ALABASTEA BORNEENSIA. 211 



A glabrous tree, the branches pale-gray, terete, the 

 youngest branch] ets brown, somewhat compressed or terete, 

 2 mm. in diameter or less. Leaves opposite, coriaceous, ob- 

 long-elliptic, 6 to 9 cm. long, 2.5 to 3.5 cm. wide, apex 

 rounded, base rounded or slightly cordate, sessile or nearly so T 

 subolivaceous or brownish when dry, somewhat shining, the 

 upper surface obscurely pitted, the lower glandular-punctate ; 

 lateral nerves 10 to 14 on each side of th<* midrib, slender, not 

 prominent, obscurely anastomosing. Flowers axillary and ter- 

 minal, fascicled or in short, few-flowered racemes, the in- 

 florescences not exceeding 2 cm. in length. Buds about 1 cm. 

 long, obovoid. narrowed below into the distinct pseudo-stalk, 

 terete, brown, glandular, the calyx-tube at the mouth 6 to 7 

 mm. wide, in hud closed by the calyptra which apparently 

 represents the calyx-lobes, the calyptra orbicular in outline, 7 

 mm. in diameter, radiate-reticulate, subconic, obscurely apicu- 

 late, when fallen leaving the truncate calyx-rim. Petals 4, 

 free, orbicular to obovate, 4 to 4.5 mm. long, falling with the 

 calyptra. (top of the calyx) but not at all united with it. 

 Stamens very numerous, their filaments 10 to 12 mm. long, the 

 flower in full anthesis about 1.8 cm. long and wide.

This species is remarkable in its floral structure, in the 

 calyptrate calyx resembling Eugenia operculata, Eoxb., and the 

 Philippine E. clcrnsa, C. B. Rob., but remote from both of these 

 in its vegetative and inflorescence characters. Eugenia oper- 

 culata, Eoxb., is placed in the section Syzygium, where the 

 present species cannot belong because its petals, although falling 

 as a calyptra inside the apex of the calyx, are entirely free. 

 The three species, Eugenia operculata, E. claasa, and E. para- 

 do.ra are more distinct from Eugenia (§ Eueugenia), Jambosa, 

 and Syzygium, which some authors maintain as distinct genera, 

 than are these sections (or genera) from each other, yet unless 

 the genus Eugenia be split up into very numerous genera dis- 

 tinguished from each other by very minor characters, there is 

 no warrant for considering the species above described, and 

 the others discussed herewith, as a distinct generic type.

Species E. grandi similis, sed differt floribus multo mino-
