The bark on maturing, woody Searsia lucida stems may be longitudinally lined or faintly ridged and grey-brown to reddish brown in colour. Some parts in picture are blotchy, maybe caused by lichen, or the resin sometimes found upon stems. Young branches usually have raised lenticel dots for some time.
The wood of S. lucida is hard and dense, good for making fence posts. The bark, also from the roots, has been used in tanning (Coates Palgrave, 2002; Pooley, 1993; iNaturalist).
