CUNONIACE Æ. 
and divided petals, and a superior and inferior ovarium. In the 
series of natural affinities the Philadélpheæ clearly follow the 
Cunonidcee, with which they correspond in habit; and in Bau- 
éra and Belangéra the stamens are indefinite, and the seeds of 
Caldclivia have a striking analogy to those of Philadélphus. 
The styles both in Saaifragdcee and Cunonidcee are often 3, 
and in Cornidia of the Flora Peruviana that number is always 
constant. 
A species of Weinménnia is used in Peru for tanning leather, 
and its astringent bark is employed to adulterate the Peruvian 
bark. The Indian Weinmdnnias appear to possess similar 
astringent qualities.
