A small or moderate-sized evergreen tree of variable leaves and 
inflorescence, pubescence, etc.; branchlets terete, glabrescent; buds 
perulate, densely silky tawny-pubescent as are the innovations. 
Leaves chartaceous or thinly coriaceous, alternate or subopposite or 
subverticillate at the ends of the branchlets; lanceolate or oblong 
or elliptic, sometimes even ovate or obovate, acute or obtuse at 
apex, usually acute at base; upper surface somewhat shining, closely 
but markedly minutely reticulate, glabrous except on the midrib, 
olive green when dry, lower surface paler and varying from glabrous 
to densely grey-pubescent; 10—25 cm. long, 4—10 cm. broad; mid- 
rib broad, pubescent ; main nerves about 8—10 pairs, often branched ; 
transverse nervules irregular and distant; reticulation minutely 
netted; petiole 1—3 cm. long, grey-pubescent to glabrous. Flowers 
in umbellules, in axillary or lateral pedunculate umbels or corymbs 
up to 5 cm. long, the 9 rather shorter than the ¢ ; umbels of 2—5 
umbellules on peduncles 5 mm. (2?) to 12 mm. {¢#) long; umbellules 
12 mm. broad (¢), half that size (2) with 4 concave pubescent in- 
volucral bracts the outer pair orbicular, the inner narrower; flowers 
in each umbellule about 10 to 12, fewer and much smaller in 9? than 
in ¢ ; pedicels about 2 mm. long; perianth-tube short; perianth-lobes 
incomplete, sometimes 0, rarely more than 2 or 3, when present linear 
or spathulate, pubescent. Stamens of ¢ flowers normally 12, some- 
times fewer, sometimes up to 15 or even more, those of outer rows 
10 mm. long, on slender villous filaments and with subquadrate 
anthers ; those of inner rows rather shorter and with a pair of long- 
stalked clavate glands attached at the very base of the filaments ; 
rudimentary ovary often 0, when present conical and very small. 
Staminodes of 2 flowers normally 12 sometimes fewer, often more, 
those of outer rows spathulate, 2 mm. long, with villous filaments,
