The scented, cream-coloured flowers of Senegalia senegal var. leiorhachis grow from the upper leaf axils, usually at the nodes before the leaves.
The flower spikes or catkins are often solitary, the rare cluster has as many as three. The inflorescence stalks are hairless, the rachises usually as well. The spikes are 5 cm to 8 cm long and 1,5 cm to 2,2 cm in diameter. Flowering occurs from late winter to early spring, often before the trees come into leaf.
The fruit is a straight, flat pod about 9 cm long and 2 cm wide, sometimes with minor undulations. Its base is tapered, the tip rounded or pointed, not beaked. The pod is khaki to pale brown, dehiscent when ripe, usually seen on the tree after midspring.
About six flattish, circular, i.e. disc-shaped seeds grow in one pod. They are yellow-green, becoming fawn or pale brown when ripe; a horse-shoe or U-shaped mark present on the sides (Carr, 1976; Coates Palgrave, 2002; Van Wyk and Van Wyk, 1997; Schmidt, et al, 2002; iNaturalist).
