The pistol bush or Duvernoia adhatodoides grows to a height of 6 m in its long and narrow distribution area along the east coast of South Africa from the Eastern Province and inland to the Lowveld in Limpopo; some specimens also occur in Gauteng.
The leaves are shiny, dark green, opposite, elliptic and broadly tapering towards the tips, with wavy margins. The bark is rough and brown, fissured on mature specimens. The young branches are four-angled and velvety.
The tree is grown from cuttings in frost free environments (Coates Palgrave, 2002; www.plantzafrica.com).
