Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . 804. Ord. IcgliminoSEe {Pulse Family). Herbs, shrubs, or trees,with alternate and usually compound leaves, furnished with stipules. FIG. 796. A flowering branch of Lathyrus palustris, var. myrtifolius. 797. The corolladisplayed : a, the vexillum or standard; i, the alae or wings ; c, the two petals of the carinaor keel. 798. The keel-petals in their natural situation. 799. The stamens and pistil, en-larged ; the sheath of filaments partly turned back. EXOGENOUS OR DICOTYLEDONOUS PLANTS. 413 Calyx mostly of five sepals, more or less united ; the odd sepal in-ferior (Fig. 358). Corolla of five petals, either papilionaceous orregular. Stamens perigynous, or sometimes hypogynous. Ovarysingle and simple. Fruit a legume, various forms of which areshown in Fig. 580, 581, 800-807. Seeds destitute of albumen, orwith a mere vestige of it. — This immense family is divided intothree principal suborders ; viz.: —. 805. Subord. PapilionaceOB (Pulse Family proper), which is charac-terized by the papilionaceous corolla, — the vexillum always exter-nal in aestivation (471, Fig. 392), — ten diadelphous (Fig. 4G1),monadelphous (Fig. 462), or rarely distinct, perigynous stamens,and the radicle bent on the large cotyledons. Leaves (rarely sim-ple) only once compound; the leaflets very rarely toothed or lobed. 806. Subord. CSBSalpineOB (to which Cassia, Cercis, and the Honey-Locust belong) : here the corolla gradually loses its papilionaceouscharacter, and always has the vexillum, or superior petal, coveredby the lateral ones in aestivation ; the stamens are distinct, and theembryo straight. The leaves are often bipinnate. 807. Subord. MimoseSB (a large group, to which the Acacia and theSensitive Plant belong) has a perfectly regular calyx and corolla,the latter mostly valvate in aestivation and hypogynous
