NATURAL HISTORY OF PLANTS. 



two arrangements may even, as in Phoxanthus, 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. SAPINDITS SEEIES. 



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

 dite or polygamous, often with four, more frequently with five parts.

case, a calyx with five imbricate sepals, equal or unequal, and a 

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

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

 with a simple or double petaloid appendage. Inside the petals is 

 seen a circular disk in the shape of a glandular pad surrounding the 

 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 perigynous free filament, and a bilocular introrse 

 anther dehiscing by two longitudinal clefts.^ The gyneeceum, rudi- 

 mentary in the male fiowers, is free, formed of an ovary often with
