In order to render this treatise as complete as possible, besides 

 giving a description of the group itself, I thought it important 

 to add the characters of the genera. It is immaterial whether 

 the Empetrece are to be regarded as a section of the Eupihor- 

 hiacecB^ or as constituting a separate family. Their intimate 

 affinity has, I trust, been satisfactorily shewn ; and it also ap- 

 pears clearly evident, that the EuphorbiacecB, StacJchousece, Ce- 

 lastrince, and Rhamnece, must follow each other in a natural 

 arrangement, as Mr Brown seems disposed to think *.
