Tetraeugenia Merr. gen. nov. in Journ. Straits Brauch R. Asiat. Soc. Nr. 77 

 (1917) p. 230. — (Myrtoideae — Myrteae - - Eugeniinae.) 



On first studying the above specimen I was disposed to place it in 

 the genus Aphanomyrtus, but it differs so radically from all the described 

 species of this genus and of its synonym Pseudoeugenia, that it mani- 

 festly is worthy of consideration as a distinct generic type. Distinguishing 

 characters are its laxy veined leaves, its four stamens, and its petals being 

 united into a distinct calyptra as in Syzygium. It apparently holds about 

 the same relationship to Syzygium as Aphanomyrtus does to Jambosa.
