Characteristics

Small tree, 4-5 m, Leaves elongate-oblanceolate, rarely oblong, 17-34 by 5-9 cm, cuneate at base, narrowed to subrotundate at apex and abruptly narrowly caudate, cauda 1-4 cm, acute, chartaceous, glabrous, not shining, obscurely grey-brown above when dry, similar or subcastaneous below; midrib relatively slender, prominent below, impressed above; primary nerves 25-30 pairs, strictly parallel, sharply raised beneath, subbullately impressed above, conspicuously arcuate-anastomosing toward the margin; petiole 1-1.5 cm by 2-4 mm, fulvous-pubescent at first, finally glabrescent. Inflorescence 2-4 cm, few-flowered, grey-sericeous. Flowers only known in bud stage: disk-lobes about 30, glabrous, epustulate; style glabrous.
