Tree on Mt. Read, where the oldest known huon pine was found. [Chris Bell, APSTAS].


Tree in habitat (ANBG [no date]).


Huon pine (Tasmania Parks and Wildlife Service 1999).


Distinguishing characteristics include: "cone pendulous on decurved cone axis, pale green to white; fertile bracts spreading spoon-shaped, separated by distinct internodes; ovules obliquely inclined towards cone axis, partially inverted, one with pollination drop in early stage of resorption; cone 6 mm x 2 mm." [R. Lamberts] (Molloy 1995).

Lagarostrobos franklinii

(Hook f.) Quinn 1982

Common names

Huon pine (Silba 1986), Macquarie pine.

Taxonomic notes

Syn: Dacrydium franklinii Hooker (Quinn 1982). The sole species in Lagarostrobos C.J. Quinn 1982. A former second species, L. colensoi, has lately (Molloy 1995) been segregated to the monotypic genus Manoao.

Lagarostrobos was formerly included in Dacrydium, but de Laubenfels (1969) segregated the genus Falcatifolium and Quinn (1982) further segregated the genera Halocarpus, Lagarostrobos, and Lepidothamnus, leaving Dacrydium sensu strictu. These segregations were made on the basis of differences in female cone morphology, a criterion that has been used as the taxonomic basis for differentiating all genera in the Podocarpaceae. "The name Lagarostrobos refers to the lax open nature of the female cone" (Quinn 1982).


For the genus: "Trees with narrow, linear, subulate decurrent juvenile leaves arranged distichously; adult leaves broad appressed imbricate scales. Male cones solitary, terminal, sessile. Female cones terminal on branchlets that are generally markedly decurved, very distinctive in the lax nature of the young cone. Ovules borne in a median position on the adaxial surface of the fertile bract, initially obliquely inclined toward the cone axis but becoming virtually erect at maturity. The epimatium forming a fleshy asymmetrical sheath around the base of the seed and up to half its height at maturity; seeds not compressed, maturing in 1 year" (Quinn 1982).

For the species: A straight-trunked, pyramidal tree 21-30 m tall, 70-100 cm dbh, bark gray (2, 9). "Branchlets slender. Leaves small, scale-like, about [1 mm] long, closely pressed, strongly keeled, blunt and concave in mature plants, resembling those of a cypress but differing markedly in the presence of scattered white stomata on the back. Cones very small, terminating the branchlets, each with 4-8 scales. Seeds globose, about [2 mm] in diameter" (Dallimore et al. 1967).

Distribution and Ecology

Australia: Tasmania, along river systems and in wet mountains (e.g. Mt. Read) near the southern and western coasts at altitudes of 150 to 600 m (Dallimore et al. 1967, Allen 1998). Within its range, mean annual temperature is 9.6°C, with an average minimum in the coldest month of 2.5°C, and a mean annual precipitation of 2106 mm (Biffin et al. 2011, Table S5). See also publications by Shapcott and Read, listed below. You can also create a highly detailed map, and access specimen data, using the "search" function at the Australia Virtual Herbarium.

"These trees reproduce vegetatively (by layering and root suckering) as well as by seed. The male and female cones are usually found on separate trees and the seeds are spread by water or by birds" (ANBG [no date]).

Hardy to Zone 8 (cold hardiness limit between -12.1°C and -6.7°C) (Bannister and Neuner 2001).

Big tree

[There are] "individuals that would take the arm spans of at least 3 people, possibly 4, to encircle" (Allen 1998).


A specimen collected by Cook et al. in 1991 (Brown 1996) had a crossdated age of 1089 years. Living trees sampled by increment borer have yielded ring counted ages of up to 2500 years, and since these were not pith dates, it seems likely that there are living trees with ages in excess of 3000 years (Balmer 1999). The trees in the oldest stand, on Mt. Read near Roseberry, comprise a single male clone. Sediments from Lake Johnston on Mt. Read contain Huon pine pollen 10,500 years old, so it is plausible that this clone is more than 10,000 years old (Corbett [no date]). Among conifers, this is the longest period of time for which we have any indication of the continued persistence of a unique genetic individual, although it is possible that comparable ages could be matched by Sequoia sempervirens and Taxus baccata. Much older clone ages have been demonstrated in non-conifers; currently the record seems to be an age of 43,600 years attributed to a Lomatia tasmanica clone that, somewhat ironically, grows in the range of Huon pine (DEWHA 2010).


Has been used in radiocarbon time scale calibration (Barbetti et al. 1995) and studies of long term temperature variation (Cook et al. 1991, 1992, 1996). Because the wood is extremely rot resistant, subfossil specimens have enabled the construction of a continuous tree ring record covering over 12,000 years at the Stanley River site (Pepper 1999). This is one of the world's longest continuous tree-ring records.


The fragrant, soft wood is used for boatbuilding, furniture, cabinetry, turning and carving. It is a highly regarded specialty wood due to its aesthetic qualities and the appeal of owning something made from what is now thought to be the longest-lived tree in Australasia. The wood supply is restricted, natural stands having been largely logged or protected, but much of the logging was in areas slated for inundation due to hydroelectric development and the wood was stockpiled. At the current usage rate of about 500 m3/yr, the supply of sawlogs is expected to last 50 years (Timber Research Unit 2007). An oil obtained from the wood is used as a paint preservative. "The oil has been used for dressing wounds, treating toothache and as an insecticide. The timber is resistant to attack by rot and marine organisms" (ANBG [no date]). The rot resistance and sweetish odor of the wood is due to the presence of the essential oil methyl euganol (Corbett [no date]), which has been synthesized and is approved for us as a pesticide in the USA.


The Mt. Read forest discussed above, in the Lake Johnston Nature Reserve, sounds to be worth a visit. Besides huon pine, the area also hosts most of Tasmania's other endemic conifers, including Athrotaxis selaginoides, A. cupressoides, A. laxifolia, Diselma archeri, Microcachrys tetragona, and Phyllocladus asplenifolius. Diselma, normally a shrub, grows as a tree at sizes up to 10 m tall and 60 cm dbh (Corbett [no date]).


Huon pine was named for the river in D'Entrecasteaux Channel, in the bed of which logs of the timber were found (thus Huon is a proper noun). It was first recorded by Alan Cunningham in 1818 (Dallimore et al. 1967).

"Lagarostrobos comes from two Greek words lagaros= thin, and strobos= cone. The species name franklinii honours Sir John Franklin, 1786-1847, naval captain, arctic explorer and governor of Tasmania from 1836 to 1843" (ANBG [no date]).
