Scientific name: Senecio georgianus

Common name: Grey Groundsel

Grey Groundsel was an erect, perennial shrub which grew 30–60 cm high. When young, the species was covered with white cottony wool which usually persisted on the underside of the leaves. The leaves were linear or lance-shaped, 2–8 cm long, with smooth or slightly toothed margins. The tiny yellow flowers were densely clustered into small branched flower heads which were arranged at the ends of the stems. Each flower head was surrounded at the base by a cylindrical covering of about 12 bracts (modified leaves), 5–7 mm long. The individual flowers were minute and bisexual. Fruit were small, dry and hairy with the seed distinct from the fruit wall. The species flowered from August to September (Leigh et al. 1984).

Grey Groundsel has been collected in NSW, South Australia, Victoria, Western Australia and Tasmania, but is now considered extinct (Davies 1992). This species was never considered common despite being collected from such a large area (Leigh et al. 1994)..

Collection locations included Clarence River, Macquarie River and Lake George, NSW; 'Salt Gully' north of Port Augusta, South Australia; Macalister River, Mitta-Mitta Range and Lake Omeo, Victoria; Darling Range, near Perth, Western Australia; and Derwent River near Risdon Cove, and once at the 'Agricultural Settlement, Hobart', Tasmania (Leigh et al. 1984)

All collections are old (prior to 1900) except for Victorian collections which were made in 1972. Victorian populations, at the time, were described as rare and localised. Grey Groundsel specimens from Tasmania and NSW are held by the British Museum (Leigh et al. 1984).

This species is presumed extinct and no extant populations are known.

Grey Groundsel is recorded as occurring in savannah grassland, undulating grassy eucalypt woodland, grassy sub-alpine ridges and collections frequently occurred in association with major rivers and lakes (Davies 1992; Leigh et al. 1984).

Grey Groundsel was distinguished from closely related taxa by the narrow-lanceolate leaves, numerous florets (up to 40) and the usually tomentose indumentum (Harden 1992).

Clearing and domestic stock grazing appear to have caused the extinction of Grey Groundsel. Collection locations in south-east Australia have been resurveyed and it was observed that each site has been converted to pasture (Leigh et al. 1984).

Although this species is presumed extinct, further field searches could be worthwhile (Leigh et al. 1984).

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.
