XLII. SAP1NDACE.E. 



Sepals 3-4, usually distinct. Petals 4 (5-0), often bearing internally a scale, separated 

 from the stamens by a disc or glands. Stamens usually 8. Pistil syncarpous : style single, 

 usually 3-fid: ovary 3 (2-4) -celled : cells 1-2 (-3) -ovulate: ovules, if single, mostly erect. 

 Seeds often arillate. Embryo exalbuminous : radicle mostly inferior. — Climbers or woody 

 plants ; leaves mostly alternate, compound (or reduced to a single lamina) ; flowers small, 

 racemose or paniculate, often polygamous. 



Bitter and poisonous substances are common in this Order {Paullinia, Serjanid) • eatable 

 berries or seeds, however, occur likewise {Melicocca, Dodonaa, and the fleshy arillus of 

 Blighia sapida). In some genera there are resinous-aromatic properties (JDodoncea), and 

 others contain a peculiar saponaceous matter {Sapindus).
