CUNONIACE.E. I. WEINMANNIA. 



197 



and divided petals, and a superior and inferior ovarium. In the 

 series of natural affinities the Philadelpheae clearly follow the 

 Cunoniacece, with which they correspond in habit ; and in Bau- 

 era and Belangera the stamens are indefinite, and the seeds of 

 Caldcluvia have a striking analogy to those of Philadelphus. 

 The styles both in Saxifragacea; and Cunoniacece are often 3, 

 and in Cornidia of the Flora Peruviana that number is always 

 constant. 



A species of Weinmannia is used in Peru for tanning leather, 

 and its astringent bark is employed to adulterate the Peruvian 

 bark. The Indian Weinmannias appear to possess similar 

 astringent qualities.
