    Diagnostic
    Very closely related to C. baluensis and C. holtziana which, if a very broad view of the species were taken, might be treated as subspecies. It differs from them chiefly in the indumentum which may be sparse or copious but is not stiffly erect and in the much gentler (less sharp) and often fewer crenations of the leaflet margins.

    Habit
    Small tree 3–6(–10) m. tall; trunk well defined, though sometimes very short, 12–20 cm. in diameter; outer bark white, peeling in large flakes or small sheets from the blue-green under-bark; slash showing red layers; exudate faintly scented; young twigs pubescent, fluted, pale grey, later becoming dark.
    Leaves
    Leaves greyish green, paler beneath than above, pubescent with ± erect hairs, usually ± 0.1 mm. long, but on the veins beneath 0.2–0.5 mm. long; the leaves on short-shoots or in clusters at the ends of twigs, always 3-foliolate, those scattered singly on long-shoots (very rarely seen in herbarium material) sometimes 5-foliolate; petiole up to 4 cm., ± as long as, or rather longer than the lateral leaflets which are obliquely ovate, orbicular, elliptic or obovate, broadly cuneate below, rounded or, less often, broadly pointed apically, crenate-serrate with 5–8 teeth on each side or with 3–5 teeth only on the distal part of the upper side, up to 20 mm. long, 7–17 mm. wide; terminal leaflet obovate, with 7–13 teeth on each side, gradually attenuate below into a stalk-like base 2–6 mm. long, length including the base 20–30 mm., breadth 12–25 mm.
    Inflorescences
    Inflorescences pubescent, appearing with the leaves; bracts linear, caducous 2–4 mm. long; ♂ flowers 6–15 together in groups of subumbellate cymes; peduncles 2–6; pedicels 2–3 mm. long.
    Calyx
    Calyx densely pubescent, receptacle ± 1.3 mm., tube ± 0.3 mm., lobes narrowly triangular, attentuate to the tip, 1.7–2 mm. long.
    Corolla
    Petals pale yellow, sparsely pilose outside, oblanceolate, 3 mm. long, 1.3 mm. wide.
    Filaments
    Filaments 2 and 1 mm., anthers 0.5 and 0.4 mm. long.
    Flowers
    Female flowers usually single, less often 2 or 3 together on a peduncle 1–3 mm. long; pedicels 2–8 mm.
    Female
    Female flowers usually single, less often 2 or 3 together on a peduncle 1–3 mm. long; pedicels 2–8 mm.
    Fruits
    Fruit sparsely puberulous or almost glabrous, ellipsoid or ovoid-ellipsoid, slightly flattened, 10–10.5 × 8–9.5 × (3–4 + 4–4.5) mm.; pseudaril a cup embracing the lower quarter or third of the stone, with 2 broadly triangular obtuse lobes covering most of the faces and no sutural lobes; stone smooth, flattened-ellipsoid with gently convex faces, ± 7 × 4–6 × (1.5 + 2) mm.
