| Flower/Leaf Bud Description | The egg-shaped growth buds are reddish-brown and between 20 and 30 millimetres (0.79 and 1.2 in) long. They are short pointed, slightly rotated and very resinous. |
| Leaf Description | The dark and mostly shiny needles are pointed and 4-8 cm long and 1-2 mm wide. The needle edge is weak to clearly serrated. The needles are usually in pairs on short shoots and rotated. Needles are retained for an an average of four to six years. |
| Fruit Description | The 3-7 cm cones often need exposure to high temperatures (such as from forest fires) in order to open and release their seeds, though in subsp. murrayana they open as soon as they are mature. The cones have prickles on the scales. |
