[4][5] Fresh, fixed and dried flowers tested have been found to be sterile, with no evidence of viable pollen, suggesting that the species cannot reproduce from seed.

[2][6] This species was first formally described by Australian taxonomic botanist Lawrence Alexander Sidney Johnson in 1962 and the description was published in Contributions from the New South Wales National Herbarium.

Morrison, "discovered" the species in a localised population on a steep hillside similar in features and aspect to the type locality, using information from Lawrence Johnson's original 1962 notes.

[6] This species is only known from a single population, occurring on a steep slope located within the Lake Keepit Recreation Area, north-east of Gunnedah in New South Wales.

[5][1] [2] The vegetation of the population's site is open woodland with tall shrubs and sparse groundcover, dominated by the conifer Callitris glaucophylla in the highest stratum.

Other common ground-cover plants include Verbascum virgatum, which is also an introduced species, and the native grasses Themeda australis, Cymbopogon obtectus, Heteropogon contorta and Aristida sp.

Threats to the species include disturbance and soil erosion from recreational activities, browsing from livestock and feral rabbits, damage and landslips from potential floods, fire suppression and possible introduction of diseases.
