Lagarostrobos franklinii is a species of conifer native to the wet southwestern corner of Tasmania, Australia. It is often known as the Huon pine or Macquarie pine, although it is actually a podocarp (Podocarpaceae), not a true pine (Pinaceae). It is the sole species in the genus Lagarostrobos; one other species L. colensoi (endemic to New Zealand) formerly included has been transferred to a new genus Manoao. The genus was also formerly included in a broader circumscription of the genus Dacrydium. In molecular phylogenetic analyses Lagorostrobos was found to be related to Parasitaxus (a parasitic and monotypic genus from New Caledonia) and Manoao, but their exact relationships are unresolved.
The wood is highly prized for its golden yellow colour, fine grain, and natural oils that resist rotting. The chemical giving the timber its unique smell and preservative qualities is methyl eugenol.
It has been planted in the grounds of Crathes Castle, Aberdeenshire, and has done well. Two healthy specimens can also be found at Torosay Castle, Isle of Mull.
It is a slow-growing, but long-lived tree; some living specimens of this tree are in excess of 2000 years old. It grows to 10 to 20 m tall, exceptionally reaching 30 m, with arching branches and pendulous branchlets. The leaves are spirally arranged, very small and scale-like, 1 to 3 mm long, covering the shoots completely. It is dioecious, with male (pollen) and female (seed) cones on separate plants. The male cones are yellow, 5 to 8 mm long and 1 to 2 mm broad. The mature seed cones are highly modified, berry-like, with 5 to 10 lax, open scales which mature in 6–8 months, with one seed 2 to 2.5 mm long on each scale. Unlike the closely related New Zealand genus Manoao, the scales do not become fleshy and are water-dispersed, not bird-dispersed.
