MYRTACEAE 



EUGENIA Linnaeus 

 EUGENIA CLEISTOCALYX nom. nov. 



Jambosa nitida Korth. in Nederl. Kruidk. Arch. 1 (1847) 202, non 

 Eugenia nitida Benth., nee Duthie. 



Cleistocalyx nitidus Blume Mus. Bot. Lugd.-Bat. 1 (1849) 84, f. 56. 



Eugenia nervosa Miq. Fl. Ind. Bat. 1 1 (1855) 442, non Lour. 

 British North Borneo, Villamil £06, July 13, 1917, on river banks, 

 local name alag-alag-sulu. 



The type was from Borneo, and Miquel also credits the species 

 to Sumatra; from Loureiro's description it has nothing to do with 

 Eugenia nervosa Lour., where it was placed by Miquel. The species is also 

 the type of Blume's genus Cleistocalyx, and it is worthy of note that so 

 far as striking differential characters are concerned, in this case the 

 peculiar, calyptrate, circumscissly deciduous calyx-limb, Cleistocalyx is much 

 more sharply differentiated from Eugenia than are Jambosa and Syzygium, 

 and hence has stronger claims to generic recognition than either of these 

 groups. 



EUGENIA ALCINAE Merr. in Philip. Journ. Sci. 10 (1915) Bot. 216. 



British North Borneo, Tawau, Villamil 371, May 28, 1917, on the 

 banks of the Sempang Tiga River, at low altitudes; Jesselton, Yates 71, 

 October 8, 1917. 



Both specimens are an excellent match for the type, which was from 

 northern Palawan.
