Staphylda. The Bladder Nuts 

 are shrubs with usually 3- (3-7-) 

 bladed compound opposite decidu- 

 ous leaves and swollen bladder-like 

 fruit. They have handsome light 

 colored bright green leaves and white 

 or greenish flowers in spring. They 

 are good plants for the shrubbery 

 and do best in somewhat moist rich 

 soil and grow well in partial shade. 

 The parts of the flowers are separate 

 and have 5 sepals, 5 petals, and 5 

 stamens. The fruit is a 2- or 3-celled 

 inflated pod with 1 to few rather 

 large bony seeds in each cell.
