ILLUSTRATIONS OP THE NATURAL ORDERS. 



drous flowers, three partly united pistils with several ovules in each, 

 and large bony seeds, with a straight embryo in scanty albumen. — 

 Ex. Staphylea. 



800. SQl)Ord, Sapindcs (/SbopierryjFami'Zy^rojoer) has alternate, or 

 in the Horsechestnut tribe opposite leaves, without stipules, more or 

 less unsymmetrical or irregular and polygamous flowers, exalbu- 

 minous seed?, and a curved embryo with thickened cotyledons. — 

 Mostly tropical, except the Horsechestnut and Buckeyes (^sculus), 

 which have been deemed a separate family [HippocastanecB). Their 

 very large and fleshy embryo has the cotyledons more or less con- 

 solidated (Fig. 629, 630). The seeds of the Horsechestnut are nu- 

 tritious, but contain an intensely bitter principle which is more or 

 less noxious. Those of JE. Pavia are used to stupefy fish. The 

 root, according to Elliott, is employed as a substitute for soap. The 

 fruit of Sapindus is used for the same purpose, whence the name of 

 Soapberry. 



801. Subord. Acerinese {Maple Family) has opposite (simple or 

 compound) leaves without stipules, a 2-lobed and 2-winged fruit
