Morphology General Habit

Medium or large tree up to 30 m. high; crown flattened; bark smooth, very rarely rough, grey; young branchlets finely and shortly brownish-pubescent, soon glabrescent and usually deep- or blackish-purple, ultimately grey-barked.

Morphology Leaves

Leaves: pinnae 5-7(8) pairs (rarely only 3 on occasional reduced leaves), each pinna ± narrowing upwards; leaflets of 2 distal pairs of pinnae 9-16(17) pairs, mostly c. 10-20(25) x 4-8(13) mm., obliquely rhombic-quadrate to rhombic-subfalcate, auricled (or sometimes not, but not in our area) on the proximal side, obtuse to acute at the apex, subglabrous or somewhat pubescent on the midrib and margins, rarely, especially when young, some occasional hairs on the primary lateral nerves; raised venation beneath lax.

Morphology Leaves Stipules

Stipules and bracts at base of peduncles lanceolate, up to c. 6-7 x 2-2·5 mm.

Morphology Reproductive morphology Inflorescences

Peduncles puberulous or finely pubescent; bracteoles mostly caducous, linear, inconspicuous, (1)2-6 mm. long, normally shorter than the flower-buds except when extremely young.

Morphology Reproductive morphology Flowers

Flowers subsessile; pedicels puberulous or sometimes glabrous, 0·25-0·75(1) mm. long.

Morphology Reproductive morphology Flowers Calyx

Calyx 2·5-5 (very rarely indeed 1·5-2·5) mm. long, minutely, shortly and rather appressedly brownish-pubescent to subglabrous outside.

Morphology Reproductive morphology Flowers Corolla

Corolla 6·5-12 mm. long, minutely pubescent outside, white.

Morphology Reproductive morphology Flowers Androecium Stamens

Staminal tube exserted c. 1·5-2·8 cm. beyond the corolla, white below, crimson above.

Morphology Reproductive morphology Fruits

Pod dehiscent, (8)10-23·6 x 2-3·4(4) cm., oblong, flat or slightly transversely plicate, glabrescent, glossy, eglandular, less prominently and closely venose than in A. adianthifolia, pale-brown to reddish-brown or purplish.

Morphology Reproductive morphology Seeds

Seeds 8-12 x 8-10 mm., flattened.
