Characteristics

Tree up to 15 m high, with rough dark brown to grey bark; branchlets, petioles, leaf-rhachillae and peduncles sparingly to densely brown-pubescent or tomentellous. Leaves: petiole 2-7 cm long, with a gland just below the junction of the solitary pair of pinnae; rhachillae 5-16 cm long, often with a gland just below the appressed-pubescent with the hairs longer and denser than on the calyx; interfloral bracts spathulate, 2-3 mm long. Calyx tubular-campanulate, up to 4.5 mm long, lobes up to 1.5 mm long, appressed-pubescent. Corolla up to 6 mm long, lobes up to 2.25 x 0.75 mm, appressed-pubescent. Stamens 10, filaments free, up to 1 cm long; anthers up to 0.6 mm long, each with a caducous apical gland. Ovary up to 3 mm long, 1.5 mm wide, pubescent; style glabrous, up to 8 mm long; stigma terminal. Pods obliquely obovate to oblanceolate, 9-12 x 3.2-5 cm, woody, compressed, brown-tomentellous at least in part, dehiscing from the apex downwards, the 2 valves recurving. Seeds lying transversely or obliquely in the pod, each sunk in a depression in the valve, compressed, brown, ±1.2 x 0.9 cm, smooth; areole ±6 x 4 mm.
More
A small to medium-sized tree 6-15 m in height; occurring at low altitudes often on deep sand in hot, dry types of woodland and sandforest. Bark: brown to grey, rough and flaking, branches with lenticels. Leaves: with 1 pair of pinnae, each pinna bearing 3-6 pairs of leaflets; leaflets large, narrowly elliptic to almost rounded, 2.5-10 x 1.3-5 cm, hairy at first becoming almost hairless above, apex shortly attenuate, base square to shallowly lobed; petiole 2-7 cm long with a gland at the top between the pair of pinnae. Flowers: yellow, in spherical heads, up to 1.5-2 cm in diameter; stamens conspicuous, long, fragrant (Sept.-Nov.). Fruit: a thickly woody pod, obliquely obovate to oblanceolate (similar in shape to that of Baikiaea plurijuga), 9-12 x 3-5 cm, covered with brownish velvety hairs; dehiscing from the apex downwards, the 2 halves curving backwards throwing out the seeds which have been recorded up to 25 m away from the tree (Sept.-Jun.).
Leaves with petioles 2-7 cm. long; pinna-rhachides 5-16 cm. long; leaflets in 4-6 pairs, (3·5)4-7·5 x 2-4·2 cm., narrowly ovate or rarely narrowly elliptic, rounded or often slightly cordate at the base, tomentose on both surfaces when young, the upper becoming glabrous, the lower ± densely pubescent at maturity.
Flowers in heads c. 1·5 cm. in diam., on axillary peduncles 2-3·5 cm. long; pedicels c. 1·5 mm. long, appressed-pubescent with hairs longer and denser than on the calyx; interfloral bracts 2-3 mm. long, spathulate.
Tree, up to 15 m high. Leaves 2-pinnate. Flowers in heads up to 18 mm in diameter on axillary peduncles. Pods obliquely obovate, 90-120 x 30-50 mm, woody. Flowers yellow.
Tree up to 15 m. high, with rough brown to grey bark; branchlets, petioles, leaf-rhachides and peduncles densely brown-pubescent or tomentellous.
Pod 9-14 x 3·2-8 cm., brown-tomentellous at least in part.
Flowers 4·5 (male)-6 (hermaphrodite) mm. long, yellow.
