Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . he other hand, they run close to Scrophulariacece andApocynaceaj. — Spigelia Marilandica (the Carolina Pink-root, awell known vermifuge, of somewhat acrid-narcotic properties), andGelsemium (the so-called Yellow Jessamine of the Southern States)are the most conspicuous representatives of the group in this coun-try. The active properties of the family are most conspicuous inspecies of Strychnos. The fatal drug, Nux-vomica, from whichstrychnine is extracted, consists of the seeds of an East IndianStrychnos. Tieute, another frightful poison, is prepared from aJava species, and the Ouari poison of South America, from a thirdspecies. Meanwhile a Brazilian species, S. Pseudoquina, has a harm-less fruit, and its hark ( Copalche bark) is reputed to be an excellentfebrifuge, fully equal to Cinchona. 842. Ord. ValcriaiiacCSD {Valerian Family). Herbs with oppositeleaves, and no stipules. Flowers often in cymes, panicles, or of the adnate calyx two- to four-toothed, obsolete, or else. forming a kind of pappus. Corolla tubular or funnel-form, some-times with a spur at the base, four- or five-lobed. Stamens distinct,inserted on the corolla, usually fewer than its lobes. Ovary one- FIG. 881. Branch of Fedia Fagopyrum. 882. A magnified flower. 883. A fruit. 884. Anenlarged cross-section of the same, and the cotyledons of the seed in the single fertile cell: thetwo empty cells are confluent into one. 885. Flower of a Valerian, with one of the pappus-like bristles of the calyx unrolled. 886. Section through the ovary and embryo ; the bristlesof the calyx broken away. EXOGENOUS OR DICOTYLEDONOUS PLANTS. 435 ovuled, with one perfect cell and two abortive ones. Fruit a kindof achenium. Seed suspended, exalbuminous. Embryo straight,radicle superior.—Ex.
