The woody genera which are as- 

 sembled here as representing the 

 family Saxifragaceae in accord- 

 ance with the views of excellent 

 botanists, are considered by others 

 to. differ too greatly for this union 

 with the herbs, to which they would restrict the name Saxi- 

 fragaceae. These authors employ the family name Iteaceae 

 for the genus Itea, Grossulariaceae for Ribes, and Hydran- 

 geaceae for the remainder. 



Both Jamesia and Edwinia commemorate Edwin P. James, 

 the discoverer of the plant. The first had been used earlier 

 for what is not considered a tenable genus: the second was 

 given under the principle that a name once used pertains 

 always and exclusively in its first meaning. 

 Twigs at first light brown and hairy. J. americana.
