Hartweg's pine
A tall growing evergreen pine growing up to 31m (103ft) in height on a long clear straight trunk, capable of reaching 1.2m (4ft) in diameter when mature. Its bark is deeply furrowed and divided into plates and brown to grey in colour. The flattened oval shaped canopy is restricted to the upper parts of the trunk on mature specimens and composed of stiff dark green needles to 20cm (8in) long, usually appearing in groups of five. The cones around 8 cm (3in) long are oval with a tapering tip and appear in whirls of five or six. They are purplish brown when young becoming brown with age and with a black tip to each of the scales.
