Leaves simple, alternate, penninerved, glabrous; petiole not winged; blade generally elliptic to elliptic oblong, papyraceous to coriaceous, margin entire or faintly serrulate, apex acuminate, venation prominent below. Inflorescences panicles, terminal or subterminal, many flowered, pulverulent to pubescent; bracts and bracteoles velutinous outside, caducous. Pedicel not articulate. Calyx lobes 3-4, small, triangular, connate at the base forming a funnel-shaped or slender urn-shaped tube. Petals 4, longer than calyx lobes, loosely attached to the staminal tube. Stamens numerous, inflexed in bud, multiseriate, the inner ones shorter and sterile, the basal part connate into a tube, the entire tube caducous, glabrous; anthers small, versatile, basifixed, ovoid to ellipsoid, bilocular, longitudinally dehiscent. Disc intrastaminal, consists of the vertex of the ovary and a ring-like rim. Ovary inferior, biloculate, ovules ascendent, 2 in each cell, placentation central. Styles slender, as long as stamens; stigma simple or pin-head shaped. Fruits indehiscent, not winged, generally inserted at the terminal end of the peduncle, crowned by the persistent calyx; pericarp fibrous to woody.
