Characteristics

Small tree, 3-6(-10) m, trunk up to 15 cm ø, often crooked, or much branched shrub, 2-5 m; branches up to 5 cm ø. Branchlets rather robust, covered distally with a rusty hirsute or almost lanate tomentum as are the petioles. Leaves lanceolate to oblong-elliptic, sometimes partly obovate in the same specimen, apex shortly acuminate, base cuneate, subcoriaceous, dark green, shining and glabrous above, much paler beneath, and set there still towards the maturity with both longish simple or fascicled rufous and fewer minor stellate hairs on midrib and nerves, whereas the veins bear only scattered stellate hairs and the intervenium is glabrous, finally glabres-cent, (5-)6-10(-13) by 2.5-4(-6) cm, rather regularly and deeply (1.5-2 mm) serrate, nerves (15-)17-20(-23) pairs, spreading, ± approximate and subparallel, rather straight from the midrib and partly forked before the edge, ± sharply prominent beneath, veins transverse, ± raised beneath too; petiole robust, 1(-1.5) cm. Racemes panicled or subumbellate, rachis and pedicels covered with a floccose and rusty, almost hirsutulous tomentum, 5-10(-14) cm, flowers rather densely arranged, subpatent. Pedicels rather thickish, 3-5(-6) mm, bracts subulate, 2-4(-6) mm, caducous. Calyx lobes ovate-oblong, subacute, dorsally a little keeled and stellate-tomen-tellous, fimbriate, (4-)4.5-6 by 2.5 mm. Petals obovate, apex slightly erose, thin, glabrous, white or pinkish, (5-)6-7 by c. 3 mm. Filaments glabrous, 2.5 mm; anthers obcordate, base subacute, 1.3 mm. Ovary shortly rufous-hirsutulous; style glabrous, 3-3.5 mm, apex shortly trilobed. Capsule subglobose, 2.5-3 mm ø, pedicel elongate to 10 mm, style slender, 3.5-4 mm. Seeds ovoid, subtrigonous or variously compressed, 0.5-0.8 mm.
