Description
Description - Shrub or small tree up to 20.0 m tall, trunk up to 1.2 m diam, sometimes provided with buttresses; bark sordid gray. Branchlets hairy to villous at tips, more sparsely so on older parts which finally are covered with grayish-brownish cork. Leaves elliptic to oblong-elliptic, sometimes subovate, oblong or subobovate, apex shortly attenuate or subacuminate with bluntish tip or obtuse, base cuneate to rounded, thin-chartaceous or pergamentaceous, initially often hairy in various density on both faces, becoming glabrous above with age, remaining short-pubescent on midrib and lateral nerves, occasionally barbellate beneath, glabrescent beneath too in later stages, or quite glabrous and shining from the beginning, coarsely subserrate- to repand-crenate with blunt teeth, (5-)6-14 cm long, 3.5-8.0 cm broad, lateral nerves (5-)6-8 (rarely -11) pairs rather distinctly looping, slightly prominent on both faces, reticulation of veins and veinlets rather dense and a little raised on both faces; petiole hairy initially, 3-7(-9) mm long. Inflorescences axillary and subterminal, spikelike and simple in general, though sometimes shortly (up to 4 cm) branched or paniculate in their lower part, flexuous-pendent, loosely flowered, all over gray-puberulous, the slender rhachis 6-17 cm long. Flowers (sub)sessile, the lowest ones pedicelled up to 1 mm long, whitish-greenish or creamy-white, odoriferous, (5-)6-7(-8)-merous. Calyx tube depressed-turbinate, base obtuse or rounded, 5-8-sulcate, gray-puberulous or -tomentellous, as are sepals and petals on both faces. Sepals rather narrowly lanceolate, subacute, 1.5-2.0 mm long, 1.0-1.5 mm broad at base. Petals deltoid-ovate, 2.5-3.0 mm long, ca 2 mm broad at base, accrescent in fruit to 4 by 2.5 mm. Stamens in fascicles of (2-)3 or 4; filaments slightly hairy at base, or glabrous. Glands oblate, tomentellous. Free part of the ovary depressed-conical, grayish-villous; styles 3 (rarely 4), free or united at the base into a short column, glabrous, or hairy at base. Seeds oblong-obovoid, 2.5 mm long.
