The calyx is tubular' and gamosepalous, divided above into five dentate teeth, valvate or imbricate in the bud. Usually it divides on anthesis into a certain number of parts marked off by longitudinal clefts, but it often opens into a single spathe-like piece owing to there being but one of these clefts, more or less perfect. The petals are of nearly equal size or unequal, as the vexillary petal may be larger or smaller; the rest differ in form or colour. The prsefloration is imbricate, with the vexillary petal overlapped^ by the two lateral ones, and these again by the an- terior pair. The stamens are in two whorls, superposed to the se- pals and petals respectively; the former set are the larger. Each stamen consists of a filament and an introrse two-celled anther of longitudinal dehiscence.' The gynseceum is borne on a foot of variable length, inserted either in the bottom of the receptacle as in SclerolobiecB, or at a variable height inside its walls, though in this case anteriorly, v^oi posteriorly as in that series. The one-celled ovary contains a variable number* of descending ovules on a placenta looking towards the vexillary petal.' It ends in a style whose stig-. Fia. 85. Inflorescence (f). ' Lined by a layer of glandular tissue, often very thin, bat sometimes, though rarely, thick- ened, especially near the edges. 2 Sometimes only one edge is overlapped. When the posterior sepal is absent, a single sepal occupies the place of the two posterior ones of the resupinate pentamerous flower, and to this it is that the placenta is superposed. ^ The top of the filament is often bent in the bud. The anthers are usually versatile. * Often indefinite. The ovules form two rows, and are descending and anatropous, or incom- pletely campylotropous with their micropyles up- wards and outwards. Certain species have only two or t
