Assessment Date

Assessor(s)
M.M.P. Mogale & L. von Staden
Justification
A relatively widespread (EOO 10 293 km²), but rarely recorded species known from fewer than 10 locations and declining due to ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
Port Elizabeth to Komga and Cathcart.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Amathole Montane Grassland, Bhisho Thornveld, Sundays Thicket, Groot Thicket
Description
Stony flats and slopes.
Threats
Threatened by ongoing habitat loss to urban expansion around Port Elizabeth, where it was last recorded in 1933, and is now possibly locally extinct. Recent field observations from the Stutterheim-Cathcart area indicate that the species is threatened by habitat degradation due to overgrazing.
Population

S. flanaganii is rarely collected and poorly known. It is difficult to distinguish from S. bicolor and S. longituba, and may be misidentified and overlooked. It is known from only a few, rather disjunct records scattered over a wide area, but it occurs in a botanically poorly explored area and field surveys may reveal it to be more common than records suggest.
