 inserted under the flattened 4-lobed disk, oval and re- 

 flexed; stamens 4, inserted between the lobes of the 

 disk; ovary 4-celled, merging into the disk; stigmas 4; 

 ovules solitary and erect in each cavity. The fruit is a

 shrubs, of the warmer portions of the New World. One 

 other species, a small, straggling, or prostrate shrub, 



with spiny-toothed leaves, also grows in southern Florida. 



The name is supposed to be from Rha, the old name of the Volga, and was 



used by Phny for some Old World plant.
