Species Description - Tree; young shoots minutely appressed puberulous at first, soon glabrous, reddish-brown or greyish-brown, scaling, without lenticels. Leaves densely clustered, spirally arranged, 8.5-13 × 4-5.8 cm, cuneiform to oblanceolate, apex obtuse to rounded, base abruptly rounded or truncate, chartaceous, glabrous or with some sparse residual minute indumentum near the base; venation eucamptodromous, thin marginal vein present, midrib flat or slightly raised on the upper surface, secondary veins 9-11 pairs, parallel, straight or slightly arcuate; intersecondaries absent; tertiaries oblique, numerous; finer higher order reticulum (lens). Petiole 2-3 mm long, not channelled, broadened laterally, minutely appressed puberulous. Fascicles axillary and below the leaves, 2-5-flowered. Pedicel 1.3-1.5 cm long, slender, with sparse minute appressed hairs. Flowers bisexual (?). Sepals four, 4-5 mm long, lanceolate, apex acute or obtuse, outer pair with sparse minute appressed indumentum outside, inner pair glabrous outside, all glabrous inside. Corolla cylindrical, 8-8.5 mm long, tube 5-5.5 mm long, lobes four, ca. 3 mm long, broadly oblong, apex rounded, glabrous or with a few scattered long appressed hairs outside. Stamens four, fixed about one-third up the corolla tube; filaments 4-4.5 mm long, glabrous; anthers ca. 1.5 mm long, broadly lanceolate-sagittate, glabrous. Staminodes four, 2.5-3 mm long, subulate, glabrous. Disk absent. Ovary globose, four-locular, sparsely puberulous; style ca. 5.5 mm long after anthesis, included glabrous; style-head simple. Fruit unknown. Field characters. Tree to 10 m high and 20 cm diam. with fluted bole; bark shallowly fissured, pale brown, slash pinkish brown with some white latex.
