Halocarpus bidwillii, commonly known as the mountain pine or bog pine, is a species of conifer in the family Podocarpaceae. It is endemic to New Zealand. It is an evergreen shrub favouring both bogs and dry stony ground, seldom growing to more than 3.5 m (11 ft) high. The leaves are scale-like on adult plants, 1–2 mm (0.039–0.079 in) long, arranged spirally on the shoots; young seedlings and occasional shoots on older plants have soft strap-like leaves 5–10 mm (0.20–0.39 in) and 1–1.5 mm (0.039–0.059 in) broad. The seed cones are highly modified, berry-like, with a white aril surrounding the single 2–3 mm (0.079–0.118 in) long seed.
