The fragrant, white flowers of Ozoroa engleri grow in stem-tip and upper leaf axil sprays. The small flowers are cream-coloured, about about 2,5 mm long. Ozoroa is a Greek word meaning odoriferous. Flowering happens from before midspring to summer. Bees are attracted to the flowers.

The kidney-shaped or bean-shaped to rounded fruit of O. engleri is a thinly fleshy drupe. The fruit grow in clusters on sometimes reddish stalks. Initially coloured pale green with a few red-brown spots, the fruit becomes black and wrinkled as it ripens. Fruit dimensions are about 10 mm long and 5 mm wide.

These resinous fruits are ground up by some traditional populations for use in dressing hair (Coates Palgrave, 2002; Schmidt, et al, 2002; Van Wyk and Van Wyk, 1997; Pooley, 1993; iNaturalist).
