The bark on major stems of Rhamnus prinoides is grey to brown, covered in conspicuous whitish lenticels. Lenticels are airy aggregations of cells within the bark of certain trees. On old trees the main stems become dark brown.

The wood is whitish, hard and heavy. Big pieces are not often found, as the tree seldom grows very big, reducing the uses of the wood to the manufacture of small household articles (Coates Palgrave, 2002).
