We based the present genus upon the 2-lobed corolla, which 

 is a characteristic of Pcemna, and the digitate leaves, which 

 are a feature of Vitex. Moreover, , the throat of the corolla is 

 villous before the upper instead of before the midlobe of the 

 lower lip. Yet we conceive, that it may be a doubtful one, 

 since the possibility exists that it may be either a hybrid of 

 a Premna -and a Vitex-species, or a variation of the latter 

 genus.
