A widely distributed species, with rather constant characters, considering its 

 range. I am unable to distinguish any constant characters by which the four 

 species recognized by Van Tieghem, Lanthorus pentapetalus, L. spicifer, L. cumingii, 

 and L. blumeanus, can be separated from Loranthus pentapetalus Roxb.
