The genus Coffea, distinguished from Psrjchotria (where 

 the fruit is unknown) by the aestivation Of the corolla and 

 the form of the stipules, and from Faramea by the ovarium, of 

 which the cells are completely^ distinct, appears to contain 

 several distinct groups and perhaps genera, but until the fruit 

 of the several species shall be better known, it is impossible 

 to define them satisfactorily. (?ardnei-'s Nos. 185 and 19^, 

 both from Rio Janeiro, appear to me to belong to it.
