Assessor(s)

Justification
A very poorly known taxon, known from a single collection more than 100 years old. It is possibly extinct, but further study may also indicate that it is not a valid taxon, as the genus Cotula is in need of revision.

South African endemic
Provincial distribution
Western Cape

Cape Flats.

Terrestrial
Major habitats
Fynbos
Description
Unknown, possibly sandy flats.
Threats
Habitat loss to urban expansion is likely to have caused the extinction of this species.
Population

There are no known collections of this species in South African herbaria. The type specimen was collected on the Cape Flats between Paarden Eiland, Bloubergstrand and Tygerberg (Harvey 1894), where it is now likely to be locally extinct due to habitat loss to urban expansion. It is possibly a doubtful species, as it is not included in recent treatments of the Cape Flora (Goldblatt and Manning 2000, Manning and Goldblatt 2012). The genus Cotula is in need of revision, and species are difficult to identify. Further research is needed.
