The fruit of Combretum mossambicense is the typical winged samara found on most Combretum species, more often five-winged than four-winged in this species.
The fruits are downy, sometimes densely woolly, the wings pale straw-coloured. Older fruit may turn browner. They become 3 cm long and 2,5 cm wide. Fruits are seen on the plant from mid-spring to midsummer.
Before the fruit and even before the new spring leaves, there has been a multitude of sweetly scented inflorescences grown from leaf axils. Each inflorescence comprises small white (or sometimes tinged pink) flowers in a globular spike, carried horizontally. The profuse flowering of these plants turns them into a spectacular sight in season, enhanced first by the absence of leaves, then by blanched leaves growing near the flowers.
The stamens comprising long white filaments and red-brown to reddish purple anthers protrude far beyond the five pointed petals that are spoon-shaped and slightly recurving.
Flowering commences late in winter continuing until mid-spring, before the leaves appear. The still closed buds are purple to black and hairy.
C. goetzei growing in the Tete province of Mozambique is very similar to this plant but lacks the hairiness on its fruits (Carr, 1988; Coates Palgrave, 2002; Schmidt, et al, 2002; Mannheimer and Curtis, (Eds.), 2009; iSpot; http://redlist.sanbi.org).
