Leaves:
Leaves ovate or obovate to oblong, (5-)7- 12(-15) by (2¼-)3-6 (-7½) cm, (4-)5-8-nerved; rather sparsely appressed- hairy, soon glabrescent, with slightly sunken midrib, faintly prominent to faintly sunken nerves, and faintly prominent to indistinct venation above; rather sparsely appressed-hairy, soon glabrescent, with slightly to faintly prominent nerves and venation beneath. Petiole 8-17 mm.
Inflorescences:
Inflorescences terminal, downward passing into axillary, sometimes 2 together, (1½-)3-8 (-12) cm, (5- )10-30(-100)-flowered. Pedicel 1½-4 mm.
Flowers:
Sepals 1 & 2 oval to orbicular, 2-4 by 2-3.2 mm, 4 & 5 transverse-oval, 1.8-3.2 by 2.2-4 mm, rather densely appressed-hairy outside (hairs 2-branched, up to 900 µ total length). Corolla white, 6-9½ mm, tube 2-3 mm; midpetaline field 1.8-4 by 1.3- 2.8 mm, rather densely appressedhairy (hairs 2-branched, up to 1400 µ total length); lobules 2½-4½ by (1½-3 mm, rather thick, with faintly visible venation, entire to irregularly crenulated at margin, coherent above the midpetaline field for up to 1 mm. Stamens inserted ½-l mm
above the corolla-base; filament 1.5- 1.8 mm long, 0.3-0. 7 mm broad at the base; anther 1-2 mm long, 0.4-0.8 mm broad , 0.4- 0.6 mm thick, acuminate (sterile acumen 0.3-0.7 mm) at apex, cordate at base. Ovary 0.8- 1.7 by 0.8-1.5 mm, glabrous; stigma conical, with 5 distinct ridges.

In the Philippine specimens thefruits are scurfy over the whole surface, in the Javanese ones the lower partis smooth. (The Bornean collection is in flower.) What the taxonomic value ofthis character is can not yet be decided because of the small number ofavailable specimens, particularly in the intermediate area.
