Species

Characteristics

A tree to 30 m. tall, often with a large grey extremely straight unbranched cylindrical bole of up to 15 m. tall and 1 m. diameter, generally dividing into a small number of main branches which themselves each branch in a similar manner.. Leaves up to 80 cm. long, generally imparipinnate, less often paripinnate; leaflets (3–)6–7(–12) pairs, chartaceous to coriaceous, lanceolate to ovate (occasionally very broadly ovate), often markedly straight-edged, up to 14(–17) cm. long and up to 5.5(–7.5) cm. wide, acute to acuminate, generally apiculate, rarely retuse, rounded or obtuse, with a subcordate, truncate or rounded, rarely very broadly cuneate, occasionally slightly oblique base, and entire occasionally slightly undulate, generally very narrowly inrolled margins, densely stellate-tomentose when young, irregularly glabrescent to some degree (especially above) later; petiolules of paired leaflets (0–)5(–14) mm. long.. Inflorescence-branches of three orders (fig. 4/2), racemosely borne, pubescent to tomentose, often irregularly glabrescent, sometimes galled (see p. 1); primaries up to 70 cm. long, 3.0–6.5 mm. diameter; secondaries up to 3–7(–12) cm. long, 0.7–1.7(–2.0) mm. diameter; tertiaries (pedicels) up to 4 mm. (not exceeding 2.5 mm. in Flora area) long, 0.3–0.8(–1.0) mm. diameter.. Flowers greenish-yellow to cream; style, 2, persistent in fruit.. Fruits ovoid to obovoid, occasionally ellipsoid, shortly cylindroidal or subspheroidal, 3.5–6.0 mm. long by 3.0–4.5 mm. maximum width, generally ribbed and markedly flattened, glabrous or very sparsely stellate-hairy.. Fig. 4/1–5, p. 13.
More
Leaflets (3)6–7(12)—paired, up to 12(17) × 5(7·5) cm., sessile or with petioles of up to c. 10 mm. long, coriaceous (often strongly so), lanceolate-ovate (the terminal leaflet often broader and more ovate than the lateral paired ones); apices acute, often with a small mucro, rarely obtuse and emarginate; bases rounded to subcordate (rarely subcuneate); margins entire to slightly undulate, more or less convolute, becoming leathery and subglabrous, the lower surface more or less densely tomentose.
Primary axes up to 40(70) cm. long, tomentose to subglabrous, bearing numerous laterals of 8(12) cm. long, densely crowded with flowers, but elongating somewhat as the fruit matures.
A tall tree up to 30 m. high with a long unbranched trunk, eventually dividing into primary and secondary branches in a very regular manner.
Leaves up to 80 cm. long, regularly pinnate, usually imparipinnate though examples lacking the terminal leaflet are encountered.
The large leaves bunched at the top of the rather few branches; leaflets white-tomentose beneath, dark green above
Fruit broadly-ovoid to subglobose, 3–4(6) × 3–5 mm., glabrous to slightly pubescent, somewhat ribbed.
Pedicels up to 5 mm. long; petals greenish to creamy white, flowers honey-scented.
Stylopodium somewhat depressed, styles widely divergent for most of their length.
Inflorescence a complex of compound racemosely arranged racemes.
A tree, 20–50 ft. high, rarely to 100 ft.

Environment

Mainly found in mountain forests into the bamboo zone, often in clearings and regrowth. It also occurs in rainforests, lowland forests, riverine forests and mountain grasslands, frequently being left standing when forest is cleared for cultivation.
