Characteristics

Slender tree 20-25 m; tips of the branchlets rufous-tomentose, glabrescent. Leaves lanceolate-oblong or oblong, shortly acuminate and subacute at the apex, attenuate at the base, somewhat de-current in the upper third of the petiole, subcoriaceous, pale olivaceous-green to yellowish and shining above when dry, paler and ± dull beneath, very young ones rufescent-appressedly pilose or-sericeous on the under-surface, glabrescent, finally glabrous, entire or occasionally with a solitary, minute tooth on each side, (6-)7-12(-15) by (2.5-)3.5-5.5 cm; midrib slightly prominent above, distinctly so beneath, nerves 6-7(-8) pairs, rather straight in their lower part, curved upwards and inarching towards the edge, all somewhat raised above, a little more so beneath, reticulations fairly dense and slightly, but well visibly elevated on both faces; petiole rather slender, tardily glabrescent, 1.5-2.5(-3) cm. Racemes axillary and ramiflorous, solitary, sometimes in all the upper leafless axils together forming a terminal panicle, dense, 7-13(-15) cm, rather densely rusty-appressedly hairy all over; rhachis 1.5-2 mm diam. Bracts ovate-lanceolate, subacute, c. 1.5 mm, mostly early caducous. Pedicels mostly in pairs, connate at the base, rarely halfway, rather slender, 3-5 mm. Perianth whitish or cream, sometimes yellow, 17-18(-20) mm, tube 0.8 mm across, limb ellipsoid, 2 mm diam. Anthers 2 mm.
