Inflorescence a terminal or axillary raceme, panicle, thyrse or umbel. Flowers 4–6-merous, uni-or bisexual or polygamous. Calyx usually lobed or more rarely closed in bud and rupturing irregularly. Petals imbricate or contorted in bud. Stamens with an adaxial, usually hairy, scale having a free tip. Disc annular to subcylindrical, very variable in size, sometimes partially enveloping the ovary. Ovary of 4–6 carpels, carpels free or coherent; style 1 or styles coherent; stigmas stellately spreading or one single slightly lobed or capitate stigma. Fruits 1–6 from each flower, drupaceous or woody, often compressed, bicarinate or not, sometimes very large.
Shrubs or small trees, all parts quite bitter to the taste. Leaves alternate, odd-pinnate; petiole and rachis conspicuously winged and articulated; leaflets 5-7, opposite, entire, sessile.
