ON THE APGCINEiE. 



Obs. The only true species of Nerium are, N. 

 Oleander, odorum, and probably salieinum, 

 Forsk. 



Nerium Zeylanicum and antidysentericum, 

 form a very distinct genus, which I have named 

 Wrightia. N. coronarium is probably a Taber- 

 namontana, and N. divaricatum, from an exa- 

 mination of the specimen in Hermann's Herba- 

 rium, on which this species entirely rests, I be- 

 lieve to be the same plant. Nerium obesum, 



Forsk., seems to be sui generis : it cannot, at 

 least, be a Nerium.
