Branches clothed with a dull-grey bark; young branchlets up to 3 in. long, terete, glabrous. Leaves lanceolate, oblong-lanceolate or ovate-elliptic, gradually acuminate to an acute or mucronate apex, cuneate at the base, 4–9 in. long, 1 1/4–3 1/2 in. broad, entire, chartaceous, glabrous and somewhat dull on both surfaces; lateral nerves 10–15 on each side, very slender, looped and anastomosing freely well within the margin, distinct and slightly prominent on both surfaces; petiole 2–3 lin. long, deeply grooved on the upper side, wrinkled, otherwise glabrous; stipules ovate-lanceolate, small, soon falling off. Male racemes axillary on the young shoots, solitary or subsolitary, about 2 in. long; axis slightly flexuous, sulcate, glabrous; bracts ovate, slightly keeled, ciliate; pedicels about 3/4 lin. long, glabrous. Sepals 4, oblanceolate, 3/4 lin. long, ciliate towards the apex, otherwise glabrous. Stamens 5–7; filaments 1/3 lin. long, glabrous; anthers ellipsoid, nearly 1/2 lin. long, mucronate. Rudimentary ovary short, bifid, glabrous. Female racemes solitary or geminate towards the base of the young shoots or on the two-year-old wood, 1 1/2–2 in. long; axis angular or deeply sulcate, glabrous; bracts ovate or ovate-triangular, about half the length of the pedicels, ciliate; pedicels stout, angular, 1 lin. long, glabrous. Sepals 5 or 6, ovate-anceolate or lanceolate, gradually acuminate, 3/4 lin. long, ciliate. Ovary 2-lobed (resembling 2 shoulders), each lobe very slightly bifid, glabrous; styles connate for about 1/2 lin. at the base, linear and undivided, glabrous, 3 lin. long. Fruits not seen.
