In some respects this species resembles Meliosma Fordii Hemsl but 

 differs remarkably in its long-peduncled, exserted panicles and its 

 rounded, obtuse, or somewhat acute but not acuminate leaves which are 

 minutely and shallowly subfoveolate on both surfaces, the ultimate 

 reticulations being about 0.3 mm. in diameter.
