Threats
The threats to this taxon are not known. One subpopulation was recorded in a protected area, but it was last seen in 1959. The second subpopulation occurs in an area where there is little human impact, except for livestock grazing. The impact of grazing on this taxon is not known.
Population

This taxon is known from only two collections, and was last recorded in 1968. Recent field surveys around Garies failed to relocate it at a locality known through historical records (Klak et al. 2015). It is apparently rare, but may also be overlooked. The population trend is not known, but there are no known severe threats and as an annual species it is possibly resilient disturbance.
