Conservation status

Callitris tuberculata

R. Br. ex R.T. Baker et H.G. Smith 1910

Common names

Mallee pine (Hill 1998).

Taxonomic notes

Some authors regard this species as synonymous with Callitris preissii or C. verrucosa, but Hill (1998) differentiates it on the basis of female cone characters and distribution. See further discussion in the "Taxonomic notes" for Callitris preissii.

Description

Shrubs or small trees to 8 m tall, single- or multi-stemmed. Leaves on ultimate branchlets 2-4 mm long, green-or gray green, with rounded upper surface. Pollen cones clustered, cylindrical, to 5 mm long. Seed cones solitary or clustered on stout, apically expanded branchlets; globular, 20-25 mm diameter, persistent holding seeds for several years after maturity; cones scales 6, thick, irregularly tuberculate with tubercles up to 3 mm across, united to form a thick cone base, not spreading widely after opening, alternate scales reduced, larger scales obtuse; columella thick, 2-4 mm long. Seeds numerous, dark brown, with 2-3 wings 4 mm wide (Hill 1998).

Distribution and Ecology

Australia: Western Australia, widespread on red desert sandhills, plains, coastal dunes and headlands (Hill 1998).

The IUCN does not recognize this taxon as distinct from C. preisii. Yet, it has a limited range and the area of occupancy seems not to have been assessed. Its conservation status is therefore "not evaluated" under IUCN criteria.

Remarkable Specimens

Observations

Remarks

Hybrids with C. preissii are found from the edges of the Great Victoria Desert west to the Murchison River estuary (Hill 1998).
