Conservation status

Diselma archeri

Hooker f. 1857

Common names

Chestnut pine (Farjon 2005).

Taxonomic notes

The sole species in Diselma Hooker 1857. Syn: Fitzroya archeri Bentham et Hooker (Vidakovic 1991). Lectotype R.C. Gunn s.n., "summit of the western mountains and falls of Meander," 1849.03.09, K.


A dioecious shrub or small tree, 1-5-6 m tall, variously of compact or straggling habit, branchlets divided into fine sprays. Leaves scale-like, closely pressed and overlapping, alternately opposite or sometimes whorled, blunt at the apex. Male cones terminal, oblong, with the stamens in 3 or 4 pairs. Female cones terminal, solitary, small, globose, 5 mm across, composed of two pairs of scales, the upper pair fertile, with 2 seeds. Seeds small, with 2-3 wings. Chromosomes n = 11 (Dallimore et al. 1967, Vidakovic 1991).

This species can be confused with Microcachrys tetragona and Pherosphaera hookeriana, two Tasmanian podocarps that are also shrubs with very small scale-like leaves. However, the female cones, although small, are easily distinguished.

Distribution and Ecology

Tasmania: the western coast ranges and Lake St. Clair, at elevations of 910-1220 m (Dallimore et al. 1967). Hardy to Zone 8 (cold hardiness limit between -12.1°C and -6.7°C) (Bannister and Neuner 2001).

Big tree

It is reported to grow as a tree, at sizes up to over 10 m tall and 60 cm dbh, at Mount Read near Roseberry (Corbett [no date]).
