NATURAL HISTORY OF PLANTS. 



two arrangements may even, as in Pho.vanthus, be met with in one 

 and the same species. The flowers, small and numerous, are col- 

 lected in very ramified compound clusters; they are pretty fre- 

 quently polygamous. 



III. SAPINDUS SEEIES. 



In Sapindm^ (fig. 351-353), the flowers are regular, hermaphro-

 corolla of five alternate petals, equally imbricated or twisted, naked 

 internally or furnished at the point of junction of the claw and limb,

 stamens. These are often ten in number, superposed, five to the 

 sepals and five smaller ones to the petals, each formed by an hypo- 

 gynous or slightly perigyuous fi'ee filament, and a bilocular introrse
