This species seems to be most closely related to S. Schwerinii Rehder and S. 

 caloneiira Rehder. The former differs chiefly in the more pubescent leaves with only 

 13-16 pairs of veins, in the longer petioles and in the much smaller fruit, while the 

 latter is easily distinguished by its narrower more oblong leaves mostly broadest 

 about or above the middle and gradually narrowed at the base, with fewer veins and 

 longer petioles.
