EUGENIA Linnaeus 
EUGENIA CLEISTOCALYX nom. nov. 
Jambosa nitida Korth. in Nederl. Kruidk. Arch. 1 (1847) 202, non 
Eugenia nitida Benth., nec Duthie. 
Cleistocalyx nitidus Blume Mus. Bot. Lugd.-Bat. 1 (1849) 84, f. 56. 
Eugenia nervosa Miq. FI. Ind. Bat. 1 1 (1855) 442, non Lour. 
British North Borneo, Villamil 406, 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.
