The Tuggeranong Lignum is a sprawling, scarcely woody shrub with branches growing to approximately 80 cm long. It eventually becomes a loose tangled mound of wiry stems, growing to 1 m high and 1-2 m across (Makinson & Mallinson 1997; Mallinson et al 1998).

This species is known only from flood terraces on the eastern bank of the Murrumbidgee River near Tuggeranong on the southern outskirts of Canberra (NSW Southern Tablelands botanical district) (Makinson & Mallinson 1997). It is as yet only known from the Pine Island area in the Murrumbidgee Corridor Nature Reserve (Mallinson et al. 1998).

The Tuggeranong Lignum was described from a single female plant and six male plants discovered in 1997. In May 1999, an additional male plant was discovered a short distance from the other seven plants. Although extensive searches for other specimens have taken place, this population appears to be the only one in existence (ACT Government 1999).

This species is known only from flood terraces on the eastern bank of the Murrumbidgee River at an altitude of about 550 m, in areas of rocky outcrop with pockets of silty sand soil (Makinson & Mallinson 1998).

The plants occur on river bank terraces prone to occasional flooding, and on an adjacent gentle slope. This section of the river is typified by rapids, sand reaches and boulders, with uneven rocky flood terraces, some up to about 100 m wide, at 2-8 m above normal river level. Down stream of Pine Island the river forms rugged gorges. The higher surrounding terrain is gently sloping, open and undulating (Mallinson et al. 1998).

The last flood to have inundated levels on which at least three of the known plants occur was in 1991. The sole female plant was probably inundated by a smaller flood in 1994. The plants are situated 1.5 m above normal summer river levels (Mallinson et al. 1998).

It grows in medium to course-textured alluvium, mainly quartzitic sand and gravel, with local richer pockets of silty sand soil. Soil around all plants have a low organic content. The species also grows in crevices amongst larger rock outcrops (Mallinson et al. 1998).

This species is found in a disturbed riparian shrub and woodland association, heavily invaded by exotic weeds. The patchy, open tree layer comprises remnant native species and introduced willows. The understory varies from densely vegetated to open with scattered grasses and shrubs, with areas of bare rock and sand. This species is found in both exposed situations in crevices on nearby bare rock, or tangled among other vegetation (Mallinson et al. 1998).

Flowering has been observed in this species from Dec. to late Feb. (Mallinson et al. 1998).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
