Annual, biennial, or perennial herbaceous plants, with sinuate, 

 pinnatifid or pinnate, alternate leaves, without stipules. Flowers 

 few or solitary, terminal, regular or nearly so, perfect. Sepals 2, 

 concave, caducous (falling ofi"), with valvular prefloration. Pe- 

 tals 4, imbricate, rumpled in prefloration. Stamens usually inde- 

 finite, free. Anthers two-lobed, introrse. Ovary fi'ee, consisting 

 of two or several carpels, one-celled, with false (imperfect) disse- 

 piments, rarely two-celled by a complete dissepiment. Ovules 

 numerous. Stigmas sessile, persistent. Fruit dry, many-seeded, 

 usually round or oblong, rarely linear, opening by a series of 

 pores under the disc of the stigmas, sometimes not opening, but 

 transversely divided into one-seeded joints. Seeds usually very 

 small, in an oleaceous (oily) fleshy perisperm. Embryo straight, 

 very small, at the base of the perisperm. Radicle towards the 

 hilum.
