Justification
A widespread (EOO 10 029 km²), but rarely recorded habitat specialist, known from only a few, widely scattered records. It is quite likely overlooked, and not suspected to be in danger of extinction.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape, KwaZulu-Natal
Range
Underberg to Bizana, and near Nkandla.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Forest
Description
Damp, shady slopes in forests or shaded streamsides in sheltered kloofs, as well as forest margins.
Threats
Although this species has been recorded from highly transformed areas such as Ngele (timber plantations), Underberg (timber plantations and crop cultivation) and Bizana (timber plantations, crop cultivation and human settlements), forests have been historically protected. In some areas, this species' habitat may be affected by alien invasive plants, but as it grows along pathways and forest margins it is quite likely somewhat resilient to disturbance. It is not suspected to be threatened.
Population

A widespread, but rarely recorded habitat specialist. An annual herb, and fairly common around Ngele Mountain (Hilliard and Burtt 1971), but elsewhere known from scattered records. It is possibly overlooked, as Senecio species are difficult to identify.
