Botany. 434 TUMAKIACEjE—CEUCIFEEiE. calyx separates in the form of a calyptra, resembling an extinguisher of a candle. Sangmnaria canadensis, Blood-root, or Puccoon, has emetic and purgat;ive properties. Order 10.—;,the Fumitory Family., (Polypet. Hypog.) Sepals 2, caducous. Petals 4, cruciate; one or both of the two outer gibbous at the base, the two inner cohering at the apex. Stamens hypogy- nous, usually 6, diadelphous ; anther of middle stamen of each parcel bilocular, outer ones unilocular. Ovai-y free, 1-celled ; style filiform; .stigma with 2 or more points ; ovules amphitropal. Fruit either an achsenium, or a 1-ceUed 2-seeded, or 2-valved many-seeded pod. Seeds crested; albumen fleshy; embryo minute, eccentric.—Herbaceous plants, with a watery juice, and alternate multifid leaves. Although at first sight very unlike the Poppy family, the Fumitories resemble this order in their deciduous sepals, in their seeds, and, in many cases, in their fruit The two outer unilocular stamens of each parcel may be considered as forming one perfect stamen, thus making the whole number four. They are found chiefiy in northern temperate latitudes. Two are found at the Cape of Good Hope. They are usually scentless, and are said to be bitter and diaphoretic in their properties. The tuber of Corydalis bulbosa has been used as a substi- tute for Birthworts in expelling intestinal worms, and as an emmena- gogue. Authors notice 18 genera, including 134 species. Examples— Fumaria, Corydalis, Dicentra (Dielytra), Hypecoum. Order 11. — Oeucifek^, the Cruciferous or Cresswort Family, Brassicacese of Lindley. {Polypet. Hypog.) Sepals 4, deciduous, the. Fig. 670.
