We are unacquainted with its history ; it does not seem 
to have been before described ; and we have not been able 
to learn even its native country. In gardens it is called 
Chironia trinervis, but it is a totally different plant from the 
Ceylon p usem so named by Linnæus, which appears to be a 
genuine Exacum, as that genus is limited by Dr. Brown in 
his Prodromus. 
The bitterness of the species is most remarkable, even 
mong its bitter neighbours.
