium are imbued with a similar red coloring-matter. 840. Subord. Cinclioneae (Peruvian-Bark Family). Shrubs, trees,or herbs ; the leaves opposite and furnished with stipules, which arevery various in form and appearance. — Ex. Cephalanthus (Button-. brush), Pinkneya, and an immense number of tropical active, and generally febrifugal properties prevail in this largeorder. It furnishes some of the most valuable known remedialagents, among them Peruvian Bark or Cinchona, and Ipecacuanha. FIG. 864. Piece of Rubia tinctoria (the Madder) in flower. 865. The fruit. 866.

EXOGENOUS OR DICOTYLEDONOUS PLANTS. 433 The febrifugal properties of the former depend on the presence oftwo alkaloids,Cinchonia and Quinia, both combined with Kinic Quinquina barks, which are derived from some speci
