ALABASTBA BORNEENSIA. 221 



longis, obtuse acuminatis, basi. acutis, in siccitate brunneis vel 

 pallidis, utrinque nitidis, nervis obsoletis; floribus in a,xillis 

 superioribus fasciculatis, dense confertis, multibracteolatis, 5- 

 nieris, circiter 3 mm. longis; calycis glaucescentis longitudi- 

 naliter rugosi lobis ovatis, 1 ad 1.2 mm. longis, exterioribus 

 majorihus. 



A small glabrous tree 3 to 6 m. high, the branches and 

 branchlets slender, castaneous or reddish-castaneous when dry, 

 the branches terete, bark more or less flaky, the branchlets 

 smooth, distinctly 4-angled, the internodes less than 1 cm. in 

 length. Leaves coriaceous, opposite, ovate to ovate-lanceolate, 

 7 to 1-1- ram. long, -1 to 7 mm. wide, smooth, shining, brown or 

 pale when dry, base acute, apex blunt-acuminate, the nerves 

 and reticulations entirely obsolete, eglandular; petioles' 1 mm. 

 long or less. Flowers yellowish, crowded in dense fascicles in 

 the upper axils, the fascicles about 5 mm. in diameter. Calyx 

 about 3 mm. long, narrowed below, glaucous, longitudinally 

 rugose, not at all verruculose, the lobes 5, ovate, acute to obtuse, 

 1 to 1.2 mm. long, the outer ones distinctly larger than the 

 inner. Petals orbicular, about 1 mm. in diameter. Bracteoles 

 subtending the flowers numerous, 1.5 to 2 mm. long, oblong- 

 obovate to subspatulate, obtuse, more or less concave. 



'Sarawak, Mount Santubong, Foxworthy hok, June 7, 

 1908, on a forested ridge, altitude about 300 meters, known to 

 the Malays as mortap. 



A species manifestly belonging in the same group as 

 Eugenia zeylanica, Wight, for which Miquel proposed the sec- 

 tion name Leptomyrtus. It is distinguished from all hitherto 

 described forms of this group by its very small leaves, the 

 nerves and reticulations being entirely obsolete. It is most 

 closely allied to Eugenia besukiensis, (Hassk.) Merr., from 

 which it is at once distinguished by its smaller entirely nerve- 

 less leaves. 



Eugenia moultonii, sp. nov. § Syzygium.

 distinctis, nervis primariis utrinque circiter 20, tenuibus, in- 

 distinctis, rectis; inflorescentiis axillaribus terminalibusque, 1 

 ad 2 cm. longis, paueifloris, inferioribus plerumque 3-floris,
