Portulaca filsonii
Portulaca filsonii is a plant in the Portulacaceae family, endemic to central Australia in the Northern Territory.
It was first described by James Hamlyn Willis in 1975 from a specimen collected in Kings Canyon. The holotype, and isotype,, were both collected by Willis in 1966. The name accepted by the Council of Heads of Australasian Herbaria is the later name of Sedopsis filsonii, created as a new combination by Willis in 1977.
The species epithet, filsonii, honours Rex Bertram Filson.
Portulaca filsonii is listed as "Near Threatened" under the TPWCA Act.
