This species is most closely allied to Homalium paniculiflorum Merr. & 

 Metc, of Hainan, which it closely resembles, but from which it may be 

 readily distinguished by its differently shaped, long-acuminate leaves as 

 well as hy being entirely glabrous except for the inflorescences, while the 

 indumentum on the latter is not appressed. The styles and filaments are 

 distinctly shorter than in the Hainan species. Both species are manifestly 

 allied to Homalium cochinchincnsc (Lour.) Druce (H. jagijolium Benth.), 



from which they may be at once distinguished by their paniculate rather 



than strictly racemose inflorescences.
