Shrubs and Trees of the Southern States.— IV. 



By John K. Small 



■ 



1. THE EBENACEAE IN THE SOUTH 



Two types with as divergent characters as those possessed by 

 Diospyros Virginiana and the so-called D. Texana, cannot with the 

 least degree of systematic order, be referred to the same genus. 

 The two plants are of wholly different habit, and the flower-struc- 

 ture of the two is so distinct that I cannot understand on what 

 grounds they have been associated with each other in the same 

 genus. The distinguishing characters of the two trees, which I 

 shall treat as two distinct genera, may be compared by means of 



the following synopsis :

 known to occur in the United States.
