Characteristics

Shrub or usually a tree, 5–10(–20) m., trunk straight, sometimes fluted, up to 40 cm. in diameter; bark smooth, greyish.. Branchlets puberulous or glabrous, often purplish brown and with pale lenticels.. Leaf-blade subcoriaceous, variable in shape and size, obovate or broad-elliptic, sometimes lanceolate-ovate, ovate or almost rounded, entire or undulate, or ± deeply glandular-serrate-crenate, 5–10(–12) cm. long, (2.5–)3.5–5.5 cm. wide, subacuminate or obtuse, base broadly cuneate to subcordate, glabrous, or with (sometimes subsetular) hairs on midrib and secondary veins, and quite often in the nerve-axils beneath; lateral veins 6–7(–8) pairs, prominent beneath, reticulation rather coarse and but slightly raised beneath; petiole 0.7–1.5(–2) cm. long; stipules caducous.. Spike-like racemes solitary or aggregated into subterminal or axillary sparsely branched and laxly flowered panicles up to 12 cm. long.. Flowers subsessile, 5–7-merous, greenish-whitish, solitary or often 2 together.. Calyx-tube broadly cup-shaped.. Sepals puberulous on the back, elliptic or ovate, 3.5–5 mm. long.. Petals broadly rhomboid-elliptic or ovate, puberulous dorsally, 3.5–4 mm. long.. Stamens in fascicles of 3 opposite the petals; filaments glabrous or hairy, 3.5 mm.. Disk-glands discoid, tomentose.. Ovary conical, pilose; styles connate to a column below, stigmatic arms free and divergent.. Capsule woody, similar in shape to the ovary, with persistent sepals and petals and usually containing 1 seed 2–3 mm. long and 1 mm. wide.. Fig. 15.
More
Leaf-lamina 5–10 x 3.5–5.5 cm., obovate or broadly elliptic, apex acuminate or rarely rounded, base broadly cuneate or truncate, margin coarsely and irregularly crenate-serrate, lateral nerves in c. 6 pairs, slightly prominent above, prominent below, venation laxly reticulate, glabrous on both sides or setulose-pubescent on the midrib and main nerves below, sometimes with tufts of hairs in the nerve-axils below; petiole often purplish, up to 1.5 cm. long, pubescent or glabrous.
Stamens in fascicles of 3 opposite the petals; filaments 3.5 mm. long, slender, glabrous or sparsely pilose; anthers 0.5 mm. in diam., globose, the thecae free in the lower half and the connective with a blunt glandular process at the apex.
Ovary conical, pilose outside, full of long pilose hairs inside; ovules 6–9, discoid; style 2–3.5 mm. long, columnar, pilose at the base; stigmatic arms divergent, very short.
Flowers in lax, terminal or axillary panicles up to 12 cm. long, the individual flowers 1–2 together and sessile or nearly sessile on the puberulous branches of the panicle.
Fruit capsular, woody and perhaps indehiscent, surrounded by the persistent corolla, pilose, similar in shape to the ovary.
Petals 5–7, 3.5–4 x 2–2.5 mm., broadly rhomboid-elliptic or ovate, subacute at the apex, densely pubescent on the back.
Small tree c. 10 m. tall; young branches pubescent or glabrous, often purplish-brown and with pale lenticels.
Sepals 5–7, 3.5–5 x 1.5–2.5 mm., elliptic or ovate, acute at the apex, densely pubescent on the back.
Seed usually solitary, c. 3 x 2 mm., narrowly ovoid; testa thin and brown.
Disk glands 1–1.5 mm. in diam., discoid, tomentose.
