Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . - many-celled with the placentae in the axis. Calyx eitherfree from the ovary or more or less adherent to it. Petals and stamensinserted on the calyx; the latter mostly definite. Seeds albuminous, nu-merous. Pistils of the same number as the sepals. Crassulace^e. Pistils fewer than the sepals, more or less united. Saxifragace^e. Group 20. Ovary compound, 2- (rarely 3-5-) celled, with a single ovule sus-pended from the apex of each cell. Stamens usually as many as the pet-als or the lobes of the adherent calyx. Embryo small, in hard albumen. * Summit of the (often 2-lobed) ovary free from the calyx; the petals and sta- mens inserted on the throat of the calyx. Hamamelace^:. * * Calyx-tube entirely adherent to the ovary. Stamens and petals separable into two dry carpels. Flowers umbellate. Umbellifer^:.Fruit drupaceous, usually of more than two carpels. a 1 - 2-celled drape. Flowers cymose or capitate. Cornace^;. 380 ILLUSTRATIONS OF THE NATURAL 737. Ord. RannilCUlaceaB {Crowfoot Family). Herbaceous, occa-sionally climbing plants, with an acrid watery juice, and usuallypalmately or ternately lobed or divided leaves, withoutstipules. Calyx of three tosix, usually five, distinctsepals, deciduous, except inPaeonia and five to fifteen, oroften none. Stamens indefi-nite, distinct. Ovaries nu-merous, rarely few or soli-tary, distinct, in fruit becoming achenia (Fig. 566, 567) or follicles(Fig. 579, 648, 649), or in Aetata a berry. Embryo minute, at thebase of firm albumen (Fig. 650, 610). — Ex. Ranunculus, the But-tercup (Fig. 645), which has regularflowers with petals. Clematis (Vir-gins Bower, which is the type of atribe), Anemone (Fig. 411), Hepatica(Liver-leaf), &c. have no petals, butthe calyx is petaloid. In these the flow-ers are re
