Superb Groundsel is a glaucous, long-lived perennial shrub, growing to 1 m high (Jessop & Toelken 1986; Leigh & Briggs 1992), with bright yellow flower heads (Leigh & Briggs 1992).

This species is confined to the Northern Mt Lofty Ranges and Southern Flinders Ranges of SA (Davies 1986, 1992). In 1986, there was only one known population of 43 plants, but in the following nine years, a further 32 populations, containing more than 1900 plants, were discovered (Davies 1986, 1995b).

In the Northern Lofty Ranges there are three known populations, at Orroroo, Black Rock and Newikie Creek (Davies 1992, 1995b). In the past, specimens have also been collected from Marne R. Gorge and from an area bounded by White-Yarcowie in the N, Spalding in the W and Robertstown in the S and E (Davies 1986).

Both the Orroroo and Black Rock populations were discovered between 1986 and 1992. They both occur on private land (Davies 1992). The Black Rock population contained two plants at the time (R. Bates, 1987 pers. comm. in Davies 1992). The size and condition of the other population was not known (Davies 1992).

A third population of 1000 plants was found along Newikie Ck on private land in the Hundred of Mongolata, in the Mid North (Lofty Ranges) (R. Bates, pers. comm. 1994 in Davies 1995b).

In the Southern Flinders Ranges Populations there are 28 known populations. 25 of the 28 populations are conserved in Dutchman's Stern Conservation Park, two populations are just outside the park and one is at Horrock's Creek to the S (Davies 1992, 1995b). In the past, specimens have also been collected from scattered localities between Buckaringa Gorge in the N and Spear Ck in the S (Davies 1986).

Thirteen populations were discovered between 1986 and 1992 (Davies 1986, 1992). Five of these occurred within Dutchman's Stern CP, consisting of 100, 30, 2, 2 and 1 individual(s). Only one of these five populations contained juveniles (Davies 1992).

The remaining eight populations were adjacent to the park but seven have since been incorporated into it due to an extension in 1993 (Davies 1995b). The largest, containing 465 individuals, was adjacent to the northern boundary. This population contained very few seedlings. Six of the other seven unconserved populations occurred on the crest, slopes and gullies of the ridge N of the park, with a total of 147 individuals. The eighth population, consisting of six individuals, occurs W of the Park (Davies 1992).

Between 1992 and 1995 three populations containing 100+, 50+ and four individuals were found in the newly acquired area of the park. The largest of the three consisted mostly of seedlings, in an area burnt in the preceding year. Ten more populations were also found in the park, totalling in excess of 40 individuals. A further population of an estimated several thousand plants was located in privately owned land to the N of the new park area (Davies 1995b).

In 1994 a population of one adult and a large number of seedlings was discovered, in the central tributary of Horrock's Ck (south of Spear's Creek) (A. Stefanovic, pers. comm. 1994; H. Vonow 1994 in Davies 1995b).

The species is mostly confined to rocky creek banks and rocky gorge/valley slopes (Jessop & Toelken 1986; Leigh & Briggs 1992), though it has been recorded in the past in a creek bed, in drainage lines, on the edge of an erosion gully, in "sandhills" and in "arid hills" (Davies 1986, 1992) One herbarium record mentions an arid sand hill habitat (Davies 1986).

It has been found over the years on slopes facing almost every direction (W, SW, S, SE, E, NE and NNE) (Davies 1986, 1992). It grows in variable soils of yellow-red-grey-brown coloured loams (sometimes with layers of pebbles) and clay loams of pH 6.5 -9. Scattered rocks and outcrops of metasiltstone occur at several sites (Davies 1992; Leigh & Briggs 1992).

Associated vegetation communities according to Davies (1986, 1992) and Leigh & Briggs (1992) are:
- herbland or grassland, often with Lomandra effusa, Triodia irritans or Stipa sp;
- tall open-shrubland dominated by Pittosporum phylliraeoides, Heterodendrum oleaefolium, Cassinia laevis, Eremophila longifolia, Acacia calamifolia and Bursaria spinosa;
- Acacia calamifolia sparse heathland with a mid-dense understorey of T. irritans;
- Cassinia laevis, Sida calyxhymenia low sparse-shrubland (with and without A. calamifolia), with a sparse ground stratum;
- C. laevis and T. irritans associations;
- Callitris columellaris and Eucalyptus camaldulensis woodland and open-woodland with a very sparse shrub strata.

Flowers are borne from late July to Nov. (Davies 1986; Jessop & Toelken 1986; Leigh & Briggs 1992).

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.
